Processing Materials: pebble, calcite, granite, quartz, concrete, dolomite, bluestone, limestone, iron ore, coal gangue, construction waste, ferrosilicon, basalt, sandstone, rocks, ore, glass, cement clinker and some metals.

While the working principle of cone crusher is laminated crushing. The rolling wall continuously moves toward the broken wall, and the material between the two is squeezed to be pulverized.

Here is the working principle of impact crusher. The toothed counter-back plate rebounds and falls freely after the material reaches the top of the vortex breaking chamber and then hits and crushes constantly with subsequently upward impacting materials.

Jaw crusher processes the hardest and medium-hard stones as the first crusher, and impact crusher and cone crusher can both act as secondary crushing devices, but the hardness of the two broken materials is not the same.

Cone crusher mainly crushes some harder materials, such as granite, basalt, river pebbles and so on, while impact crusher is used to crush the materials that are not so hard, such as limestone, limerock, etc. These materials above can be crushed firstly by jaw crusher.

The discharge size of jaw crusher is widely adjusted from 10-400mm, which is coarser than that of the second-stage crusher. But the discharge sizes of the secondary crushers are not the same. Generally, the discharge granularity of cone crusher is finer than that of impact crusher.

In the actual production, jaw crusher can be used wisely in mining, construction, building materials, etc. But cone crusher is more often used in ore processing and impact crusher in construction and building material processing.

The jaw crusher is a kind of early crushing device. With simple and firm structure, reliable operation, easy maintenance and service and relatively low costs in production and construction, jaw crusher is still widely used in coarse, medium and fine crushing for various ores and rocks with compressive strengths ranging from 147 to 245 MPa in metallurgy, chemistry, building materials, electricity, transportation and other industries.

The working principle is: the motor drives the belt and the pulley, and the mobile jaw is moved up and down through the eccentric shaft. The angle between toggle plate and mobile jaw increases when mobile jaw moves up, thereby the mobile jaw is closer to the fixed jaw, at the same time the materials are crushed or chopped to achieve the purpose of crushing;

the angle between toggle plate and mobile jaw decreases when mobile jaw moves down, the mobile jaw is separated from the fixed jaw under the action of the pull rod and the spring, meanwhile the crushed materials are discharged from the lower mouth of the crushing chamber.

The inertia required to crush the materials is provided by the flywheel, and the eccentric shaft generates eccentric motion which results in the gap getting closed. With the continuous rotation of motor, the mobile jaw works periodically to crush and discharge materials and finally achieve mass production.

Jaw crusher is a kind of heavy-duty machine and therefore require the solid construction. The external frame is usually made of cast iron or steel. The jaws are usually made of cast steel fitted with replaceable gaskets which are made of manganese steel or Ni-hard (Ni-Cr alloy cast iron). Jaw crushers are usually constructed in sections so that they can be transported easily when they are brought underground for operation.

In the mining and construction crushing industries, the jaw crusher at the front end of the production line, and its performance directly affects the quality and operation of the whole production line.

HXJQ Corporation has brought new breakthroughs in the production and upgrading of mines and gravel production lines and produced a series of jaw crushers in high quality and high standards with its over 40 years experiences and cases in crushing industry according to the market demand.

jaw crusher working principle

A sectional view of the single-toggle type of jaw crusher is shown below.In one respect, the working principle and application of this machine are similar to all types of rock crushers, the movable jaw has its maximum movement at the top of the crushing chamber, and minimum movement at the discharge point. The motion is, however, a more complex one than the Dodge motion, being the resultant of the circular motion of the eccentric shaft at the top of the swing jaw. combined with the rocking action of the inclined toggle plate at the bottom of this jaw. The motion at the receiving opening is elliptical; at the discharge opening, it is a thin crescent, whose chord is inclined upwardly toward the stationary jaw. Thus, at all points in the crushing chamber, the motion has both, vertical and horizontal, components.

