Work principle of rock crusher for mining:

The rotation of the motor through the pulley or coupling, drive shaft and the cone of force in the eccentric sleeve moving around a fixed for rotary movement, so that CS cone crusher in the crushing wall and near and sometimes leave is fixedly arranged on the regulating sleeve rolling white surface, the ore constantly under attack in the crushing cavity, extrusion and bending and crushing ore achieved. At unbreakable foreign body through the crushing chamber or for some reason used rock crushers is overloaded, the spring system of insurance, the mouth of discharge increases, foreign bodies from the crushing chamber is discharged, such as blocking in row ore using cavity cleaning system, so that the discharging continues to increase, so that the foreign body removal of crushing cavity. Under the action of the spring, the gape is automatically reset, the machine returns to normal work.
