Operating principle:
    Reaction crusher is a crushing machine that uses the striking energy to crush the material.When at work, the rotor runs at a high speed with the drive of electric motor.After being crashed by striking of the board hammer of the rotor when the material comes into the impact zone of the board hammer, the material is crashed again after being threw into the reaction unit, and then it is crashed again after being rebound to impact zone of the board hammer.The process is repeated.The material comes into the first, second, and third reaction cavity to be crushed repeatedly, till the material is crushed to the required granularity, and is discharged from the discharge gate.Adjusting the space between reaction frame and rotor can change the material discharging granularity and material shape.

Chracteristics:
    It is applied to the secondary crushing after coarse crusher, can crush the ore of which compressive strength is not more than 320Mpa.It has such advantages as big processing value, fine discharging material, the finished product without innercrack,and etc.