It will be noted that the motion is a rocking one. When the swing jaw is rising, it is opening, at the top, during the first half of the stroke, and closing during the second half, whereas the bottom of the jaw is closing during the entire up-stroke. A reversal of this motion occurs during the downstroke of the eccentric.

The horizontal component of motion (throw) at the discharge point of the single-toggle jaw crusher is greater than the throw of the Dodge crusher at that point; in fact, it is about three-fourths that of Blake machines of similar short-side receiving-opening dimensions. The combination of favorable crushing angle, and nonchoking jaw plates, used in this machine, promotes a much freer action through the choke zone than that in the Dodge crusher. Capacities compare very favorably with comparable sizes of the Blake machine with non-choking plates, and permissible discharge settings are finer. A table of ratings is given.

The single-toggle type jaw crusher has been developed extensively. Because of its simplicity, lightweight, moderate cost, and good capacity, it has found quite a wide field of application in portable crushing rigs. It also fits into the small, single-stage mining operation much better than the slower Dodge type. Some years since this type was developed with very wide openings for reduction crushing applications, but it was not able to seriously challenge the gyratory in this field, especially when the high-speed modern versions of the latter type were introduced.

Due to the pronounced vertical components of motion in the single-toggle machine, it is obvious that a wiping action takes place during the closing strokes; either, the swing jaw must slip on the material, or the material must slip along the stationary jaw. It is inevitable that such action should result in accelerated wear of the jaw plates; consequently, the single-toggle crusher is not an economical machine for reducing highly abrasive, or very hard, tough rock. Moreover, the large motion at the receiving opening greatly accentuates shocks incidental to handling the latter class of material, and the full impact of these shocks must be absorbed by the bearings in the top of the swing jaw.

The single-toggle machine, like the Dodge type, is capable of making a high ratio-of-reduction, a faculty which enables it to perform a single-stage reduction of hand-loaded, mine run ore to a suitable ball mill, or rod mill, feed.

Within the limits of its capacity, and size of receiving openings, it is admirably suited for such operations. Small gravel plant operations are also suited to this type of crusher, although it should not be used where the gravel deposit contains extremely hard boulders. The crusher is easy to adjust, and, in common with most machines of the jaw type, is a simple crusher to maintain.

As rock particles are compressed between the inclined faces of the mantle and concaves there is a tendency for them to slip upward. Slippage occurs in all crushers, even in ideal conditions. Only the particles weight and the friction between it and the crusher surfaces counteract this tendency. In particular, very hard rock tends to slip upward rather than break. Choke feeding this kind of material can overload the motor, leaving no option but to regulate the feed. Smaller particles, which weigh less, and harder particles, which are more resistant to breakage, will tend to slip more. Anything that reduces friction, such as spray water or feed moisture, will promote slippage.

Leading is a technique for measuring the gap between fixed and moveable jaws. The procedure is performed while the crusher is running empty. A lead plug is lowered on a lanyard to the choke point, then removed and measured to find out how much thickness remains after the crusher has compressed it. This measures the closed side setting. The open side setting is equal to this measurement plus the throw of the mantle. The minimum safe closed side setting depends on:

Blake (Double Toggle) Originally the standard jaw crusher used for primary and secondary crushing of hard, tough abrasive rocks. Also for sticky feeds. Relatively coarse slabby product, with minimum fines.

Overhead Pivot (Double Toggle) Similar applications to Blake. Overhead pivot; reduces rubbing on crusher faces, reduces choking, allows higher speeds and therefore higher capacities. Energy efficiency higher because jaw and charge not lifted during cycle.

Overhead Eccentric (Single Toggle) Originally restricted to sampler sizes by structural limitations. Now in the same size of Blake which it has tended to supersede, because overhead eccentric encourages feed and discharge, allowing higher speeds and capacity, but with higher wear and more attrition breakage and slightly lower energy efficiency. In addition as compared to an equivalent double toggle, they are cheaper and take up less floor space.

