It can crush materials with middle or less than middle hardness into secondary of fine granularity. Such as, barite, limestone, terrazzo, silica sandstone, coal, coke, gypsum, aluminum sulfate, slag, etc.

There are stone rusher machine driven by motor and small stone crusher driven by diesel engine,see the below photo:

Stone crusher machine Structure

Working Principle

The stone crusher machine  electric motor drives the rotor and the rotor moves, making the hammer rotate in high speed. The materials are crushed in the crusher by the rotated hammer. The end products come out via the strips of the screen under the machine. The size of the granularity can be adjusted by changing the gap among the screen strips. The advantages of the machine are simple in operating, high in productivity, and very low investment cost.
