Jaw crusher plant

Where secondary and tertiary crushers are stacked with a scalping screen between the two, surge and feed control for the tertiary crusher becomes more difficult. The inner cone has a slight circular movement, but does not rotate; the movement is generated by an eccentric arrangement.

The JCRD combination leads to superior precious minerals liberation due to the combined impact crushing and grinding mechanisms.

Installing heavier surfaces may also cause a reduction in screen Jaw crusher plant and unless it is compensated for the reduced action will result in very erratic and inefficient separations regardless of the open area.

Jaw Crushers

Cone crushers and jaw crushers can create rock fill to be used for erosion control and landscaping purposes. Single cylinder hydraulic cone crusher[ edit ] Single cylinder hydraulic cone crusher is mainly composed of main frame, transmission device, eccentric shaft, bowl-shaped bearing, crushing cone, mantle, bowl liner, adjusting device, adjusting sleeve, hydraulic control system, hydraulic safety system, dust-proof ring, feed plate, etc.

Stone Crushing Equipment

As rock enters the top of the cone crusher, it becomes wedged and squeezed between the mantle and the bowl liner or concave. Gyratory crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening.

These production improvements come from speed increases and better crushing chamber designs. In addition, the supporting beneath is designed to provide maximum open area for woven wire cloth.

A cone crusher breaks rock by squeezing the rock between an eccentrically gyrating spindle, which is covered by a wear-resistant mantle, and the enclosing concave hopper, covered by a manganese concave or a bowl liner.

The advance of hydraulic relief systems has greatly reduced downtime and improved the life of these machines. There are two types of impact crushers: Jaw crushers have remained virtually unchanged for sixty years. A great deal of thought has been given to the problem of attaining maximum efficiency in this type of operation.

This motion is useful as it assists in pushing the particles through the crushing chamber. This allows for flexibility in adjustment at each stage for optimum production of the entire system. Jaw crusher is mainly used for the primary crushing process.

Operation of a dodge type jaw crusher Dodge type jaw crusher A jaw crusher uses compressive force for breaking of particle. These plants range from the ground-breaker size, through to larger-scale complete crushing and gravity recovery plants. It is mainly used in mining, chemical industry, road and bridge construction, building, etc.

Conditions are more unfavorable when a decrease in open area is added to this list. This design produces three major principles which all interact when breaking materials using sizer technology.

Except the primary equipment, secondary and tertiary crushing circuit also have impact crusher or cone crusher and vibrating screen or storage bins. The swing jaw closes, i. In the single toggle jaw crushers, the swing jaw is suspended on the eccentric shaft which leads to a much more compact design than that of the double toggle jaw crusher.

The deep scroll tooth pattern: Large pieces of ore are broken once, and then fall to a lower position because they are now smaller where they are broken again.

Since this material is very difficult to handle through a bin gate, it is usual to feed it direct to a specially large preliminary crusher, often of the jaw type, which breaks the ore to a size small enough to enter the normal primary crusher.

HSI's are used in recycling, hard rock and soft materials.


The hard rock mining industry asks for the complete crushing system including hopper, feeder, crushers, and belt conveyor etc. Different crushing circuit involves various crushing machines.

The intermediate bin with the automatic feeder and belt conveyor following it are occasionally omitted, but the practice is not to be recommended, since the discharge of the primary breaker then passes straight to the vibrating screen and cone crusher, with the result that the unavoidable irregularities of feed in the first stage pass on to the second ; moreover, the correct rates of feed for the primary and secondary machines are seldom the same.

Liberty® Jaw Crusher Plant

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
