What is the use of jaw crusher?

A jaw crusher is a large piece of equipment that’s used in mine and ore processing plants to crush rocks. The equipment was first introduced back in 1858 by inventor Eli Whitey Black who primarily developed machinery used for crushing stone.

What is the efficiency of jaw crusher?

It is well known and taken for granted that the efficiency of energy use by comminution (i.e. breaking, crushing, grinding) equipment is very low, typically less than 10%. Most of the process input power is dissipated as heat and noise and ineffective deformation of the material to be processed and the device itself.

On what principle does a jaw crusher work?

The working principle of jaw crushers is based on the reciprocating movement of the movable jaw that compresses and crushes the rock or ore between itself and the fixed jaw, as the material enters the zone between the jaws.

What is the meaning of jaw crusher?

: a machine for crushing rock or ore between two heavy steel jaws.

What is an impact crusher?

Impact crushers are named after the method they use in reducing larger blocks of rocks to smaller grain sizes. As the name suggests, an impact crusher accelerates the feed material to high speed and then flings the fast-moving rocks against the walls of the crushing chamber and each other.

What is the difference between jaw crusher and impact crusher?

Jaw crusher is mainly used for the process of high hardness materials, mainly for the coarse crushing of ore, while the impact crusher for the treatment of medium hardness and brittleness stones, mainly for the medium crushing and fine crushing of stones.

Which is type of jaw crusher?

There are two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action. A double toggle crusher has two shafts and two toggle plates.

Why is a crushing ratio important?

Crushing efficiency is key to production. Photo by Kevin Yanik. Efficiency can be defined by the ratio of a machine’s work to the energy supplied to the machine. To apply what this means to your crusher, operations produce the exact sizes in the reduction process that their market demands.

What is the work of crusher?

Crushers are machines used to reduce the size of rocks, stones and ore. They are often utilized in aggregates production, construction material recycling and in mining operations.

What is the meaning of crusher?

A crusher is a machine which breaks up solids by pressing them. A rock crusher is a machine designed to take large rocks and reduce them to smaller rocks, gravel, or rock dust.

What is difference between jaw crusher and hammer crusher?

Hammer Crusher is mainly composed of casing, rotor, main shaft, lining plate and striking plate. Hammerhead is the key vulnerable part. Jaw Crusehr is composed of frame, transmission device, adjusting device, tension device, safety device and lubrication system. The jaw plate is the main wearing part.

What does an impact crusher do?

An impact crusher is a machine that uses striking as opposed to pressure to reduce the size of a material. Impact crushers are designated as a primary, secondary, tertiary or quarternary rotor crusher depending on which processing stage the equipment is being utilized.

Why are jaw crushers used in everyday life?

A large number of companies from all around the world use jaw crushers for various crushing applications. The main reason for this is that the jaw crushers offer more benefits and advantages than the other crushing machines. The jaw crushers have the following advantages:

Is there a conflict between jaw crushers and gyratory crushers?

Although their fields of application overlap to a considerable degree (at least in the realm of primary crushing) there is no real conflict between these two machines; one supplements the other and, between them they very effectively cover an imposingly large proportion of the entire field of primary crushing applications.

What should be considered when choosing a crusher?

Usually, in selecting the primary crusher, receiving opening is the prime consideration; admitting of course that capacity must be adequate.

What makes a gyratory crusher an effective slab breaker?

Some rocks of massive formation may contain parallel cleavage planes in certain sections of the deposit. Such material will slab in the crusher just the same as those rocks which were formed in definite layers, or beds. The gyratory crusher by virtue of its annular discharge opening is an effective slab breaker.