Since the jaw crusher was pioneered by Eli Whitney Blake in the 2nd quarter of the 1800s, many have twisted the Patent and come up with other types of jaw crushers in hopes of crushing rocks and stones more effectively. Those other types of jaw crusher inventors having given birth to 3 groups:

Heavy-duty crushing applications of hard-to-break, high Work Index rocks do prefer double-toggle jaw crushers as they are heavier in fabrication. A double-toggle jaw crusher outweighs the single-toggle by a factor of 2X and well as costs more in capital for the same duty. To perform its trade-off evaluation, the engineering and design firm will analyze technical factors such as:

1. Proper selection of the jaws. 2. Proper feed gradation. 3. Controlled feed rate. 4. Sufficient feeder capacity and width. 5. Adequate crusher discharge area. 6. Discharge conveyor sized to convey maximum crusher capacity.

Although the image below is of a single-toggle, it illustrates the shims used to make minor setting changes are made to the crusher by adding or removing them in the small space between the crushers mainframe and the rea toggle block.

The jaw crusher discharge opening is the distance from the valley between corrugations on one jaw to the top of the mating corrugation on the other jaw. The crusher discharge opening governs the size of finished material produced by the crusher.

Crusher must be adjusted when empty and stopped. Never close crusher discharge opening to less than minimum opening. Closing crusher opening to less than recommended will reduce the capacity of crusher and cause premature failure of shaft and bearing assembly.

To compensate for wear on toggle plate, toggle seat, pitman toggle seat, and jaws additional shims must be inserted to maintain the same crusher opening. The setting adjustment system is designed to compensate for jaw plate wear and to change the CSS (closed side setting) of the jaw crusher. The setting adjustment system is built into the back frame end.

Here also the toggle is kept in place by a compression spring. Large CSS adjustments are made to the jaw crusher by modifying the length of the toggle. Again, shims allow for minor gap adjustments as they are inserted between the mainframe and the toggle block.

is done considering the maximum rock-lump or large stone expected to be crushed and also includes the TPH tonnage rate needing to be crushed. In sizing, we not that jaw crushers will only have around 75% availability and extra sizing should permit this downtime.

As a rule, the maximum stone-lump dimension need not exceed 80% of the jaw crushers gape. For intense, a 59 x 79 machine should not see rocks larger than 80 x 59/100 = 47 or 1.2 meters across. Miners being miners, it is a certainty during day-to-day operation, the crusher will see oversized ore but is should be fine and pass-thru if no bridging takes place.

It will be seen that the pitman (226) is suspended from an eccentric on the flywheel shaft and consequently moves up and down as the latter revolves, forcing the toggle plates outwards at each revolution. The seating (234) of the rear toggle plate (239) is fixed to the crusher frame; the bottom of the swing jaw (214) is therefore pushed forward each time the pitman rises, a tension rod (245) fitted with a spring (247) being used to bring it back as the pitman falls. Thus at each revolution of the flywheel the movable jaw crushes any lump of ore once against the stationary jaw (212) allowing it to fall as it swings back on the return half-stroke until eventually the pieces have been broken small enough to drop out. It follows that the size to which the ore is crushed.

The jaw crusher is not so efficient a machine as the gyratory crusher described in the next paragraph, the chief reason for this being that its crushing action is confined to the forward stroke of the jaw only, whereas the gyratory crusher does useful work during the whole of its revolution. In addition, the jaw crusher cannot be choke-fed, as can the other machine, with the result that it is difficult to keep it working at its full capacity that is, at maximum efficiency.

Tables 5 and 6 give particulars of different sizes of jaw crushers. The capacity figures are based on ore weighing 100 lb. per cubic foot; for a heavier ore, the figures should be increased in direct proportion to its weight in pounds per cubic foot.

The JAW crusher and the GYRATORY crusher have similarities that put them into the same class of crusher. They both have the same crushing speed, 100 to 200 R.P.M. They both break the ore by compression force. And lastly, they both are able to crush the same size of ore.

