What is jaw crusher for? Jaw Crusher is a kind of mining equipment used for primary and secondary crushing. It is widely used in medium-sized crushing of various ores and bulk materials in mining, smelting, building materials, highway, railway, water conservancy, and chemical industries.

When used underground, jaw crushers are commonly used in open circuit. This is followed by further size reduction in crushers located on the surface. When the run of mine product is conveyed directly from the mine to the crusher, the feed to the primary crusher passes under a magnet to remove tramp steel collected during the mining operation.

In applications where material is at the top end of allowable feed size to a jaw crusher, the more vertical VGF stroke angle will feed the material at a slower feed rate and allow the crusher to more efficiently process the aggregate without overfilling the crusher feed hopper.
Crushing Process Flow of Stone Production Line Composed of Jaw Crusher The stone is evenly sent from the feeder to the primary jaw crusher for preliminary crushing. The produced coarse material is transported by the conveyor to the cone crusher for fine crushing, and the finely crushed stone is sent to the vibrating screen for screening.
Jaw crushers operate according to the principle of pressure crushing. The raw feed is crushed in the wedge-shaped pit created between the fixed crusher jaw, and the crusher jaw articulated on an eccentric shaft. The feed material is crushed by the elliptic course of movement and transported downwards.
A crusher is choke fed when the chamber is full and there is material above to keep it full. This contrasts with regulated feed, where the flow of material to the crusher is throttled in some manner so that the crusher is never completely filled. Aa particle moves from level to level it drops a greater distance with each movement of the mantle.
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.
A crusher is a tool or machine that is used to reduce the size of a large solid particle to a smaller solid particle. The ore can have a size of up to 400mm. There are many types of crushers but the major ones are the jaw, gyratory and the cone crusher. 2.4.1 Types of Crushers 2.4.1.1 Jaw Crusher
Feeding Jaw Crushers. It is desirable to feed jaw crushers continuously. However, feed is often provided intermittently using front end loaders, shovels or trucks. When the feed rate exceeds the product rate, the condition is known as choke feeding.
Jaw Crushers | Rock Crushers
The crushing process that occurs as feed material passes between the plates of a jaw crusher. It was noted that the breakage process within the crusher operates simultaneously with a

Forced Feed Jaw Crushers. These jaw crushers are ideal for small 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
A comparison of jaw crushers with the same capacity reveals that double-toggle jaw crushers are more expensive than ordinary jaw crushers. For this reason, mostly single-toggle jaw crushers are used in the aggregate sector, while double-toggle jaw crushers are used mostly for crushing very hard and highly abrasive materials.

Additionally, jaw crusher feed should be pre-screened using a grizzly screen prior to crushing to remove material finer than the closed-side setting. Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor.
In applications where material is at the top end of allowable feed size to a jaw crusher, the more vertical VGF stroke angle will feed the material at a slower feed rate and allow the crusher to more efficiently process the aggregate without overfilling the crusher feed hopper. Varying the feeder rpm, preferably with a variable frequency drive
Eastman Jaw crushers are engineered to deliver maximum productivity at the lowest operating costs. It is the best alternative to primary gyratory crushers, process the hard material efficiently. High crushing capability. Jaw crushers are designed to process abrasive hard rock, with aggressively-shaped nip angle, it featurs the crushing ability
Jaw crushers. A jaw crusher is a compression-type of crusher. Material is reduced by squeezing the feed material between a moving piece of steel and a stationary piece. The setting or the space between those two pieces of steel controls the discharge size. The tighter the setting, the smaller the output size and the lower the throughput capacity.

Still using the 32 x 54 Jaw Crusher example, the top size of the feed entering the crushing chamber has to follow the F80 rule that 80% of the top size feed material is smaller than the gape opening. Using the F80 rule with the 32 x 54 Jaw Crusher, the 32” gape opening equals a 26” top sized feed, and with the 6:1 ratio of reduction, the
