gyratory crusher explained - savree

The process of reducing mined ore for processing is known as comminution, which is defined as the action of reducing a material, especially a mineral ore, to minute particles or fragments; this is normally achieved at mining operations through one or more stages of crushing and milling.

Early mining activities were labour intensive. Ore breakdown occurred via a miners pick, sledgehammer, or drill bit. Until the mid-nineteenth century, most initial ore crushing and sizing continued to be done locally by hand. Later operations were assisted with water powered trip hammers (early-to-middle industrial revolution). The earliest known crushers were hand-held stones, where the weight of the stone increased the force a miner could apply when hammering against a stone anvil. The small volumes of rock and aggregate produced were then typically loaded into sacks for transport by road.

Explosives (gunpowder etc.) were introduced to commercial mining during the industrial revolution; using explosives to mine is referred to as blasting. Blasting came into widespread use for bulk mining in the mid-nineteenth century, followed later by steam shovels. For the first time, new mining techniques and machines began producing ever larger chunks of liberated materials.

Rapid growth in demand over the past century has required considerable upscaling of production tonnages, regardless of the types of ore being mined. To cater for this increase in demand, various crushing and breaking technologies were developed to allow for efficient transport of bulk materials (via conveyors etc.) from the mine to the processing plant.

Today, most mining and quarry operations utilise crushers as part of the front end of the ore beneficiation processes after the ore bed has been liberated by blasting or other techniques. Exceptions include mining of very loose materials such as mineral sands, where this crushing stage is often not needed. Similarly, many coal and lignite beneficiation/washing plants use other technologies such as Bradford Breakers and Mineral Sizers. But for hard rock mining, the use of gyratory crushers, cone crushers, and/or jaw crushers, is the starting point for ore processing.

A crusher is a machine designed to reduce the size of Run of Mine (ROM) large rocks to smaller rocks, gravel, sand, or rock dust; this is essential for efficient transport of the ore via conveyors etc. Crushing is the first of many stages that lead to separation of the ore from the waste (gangue) material. Waste material can be discarded or recycled allowing the ore rich stream to be further processed at the main plant.

Various types of crusher and mineral separator may be employed depending upon the throughput, hardness, and properties of the ore being processed. In all cases, the crushing stage is essentially achieved by transferring a mechanically amplified force (via mechanical advantage) to a material, to breakdown the bonds which hold the material together.

Crushing is achieved by passing ore between two solid surfaces, then by applying sufficient force to bring the surfaces together so that the molecules of the material being treated are separated from (fracture), or, change alignment in relation to (deform), each other.

Crushers are commonly classified by the degree to which they fragment the starting material, with primary and secondary crushers handling coarse materials, and tertiary and quaternary crushers reducing ore particles to finer gradations. Each crusher is designed to work with a certain maximum size of raw material, and often delivers its output to a screening machine (screener), which sorts and directs the product for further processing. In many cases, initial crushing stages are followed by further milling stages using e.g. ball mills etc.

Typically, the initial crushing stage is completed using either gyratory crushers or jaw crushers. It is often the case that there will be only one crusher installed, and this will be referred to as the Primary Crusher. Cone crushers are typically used for 2nd, 3rd & 4th stage crushing steps (although not always).

A primary crusher is designed to receive run-on-mine (ROM) rocks directly from the mines. Gyratory crushers typically crush to reduce the size of aggregate to a maximum of about one-tenth of its original size. Gyratory crushers are always installed vertically orientated.

ROM ore from the mine is typically transferred by haul trucks which discharge into a feed hopper at the upper level; crushed ore is then discharged from the bottom shell assembly. In some cases, a grizzly feeder may be used, and undersize ore can be screened to bypass the crusher (transferred directly to the output conveyor). There is typically also a hydraulic rock breaker to reduce large boulders received from the mine.

The gap between the main shaft and concaves reduces from the top to the bottom of the crusher assembly. The upper concave is lined with hardened steel concave linings and the main shaft is fitted with a mantle liner (sheathe) of similarly hardened material.

Linings are the main wear components of a crusher. Linings wear over time and protect the main casing and shaft from damage. The maintenance strategy for a gyratory crusher will be largely influenced by the rate of wear of the linings, which can be monitored manually (thickness measurements) or by using suitable condition monitoring tools e.g. laser scanning. The liners and mantle are replaced at scheduled intervals or based on the wear rates recorded.