In spite of their similarities, each crusher design has its own limitations and advantages that differ from the other one. A Gyratory crusher can be fed from two sides and is able to handle ore that tends to slab. Its design allows a higher-speed motor with a higher reduction ratio between the motor and the crushing surface. This means a dollar saving in energy costs.

A Jaw crusher on the other hand requires an Ely wheel to store energy. The box frame construction of this type of crusher also allows it to handle tougher ore. This design restricts the feeding of the crusher to one side only.

The ore enters from the top and the swing jaw squeezes it against the stationary jaw until it breaks. The broken ore then falls through the crusher to be taken away by a conveyor that is under the crusher.Although the jaws do the work, the real heart of this crusher is the TOGGLE PLATES, the PITMAN, and the PLY WHEEL.

These jaw crushers are ideal forsmall properties and they are of the high capacity forced feed design.On this first Forced Feed Jaw Crusher, the mainframe and bumper are cast of special alloy iron and the initial cost is low. The frame is ribbed both vertically and horizontally to give maximum strength with minimum weight. The bumper is ruggedly constructed to withstand tremendous shock loads. Steel bumper can be furnished if desired. The side bearings are bronze; the bumper bearings are of the antifriction type.

This bearing arrangement adds both strength and ease of movement. The jaw plates and cheek plates are reversible and are of the best-grade manganese steel. The jaw opening is controlled by the position of an adjustable wedge block. The crusher is usually driven by a V-to-V belt drive, but it can be arranged for either V-to-flat or fiat belt drive. The 8x10 size utilizes a split frame and maybe packed for muleback transportation. Cast steel frames can be furnished to obtain maximum durability.

This second type of forced feed rock crusher is similar in design to the Type H listed above except for having a frame and bumper made of cast steel. This steel construction makes the unit lighter per unit of size and adds considerable strength. The bearings are all of the special design; they are bronze and will stand continuous service without any danger of failure. The jaw and cheek plates are manganese steel; and are completely reversible, thus adding to their wearing life. The jaw opening is controlled by the position of an adjustable wedge block. The crushers are usually driven by V-to-V but can be arranged for V-to-flat and belt drive. The 5x6 size and the 8x10 size can be made with sectionalized frame for muleback transportation. This crusher is ideal for strenuous conditions. Consider a multi jaw crusher.

jaw crusher | primary crusher in mining & aggregate - jxsc mine

Product Introduction JXSC jaw type rock crusher is usually used as a primary crusher and secondary crusher to reduce the size of medium-hard materials to smaller physical size. Jaw rock crushers are capable of working with the mobile crushing station, underground crushing because of its related small volume. Capacity: 1-1120TPH Max Feeding Size: 120-1200mm Application Mining, metallurgy, building materials, quarrying, gravel & sand making, aggregate processing, recycling, road and railway construction and chemical industry, etc. Suitable Material Granite, marble,basalt, limestone, coal, quartz, pebble, iron ore, copper ore, etc.

40 years of manufacturing and engineering experience keep us innovative and knowledge in the rock break machines and its applications, which thus provide reliable industry rocks crushers and solutions for every customer using jaw crusher manufacturers JXSC machines to meet their production goals. The jaw crusher machine family consists of different sized models that are designed to bring maximum output with minimum cost. Some workplaces have limited conditions and are unable to provide electricity or are underpowered. According to these conditions, JXSC specially designed diesel jaw crusher. The diesel-jaw crusher is actually with electric, but the original jaw crusher was added with a diesel engine equipment that a dual-purpose crusher.

JXSC the crushers machine with a non-welded frame has been proved that it has outstanding solid and durable strength. All the alloy casting frame components turn out that with premium quality, wear-resistant property.

The design of pitman and long stoke improves productivity and reduction. A wider feeding material opening increases the volume of insulating material and makes the ore material entering the crushers crushing chamber smoothly. A sharp angle makes the materials flow down speed faster and reduces the wear cost. Besides, the strike force could be stronger thus increase the production efficiency as well as the reduction ratio.

