The jaw crusher plays a very important role in the stone production line. It is the main crushing equipment in the stone production line configuration, because the large pieces of material be initially crushed by the jaw crusher before they can be crushed in other parts according to the requirements of the discharge particle size. The equipment is used for secondary crushing. The simple stone production line is mainly composed of vibrating feeder, jaw crusher, vibrating screen, belt conveyor and centralized electric control equipment. To meet the different processing needs of customers, it can be equipped with cone crushing. Machine, dust removal equipment, etc. The jaw crusher can handle materials with a side length of 100-500 mm, and has the advantages of large crushing ratio, and the crushed materials are cubic particles, simple structure, reliable work, easy maintenance, and low operating costs. In the stone production line, the large stones are evenly sent to the jaw crusher by the vibrating feeder through the silo for coarse crushing, and the coarsely crushed stone is sent to the jaw crusher by the belt conveyor for further crushing; the finely crushed stone The belt conveyor is fed into the vibrating screen for screening, and several different specifications of stones are screened out. The stones that meet the particle size requirements are sent to the finished product pile by the finished product belt conveyor, which can meet the different specifications of stone requirements of different customers.