The hydro set system is a hydraulic mechanism which allows the vertical position of the main shaft (and mantle) to be raised and lowered. Changing the position of the mantle changes the gap setting at the outlet of the crusher, and consequently the size of the crushed output. The height of the mantle is often automatically adjusted based upon the torque produced, and has a release mechanism that allows the mantle to drop should the normal workload be exceeded; this is an overload protection feature.

The upper shaft bearing is enclosed within the central spider bushing. This arrangement allows slight oscillation of the upper shaft and limited vertical movement produced by the hydro set. The spider bearing is normally lubricated by grease (manual or automatic).

Crushing action is produced by the oscillation or throw (opening & closing) of the gap between the moving mantle liner, mounted on the central vertical shaft (spindle), and the fixed concave liners mounted on the mainframe (top shell) of the crusher. The mantle and concaves from the working surfaces of the crusher, producing the force required to crush the ore.

Eccentric motion is achieved by the lower eccentric bushing and drive arrangement on the bottom of the main shaft. The input pinion drive countershaft is supported by pinion bearings and powered by an electric motor. An external gearbox or belt drive arrangement reduces the motor speed to approximately 100-200 RPM at the crusher. In some cases, a clutch system may also be used to absorb shocks. The pinion on the countershaft meshes with and turns the eccentric gear drive or crown gear.

The inner surface of the eccentric bushing is machined off-centre from the centre-axis of the crusher. As the eccentric bushing rotates, the lower shaft oscillates in an elliptical orbit around the centreline of the crusher. This action causes the gap between the mantle and concave liners to open and close upon each rotation of the shaft. At the upper end of the mantle this movement is very small, but as the ore falls lower, the throw increases and the crushing force also correspondingly increases.

Crushed ore falls to the bottom shell assembly and is discharged into the crushed ore conveying system for further processing. The lower casing also houses a forced lubrication and hydraulic system, which is critical for the drive arrangement and hydro set mechanism.

Further processing can involve additional crushing stages (secondary, tertiary, quaternary etc.), milling, and other beneficiation steps to suit the ore being processed. It is worth noting that there will often be only a single primary crusher at many mining operations. As such, the primary crusher is a critical and major bottleneck machine for many mining sites, with little, or no bypass opportunities.

gyratory crusher vs. hammer crusher | quarrying & aggregates

Hammer crusher has become a commonly used crushing equipment in quarries and cement plants due to its large capacity and short process. Gyratory crusher is a new type of coarse crushing equipment used in large-scale crushing production lines in mines and quarries. Both are in appearance and principle. It is quite different from the structure.

The gyratory crusher can handle 3000t/h mine and aggregate crushing easily, and the gyratory crusher can even reach 5000t/h or higher (some manufacturers have introduced that its largest model has a capacity of 9000t when it is broken), and its production capacity is usually 2-3 times of jaw crush, especially suitable for large-scale production lines.

The production capacity of hammer crusher is generally not more than 2000t/h. This is mainly due to product design. The hammer crusher has no counterweight wheel design. The hammer crusher with a very large volume is not very safe, which also restricts its large One reason for this, so in terms of production capacity, it cant be compared with the cyclical breakdown.

The gyratory crusher is generally used as a coarse crushing equipment, and the fine crushing equipment and sand making equipment will be configured according to the production requirements. Multi-stage crushing is considered to be more in line with the high-quality finished material process, and the compressive strength and crushing value are better. Well, there are few cracks, and it meets the relevant industry standards and can also meet the requirements of higher-performance concrete.

For small and medium-sized production lines, the hammer crusher has a short process, simple process (compared to multi-stage crushing), and one machine for two purposes. Advantages such as cement or sandstone) are welcomed by some users.

gyratory crusher parts | wear parts for industry | qiming casting

The Qiming Casting primary gyratory crusher parts have the most important role in rock size reduction in mine operations as the crushing process starts from a primary crusher. The highest possible wear life is combined with mechanical reliability through the component life cycle. As the production stops are very expensive for mine operations, the Qiming Casting manganese gyratory crusher wears are easy and quick to install.

Manganese steel mantle wear parts are provided with different shapes, surface profiles, and steel grades. Alloy steel, TIC inserts, and manganese steel concave wear parts are designed for the hardest rock in surface and underground operations.

Our many mantle designs range from smooth one-piece options to large, full-toothed, two-piece, or three-piece solutions. Teeth can be used at almost any level on mantles to improve nip. Our users report that teeth greatly reduce slippage, and improve both production and liner wear life.