Types of jaw crushers: on the basis of the stone break equipment size and capacity can divide into a heavy and small(mini) portable jaw rock crushers. According to the working principle can be split into single toggle and double toggle jaw rock crushers machine.

A series of jaw stone crushers use compressive and squeezing force for reducing materials. This physical force is created by the two jaw plates, one of which is a movable plate and another is fixed, both of them are made of manganese. A V-shaped cavity, crushing chamber, is formed and the hydraulic discharge gap width of the crushing chamber, we can determine the suited feeding material size and discharging size, the width of top feeding is larger than that of bottom discharging.

Jaw crusher is a heavy-duty machine that crushes hard materials. So its hence muse be robustly constructed. Crusher frame is made from steel or cast iron. The jaws are made of cast steel. The liners are made fromNi-hard, Ni-Cr alloyed cast iron or manganese steel which can replaceable and use to reduce frame wear. The cheek plates are also made from hard alloy steel and installed to the sides of the crushing chamber to protect the frame from wear.

The jaws can be made in smooth or corrugated, but often corrugated. Because the latter crushing the hard and abrasive ores is better. The angle between the jaws is usually less than 26. This is because a large angle will cause the particle to slip which non-crush.

It uses curved plates to avoid the near the discharge of jaw crusher blocking. The bottom of the swinging jaw is concave, and the relative lower part of the fixed jaw is convex. The materials reduction in size when nears the exit. So the material is distributed over a larger area, and the jaws plates wear less.

The type of crushed materials determines how to design the max amplitude of swing of the jaw and the amplitude adjusted by changing the eccentric. The length from 1 to 7 cm depends on the crusher machine size. Jaw crushers are supplied in sizes up to 1,600 mm (gape)1,900 mm (width). For coarse crushing application (closed set~300 mm), capacities range up to 1200 tph.

Jaw crusher parts must have some wear after a period of use, but the easily damaged parts will wear out more. The price of crushing equipment with the same specifications and handling capacity is different in the material of parts.

Guard Plate The guard plate is made of high-quality high manganese steel, which is located between the fixed plate and the movable plate. The whole body is mainly to protect the jaw crusher frame wall.

Toothed Plate Tooth plate is divided into movable and fixed tooth plate, but both is made from high manganese steel casting. In order to prolong its service life, its shape is designed to be symmetrical. That is when one end of the wear can be used to turn the head. The movable and the fixed teeth plate are the main parts for stone crushing. So the movable teeth plate is installed on the movable jaw to protect the movable jaw.

Toggle Plate The toggle plate is a cast iron piece that has been precisely calculated. It is not only a force transmission component but also the safety parts of the crusher. When the crusher falls into the non-crushing material and makes the machine beyond the normal load, the toggle plate will immediately break. Then the crusher machine stops operation, thus avoiding the damage of the whole machine. The toggle plate and the toggle plate spacer adopt the rolling contact model which less attrition under normal use. It just needs smear a layer of grease on the contact surface is ok.

Triangular Belt When the motor transmits power, the triangle belt is connected with the pulley and the grooved pulley of the motor to drive the eccentric shaft and make the moving jaw move back and forth according to the predetermined track.

The tooth plate of the most jaw crushers are made of manganese steel, bearing linings are made of babbitt alloy, sliding blocks are made of carbon steel, toggle plates are made of cast iron, springs are made of 60SiMn. Regular Inspection and maintenance of the machine can extend its service life. In order to reduce customer costs, we will generally be in the purchase of customers are advised to buy some spare parts. Because once the parts need to be replaced, the temporary purchase will take some time. The wait time may cause the entire breakage line to suspend operations, thereby increasing operating costs.

