A grain crusher is designed to crush grain using various mechanical methods, including different mechanisms that can achieve reciprocating motion. Here are three such mechanisms: Crank and Slider Mechanism: This mechanism uses a rotating crank connected to a slider. As the crank rotates, it moves the slider back and forth in a linear path.

A jaw or toggle crusher consists of a set of vertical jaws, one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism. The jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed progressively smaller and smaller as it travels downward until it ...

In roll crushers, the material is pulled between two counter-rotating rolls which exert a shear force on it. The material breaks and reduces in size due to this force. This kind of crushing works better for materials that have a layered or flat structure because the shear forces can easily split the material along the weak planes.

A crusher is a machine that reduces large rocks into smaller rocks, gravel, or rock dust. Crushers are mainly used in the mining and construction industries, where they are used to break down very large rocks and boulders into smaller pieces. Crushers are also commonly used for jobs like breaking up asphalt for roadwork or demolition projects.

The mechanism of double-toggle jaw crushers allows applying only pressure on the material. 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 ...
