Stone crushers are also called rock breakers. They are quite popular machines in the mining machinery industry.
Stone crushers like jaw crusher, impact rusher, cone crusher etc are famous among customers because of the countless advantages such as: low construction cost; high crushing efficiency; fine crushing and rough grinding functions; be able to crush medium hard and extra-hard materials; simple to operate, maintain and install etc.

So how do stone crushers complete the crushing process? The answer is:
1.Materials enter the crusher via the feed hopper and are divided to two parts. Some enter the high speed spinning impellor through the distributor and the accelerated speed can be a hundred times of the gravitational acceleration.
2.Then the materials are thrown out from three runners at the speed of 60-70m/s and impact the falling materials from the distributor. Then they come to the lining of the inner cavity and get bounced by the material liner to the upper end of the whirling motion cavity. Then they change the direction to move down.
3.The materials cast from the impellor form a continuous material curtain. In this case, the materials can experience two or more times of impacting and grinding processes. The crushed materials are discharged from the bottom hole.
In the whole crushing process, the materials hit each other without touching the metal components directly. They meet the material lining in order to reduce the pollution and prolong the service life of the machine. The advanced air flow in the whirling motion cavity can effectively reduce the dust pollution.
