Breakers can be divided into categories according to medical Crushing and Mining stone crusher. On gravel mining machine principle adapt to massive mine hard rock crushing double roll crusher, the expected size of its typical granite ≤40mm 90%, the machine can handle the side length of 100 to 500 mm for the following materials, the compressive strength of up to 350 MPa, with a crushing ratio crusher, after crushing the material was cubic particles and so on. Gravel mining machinery refers Layout of particles larger than three millimeters content more than 50% of the total discharged amount of crushing machinery. Motor-driven belt and pulley roll crusher, jaw by the eccentric shaft to move back and forth up and down, when the movable jaw to the fixed jaw plate movable pushing jaw movement to roll crusher, the material is crushed or split pieces. When the action moving jaw and movable jaw plate in the eccentric shaft, spring back, the previously been crushed or split pieces of material from the lower jaw of the discharge port discharge. With the motor continuously rotating motor broken jaw for periodic crushing and waste material, to achieve mass production.