In short, the jaw stone crushers are mainly used for primary crusher, the crushing stone is relatively large. The types of crusher machine's chamber are deep and no dead zone. It improves that the feeding capacity and output. The crushing ratio is large and the product particle size is even. Shim type outlet adjustment device, reliable and convenient, large hydraulic adjustment range that increased the flexibility of the equipment. Simple structure, reliable work and low operation cost. The adjustment range of hydraulic discharge opening is large, which can meet the requirements of different users, low noise and less dust.

Impact crusher for crushing medium-hard stones, and mostly used for secondary crusher. The impact crushers have a big feeding port, high crushing cavity, high material hardness, big block size and little stone powder. Convenient maintenance, economic and reliable, high comprehensive benefit.

jaw plates: how to choose the right one for different types of jaw crushers | fote machinery

The jaw plate is an important part in the jaw crusher equipment, and its service life directly affects the whole jaw crusher equipment. Therefore, you must consider the hardness and toughness of the jaw plate when you want to choose a correct one.

The wear of jaw plate depends on the types of your material and other variables such as material sizes. Too many fines enter the jaw crusher cavity will accelerate the wear speed of jaw plates because the fines fills the valleys which is necessary for the crusher to crush efficiently.

Generally, a jaw crusher finishes the crushing process by squeezing the material between stationary and moving jaw plates. The peaks and valleys of the jaw plates are offset from one another and use the mechanical advantage of leverage to break the rock.

Without this, the crusher has to rely on energy and friction to crush the rock. The compaction will also impose increased loads on the jaw crusher plates as much as five times the normal crushing force.

If the feeding material is over-sized, it also seriously affects the service life. In most applications, the reduction ratio of a jaw crusher is 6 to 1. Exceeding the reduction ratio will generate the crushing forces that break the crushers design limits and affect your overall production and machine performance.

That the jaw plate is severely worn can lead to uneven particle size and low efficiency, which indicates that you have to replace the jaw plates. If you want to choose a correct one, you should consider their different materials according to the purpose and real situation.

High manganese steel contains a relatively high carbon content which plays an important role in wear resistance. In general, the hardness increases with the growth of carbon content. Under non-strong impact conditions, increasing the carbon content is beneficial to improve the wear resistance of steel. And this is why high manganese steel has good deformation hardening ability.

Medium manganese steel has strong hardening ability and stable performance, which creates the function of self-protection when the law plates are subjected to impact and wear. The medium manganese steel jaw plate has achieved good results in the actual production process, and improves service life by 20% compared with that of the high manganese steel jaw plate.

Medium-carbon-low-alloy cast steel is a widely used wear-resistant material at present. Mainly because of its high hardness and suitable toughness, it can resist fatigue spalling caused by repeated extrusion of materials, and shows good wear resistance.

It can also be adjusted by composition and heat treatment to make the hardness and toughness be changed within a large range. That shows high flexibility strong adaption to the requirements of different working conditions.

The hardness of the material-The hardness of the material is also an important factor in choosing the jaw plate. The material hardness determines the toughness and strength requirements of the corresponding jaw plate.

For large jaw crushers, the crushed material is huge-block, which forces the jaw plate to accept strong impact and wear. For that situation, the high manganese steel can give full play to the advantages of good toughness and hardness.

Note: If the flare angle between the moving and fixed jaw plates is too large, it is easy to cause the sliding of the abrasive, deformation and insufficient hardening of the high manganese steel. So sometimes you should adjust the appropriate flare angle during use.

If you need to deal with materials with high hardness such as granite, quartz stone, concrete, etc., the medium manganese steel is the most suitable because of its strong hardening ability. Besides, it has a self-protection mechanism when crushing high hardness materials, which can greatly reduce the wear rate.

Medium and small sized jaw crushers usually bear a low impact load, so under such conditions, medium-carbon-low-alloy steel materials are more suitable. Not only can the disadvantages of high manganese steel difficult to reach the application hardness be avoid, but it also bring good technical and economic benefits.

The angle of Jaw Crusher between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw of jaw crusher moves away from fixed jaw by the pulling force of rod and spring, the products after crushing will be discharged from the outlet of Jaw crusher.

