crusher with circular jaws, between which material is being crushed at some point all the time. A conical crushing head gyrates inside a funnel shaped casing open at the top. A crushing head is pivoted at the top. An eccentric drives the bottom end of the shaft. The bottom of the crushing head move towards and away from the wall.

Shaft rotation causes, along with the toggle plate, a compressive action of the moving jaw. A double toggle crusher has, basically, two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of the crusher, while the other is an eccentric shaft that drives both toggle plates.

If crushers that used pressure force is used then it results in unpredictable and even more uneven, jagged shape particles. Therefore, use of VSI crusher results in more cubical and even shapes particles. This is so, because vertical shaft impactor crusher utilizes the velocity force that is applied evenly to the surface and the mass of rock.

Vertical shaft impact crusher These crushers use a high speed rotor that has its axis along the vertical axis. The vertical-shaft impact crusher can be considered a stone pump that can operate like a centrifugal pump. The material is fed through the center of the rotor, where it is augmented to high speeds before being

The rotational energy is fed into the eccentric shaft of the jaw crusher by means of a sheave pulley which usually has multiple V-belt grooves. In addition to turning the pitman, eccentric shaft usually has substantial mass to help maintain rotational inertia as the jaw crushes the material.

The procedure works quite well for this type of crusher but tends to understate power requirements in fine crushers where power rates are typically much higher (upwards from 0.25 KWH/tonne). Because of this, a research program was instituted by Allis-Chalmers Comminution Task Force Committee to break rock in a manner more analogous to that observed within commercial fine crushers.

Introduction. Crushers play an important role in the material handling process for underground mine operations. The main purpose of a crusher is the size reduction of the feed. This size reduction is achieved by applying a force to the material, creating cracks in the material which in the end will cause the material to break into smaller
