A stone crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
The working principle of a stone crusher is relatively simple: the stones are crushed by the rotating blades of the machine which are mounted on a rotor. The rotor rotates at a high speed and the stones are thrown against the impact plates mounted on the crushing chamber walls. The stones break on impact with the plates and are further reduced in size by the hammers which are mounted on the rotor.The process of crushing is controlled by a control panel which regulates the speed of the rotor, the feed rate of the stone and the gap between the impact plates and the hammers. The stones are fed into the crusher through a feed hopper which is typically located at the top of the machine.Once the stones are inside the crusher, they are subject to the forces of gravity and the rotating blades of the rotor. The stones are thrown against the impact plates and are crushed into smaller pieces. As the stones pass through the crushing chamber, they are further reduced in size by the hammers which are mounted on the rotor.The crushed stones are then discharged through a discharge chute located at the bottom of the crusher. The size of the stones can be controlled by adjusting the gap between the impact plates and the hammers. The smaller the gap, the smaller the stones that are produced.