Straight Jaw Plates:Ashows a diagram of a standard type of Blake crusher with regular or straight jaw plates. This type of plate has been the standard from the time of its inception, emulating, in this respect, the straight concaves in the gyratory machine. And it will be noted that the theoretical action in this straight-plate jaw chamber follows quite closely the pattern of the action in the straight-concave gyratory chamber.

Calculations for the jaw crusher chamber are somewhat simpler than in the case of the gyratory because the volumes included between the successive pairs of horizontal lines are rectangular in plan, whereas, in the gyratory we have to deal with annular volumes (actually, a descending spiral, rather than flat rings). But, when the line-of-mean-diameters in the gyratory chamber parallels to a close approximation, at least the centerline of the crusher, the general characteristics of the two crushing chambers, with respect to ratio-of-volume reduction and concomitant reduction in percentage of voids are similar. Crushing angles and throws would of course have to be the same for the comparison to be exact.

There is one readily discernible difference between the two diagrams we are comparing; the drop per stroke in the jaw crusher diagram is noticeably smaller. This difference is most pronounced in the upper part of the chamber. The reason for the difference is two-fold. In the particular machines selected for these diagrams, there is a difference of several degrees of crushing angle in favor of thegyratory; this accounts for the average difference over the full depth of the chambers. Secondly, the motion of the swing jaw, at the top of the crushing chamber is, proportionately, smaller than the movement at the top of the gyratory chamber. The reason for this is that the distance from the top of the crushing chamber to the fulcrum-pointas compared to the total length from discharge-point to fulcrum-point is smaller in the case of the jaw crusher. This is generally true of Blake-type crushers as compared to gyratories except for the vertical swing jaw type, in which the swing jaw is carried up some distance above the top of the stationary jaw.

The close proximity of the fulcrum-point to the receiving opening gives the type of crusher we are considering enormous leverage on large blocks of stone, and the small motion tends to decrease the shocks incidental to gripping and shattering such blocks. From the capacity standpoint, the smaller drop per stroke is compensated for by the fact that the jaw crusher speed, for comparable sizes, is higher than the eccentric-speed of the gyratory.

Non-choking Jaw Plates:When the non-choking concave demonstrated its capabilities in the gyratory crusher, it was only natural that the principle should be applied to the jaw crusher. But, inasmuch as the Blake-type jaw is used very largely for primary breaking, where maximum receiving opening is, more often than not, a controlling factor, the application of non-choking plates to standard machines of this type has one unfavorable aspect, as will be evident from an examination of BStandard Blake jaw crusher non-choking swing jaw plate. This diagram shows the same machine asthe last one considered, except that the swing jaw is fitted with a curved jaw plate.

These non-choking jaw plates have been developed in two styles, reversible and non-reversible. The advantage of the reversible design has been outlined in connection with its application to the gyratory reduction crusher. For both types of jaw plate, the effective receiving opening is reduced, as compared to the standard, straight-plate setup. For the non-reversible plate, this reduction is determined by the actual increase in depth of the plate, resulting from the introduction of the curve. For the reversible plate, it is established by the point where the tangent to the curved surface coincides with the maximum angle of nip for the material being crushed. Similar restrictions were outlined in our discussion of non-choking concaves in gyratory crushers.

Regarding the reversible plate, it should be noted that, while that portion of the chamber above the point of nip does no crushing, it does constitute an active receiving hopper and, as such, is of definite value in minimizing bridging across the receiving opening. For applications which do not require the full rated receiving opening of the crusher, non-choking jaw plates offer a substantial improvement in performance, an improvement comparable to that resulting from the substitution of non-choking concaves in the gyratory crusher. While this is readily apparent from a comparison of the two diagrams we have presented, more concrete evidence is contained in the table of capacity ratings, which gives ratings for both types of jaw plates, for sizes up to, and including, the 6048 machine.
