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, the expected size of its typical granite ≤40mm accounted for 90 percent of the roll crusher, 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, 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.