For example, crushing some tough materials demands work-hardening manganese steel. But the same liners used for an abrasive, friable ore may wear quickly because there are insufficient impacts to cause the surface to work harden.

Agyratory crusherincludes a solid cone set on a revolving shaft and placed within a hollow body, which has conical or vertical sloping sides. Material is crushed when thecrushingsurfaces approach each other and the crushed products fall through the discharging opening.

The gyratory crusher is composed of transmission, frame, eccentric sleeve, mantle, concave segments, middle frame, beam, prime mover, oil cylinder, hydraulic pressure, pulley, electrical and dry, thin oil lubrication, and other parts. The motor drives the eccentric sleeve to rotate through the belt pulley and the bevel gear, and when the eccentric sleeve rotates, it drives the crushing cone to swing around the center of the crusher. As a result, the surface of the crushing cone is sometimes close to and away from the surface of the fixed cone, so that the materials fed into the crushing cavity are continuously squeezed and bent, and crushed. The crushed material is discharged from the bottom of the crushing cavity by its own weight.

The advantage is that the crushing process is continuously carried out along the circular crushing cavity, so the productivity is high and the power consumption is low, which works smoothly and suitable for crushing flake materials. It can be seen from the particle size distribution curve of the finished product. In the particle size composition of the finished product, the particle size of the material exceeding the width of the discharge port is smaller than that of the jaw crusher, the quantity is also less, and the particle size is relatively uniform. In addition, the raw materials can be poured directly into the feed port from the transportation tool without the need to set up a feeder.

The disadvantages: Complex structure. The price is higher; the maintenance is more difficult, and the repair cost is high; the higher the fuselage increases the cost of the plant, foundation, and other structures.

The gyratory crusher mantle is the major wear part of the gyratory crusher. The mantle which is the movable working surface is pivoted at its top within a spider bearing under the cap of the spider arm assembly while the bottom is gyrated within an eccentric bushing which is powered by the drive assembly.

A mantle for a gyratory crusher having a generally truncated conical shape and having a lower portion that is subjected to greater crushing stress than the upper portion. The upper surface portion has at least one groove which is concentric with the axis of the mantle. During crushing operations, the mantle will grow due to the stresses applied during crushing. This growth will normally result in a bulging of the mantle. The groove in the mantle will permit the mantle to grow thereby reducing bulging. If the mantle is made of two pieces, the groove may be located at the junction of the two pieces.

Different crushed materials need to choose the right material to cast the gyratory mantle. The first choice of material for standard mantles is the Mn14. To further maximize performance and wear life, special designs and high-alloy options are also available.

Standard gyratory crusher concave alloy is manganese, but depending on the feed characteristics a variety of other alloys can be chosen to achieve the best cost per produced ton. The upper concave tiers must withstand high impact forces. The lower tiers require maximum abrasion resistance.

The fewer concave segments you have to handle, the less time it takes to reline your gyratory. We recognize the value of fewer and larger concave segments, and weve manufactured double-height, double-width, and double-height & width concaves for many satisfied customers.

The benefit to you is greater efficiency when ordering and replacing parts. In general, larger parts cost less per pound. There are also fewer seams, an important consideration since these are often the areas of most severe wear. In addition, fewer joints mean less backing material.

General-purpose concaves with uniform thickness often wear poorly because the wear is not uniform from application to application. We have found that by increasing thickness, we can often double or triple wear life. All our concaves have side grooves for spacer or keeper dowels.

gyratory crushers - sandrock mining

Sandrock Mining Gyratory crushers are frequently used in the primary crushing stage and a little less often in the secondary stage.Gyratory crushers have an oscillating shaft. The material is reduced in a crushing cavity, between an external fixed element (bowl liner) and an internal moving element (mantle) mounted on the oscillating shaft assembly.The fragmentation of the material results from the continuous compression that takes place between the liners around the chamber. An additional crushing effect occurs between the compressed particles, resulting in less wear of the liners.The gyratory crushers are equipped with a hydraulic setting adjustment system, which makes it possible to regulate the gradation of the crushed material.

Sandrock Mining is a growing company with years of experience in produce and supply of wear parts such as the Bowl Liner, Mantle, Jaw Plate, Cheek Plate, Hammer, Frame, Linerand spare parts such as Bushing, Shafts, Gears, and so on.
