What is the capacity of the Cone Crusher? What can increase the capacity of the Cone Crusher?
Purpose of Crushers
A crusher is a machine designed to reduce the size of large rocks to smaller rocks, gravel, sand, or rock dust; this is essential for efficient transport of the product via conveyors etc.
Crushing is the first of many stages that lead to separation of the mineral(s) from the waste (gangue) material. Waste material can be discarded or recycled allowing the mineral rich product 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 mineral 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 the feed between two solid surfaces, then by applying sufficient force to bring the surfaces together so that the molecules of the material being crushed 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 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 (if the materials need to be further reduced).
Crusher Types
There are three common crushers used at mining and processing plants:
- Gyratory Crushers
- Jaw Crushers
- Cone Crushers
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 more often used for 2nd, 3rd & 4th stage crushing steps (although not always).
Cone Crusher Components
The main components of a cone crusher include the main shaft, mantle, concaves, cone, eccentric bushing, drive, crown gear, frame, and tramp release mechanism (mechanically or hydraulically actuated).
