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.

Many different industries have a solid foundation rooted in aggregates. Recognizing the extensive use of these aggregates motivates us to continuously create and improve our rock crushing equipment to help you increase production, decrease maintenance and improve the overall efficiency of your operation. When it comes to quality and efficiency, our rock crushers are perfect for the job.
Primary crushers are first in a typical size reduction operation. Primaries like our Mega-Slam horizontal shaft impactor are commonly used in the aggregates industry to handle large feed sizes.The Grand-Slam HSI is well suited as secondary crusher for aggregate production for a wide range of materials including limestone, frac sand, gravel, stone, and more. Tertiary crushers are commonly used in the aggregates industry for final particle shaping to increase cubicity, and to produce a product size beyond what is capable from a primary or secondary. This stage of crushing is typically accomplished using a vertical shaft impactor or cage mill.
Specialty uses of limestone include the manufacturing of pharmaceuticals, toothpaste, paint, paper, caulking, and glass. Flooring materials, carpet, and plastics all contain finely ground recycled limestone. Common antacids are virtually 100% finely ground limestone. Farmers can reuse limestone to neutralize acidity in their soils, saving money by reducing fertilizer use while improving crop yields.
The 4-Row Cage Mill allows Aglime producers to meet most state Aglime specifications in open circuit. It will economically produce Aglime to any specification for both large and small producers. The 4-Row Cage Mill feed does not have to be dry. Clogging, jamming and plugging are eliminated. Available with capacities as low as 5 TPH up to 100 TPH, the 4-Row Cage Mill produces consistent product quality.
Stedman Machine and Innovative Processing Solutions, an affiliate of Stedman, worked with Duff Quarry Inc. to incorporate two large industrial crushers to handle the size of limestone crushed annually. Their previous machines required a great amount of maintenance, but with Stedman machines, Duff Quarry Inc. spends less time fixing and more time crushing.

The term secondary crushing has become well established and familiar through long usage; it applies to the crushing stage, either single or multiple, which follows immediately after the primary crusher, taking all or a portion of the product of the primary crushing stage as its feed. The term should not be used, as it sometimes is, to designate a particular type or size of crusher because any type and size might conceivably be used for secondary crushing. A very large number of secondary crushers in our present-day plants were originally primary crushers in those same plants. Secondary and second-stage are synonymous, and are equally good and descriptive definitions.
The termtertiary has been used rather extensively in recent years to cover not only third-stage crushers, but in a more general sense to delineate any and all crushers in the reduction and fine-reduction classes; a use which certainly takes liberties with the intent of the word. It is a legitimate term as applied strictly to a third stage of reduction, just as quaternary may be used to designate a fourth stage. Our own preference is to designate these successive reductions as third-stage, fourth-stage, and so on, and to identify the crushers themselves by the titles which usage has conferred upon them.
Reduction-crushers and reduction-crushing, through the same authority of common usage, have been narrowed from the broad scope of their definitions to delineate reductions in the intermediate sizes of product, loosely in the range between 3 and 1 screen sizes. Fine-reduction, in the same fashion, has come to cover the production of sizes in the range below 1, approximately. More recently still, the fine crusher has been introduced to extend the application of the gyratory type down into that borderland between crushing and grinding formerly monopolized by the crushing rolls and the hammermill.
The simplest form of secondary crushing stage involves a single crusher, taking its feed by gravity flow direct from the primary with no interposed scalping separation. This is tantamount to making the over-all reduction in one machine, except of course that there will always be a certain amount of surge capacity between the two crushers. This type of installation has been used in a number of plants, starting with the advent of the power shovel and the large primary crusher, many of which were tacked on to existing plants during the conversion from hand-loading to shovel-loading operation. Probably the most notable of such installations were those of the first jaw crushers of the 84 class. These big machines were designed to operate at rather coarse discharge settings, usually from 10 to 12, and the usual practice was to follow them with gyratory crushers such as the No. 9 (21) or No. 10 (24), the over-all ratio-of-reduction for the two machines being 14 or 15 to 1.
The simple two-crusher, screenless arrangement works out fairly well for the large sizes of primary jaw crushers if the quarry-run rock is reasonably clean, or if any fine material which may be present in the feed is free flowing. The arrangement is not advisable under any circumstances if the setting of the secondary crusher is to be less than about 5 in.; for finer settings than this the fines produced through the two stages are apt to promote a sluggish action in the secondary machine, which might under certain conditions build up to a complete choke in this stage.
So far as the commercial crushed stone plant is concerned the method violates the well established and very desirable principle of scalping off fines between all crushing stages in order to minimize further production of fines by attrition. The safest practice in all cases is to scalp between the primary and secondary stages regardless of the sizes of crushers used or their discharge settings. A plain grizzly is better than nothing; a modern heavy- duty vibrating screen is the ideal heavy-duty scalper.
The capacity of the secondary crushing stage need not necessarily match that of the primary crusher; more often than not it can be substantially less, for reasons outlined in the preceding section. It must of course be adequate to handle its share of the total plant capacity. How much its capacity should exceed the average plant capacity will depend upon how the job is engineered. If the installation is of the simple one-two variety we have just described, and very little surge capacity is provided between the two stages, the capacity of the secondary stage should at least equal that of the primary; otherwise the quarry equipment may be held up at times, waiting on the secondary crushing stage to clear itself. If, on the other hand, an adequate surge is provided to take care of the inevitable fluctuations in feed-rate to the primary, the capacity of the secondary stage may he predicated on requirements of the succeeding stages. This presupposes that the secondary machine or machines will be large enough to eliminate delays due to bridging or blocking of the feed from the primary.
If scalping between the two stages .is resorted to, the rating of the secondary stage may be reduced by whatever amount of undersize material is to be removed from the product of the primary. This can be determined within reasonably close limits by means of the product-gradation curves we have presented. In making this calculation it should be remembered that the scalping screen, regardless of type or size, will not remove all of the undersize. From 85 to 90% efficiency is the usual range, therefore the 10 or 15% undersize which will be carried over must be added to the theoretical tonnage, as figured from the curves, in arriving at the estimated feed to the secondary stage.
Once the required capacity for the secondary stage has been determined, it may be checked against tabulated ratings, at the desired discharge setting, for the type of crusher being considered for the stage. In making this check it should be remembered that capacity tables, while they are prepared on a conservative basis, are predicated upon a uniform rate of feed; and upon the assumption that the crusher is in first-class condition.
If for any reason it is expected that the feed rate will not be uniform, adequate allowance should be made for whatever degree of fluctuation is anticipated, just as was suggested for the primary crusher. Also, inasmuch as it is to be expected that some drop in efficiency of the crushers will occur from time to time because of mechanical conditions, some allowanceshould be made for this, regardless of whether or not the feed rate will be uniform. From 10 to 15% will be sufficient for this in a properly maintained plant.
Surge storage between the primary and secondary stages, while always theoretically desirable, may not always be practicable or economical. The product of the very large sizes of jaw crusher, for example, may be so coarse and slabby that it would be exceedingly difficult to handle through a surge bin or on mechanical feeders of reasonable size and cost. Therefore, where these large jaw crushers comprise the primary stage, it is generally best to consider the two stages as a unit and to match their capacities closely enough so that the material can be kept on the move; providing only a small open surge space between them. Then, if surge storage is desired it may be incorporated in the flow line after the secondary stage. The product of the largest sizes of gyratory crushers can be handled satisfactorily through storage.
