PEW Jaw Crusher (jaw) work crushing jaw crusher structure principle is relatively simple, the aircraft main frame, eccentric shaft, big pulley, flywheel, moving jaw, side guard, elbow board, elbow board seat, gap adjustment screw, reset spring, fixed jaw plate and movable jaw and other components, which also play a role as insurance bracket (when entering the crushing chamber materials that can not be broken, crusher overload protection function bracket play). The broken jaw crusher way for music moving extrusion type, motor-driven belt and pulley, through the eccentric shaft to move up and down movement of the jaw, jaw rises when moving between toggle plate and moving jaw angle becomes larger, thus promoting the movable jaw plate close to the fixed jaw plate, while the material is squeezed, rubbing, grinding, such as multiple broken; when moving jaw down, between toggle plate and moving jaw angle becomes smaller, movable jaw plate under the action of leaving the rod, spring fixed jaw plate, this time has been broken material from the crushing chamber discharge port, with the mobile jaw crusher motor for continuous rotation periodically crushed and nesting, to achieve mass production. Due to the crusher broken material in the itinerary, the jaw plate (working dental plate) in various parts of uneven wear, especially the lower discharge port location near the most serious wear, for generally regarded jaw crusher made up and down symmetrical, the lower will be worn upside down to use in order to prolong its life. sand making machine is SBM Industries for mining, metallurgy, building materials, refractories, cement, ceramics, chemical and other industries specially developed design of the latest products, is currently the most advanced fine pure device because of its unique design allows it to self-strike overcomes broken jaw broken and cone bulky, the shortcomings of poor grain shape, back-breaking solution to iron loss, high production costs less, and is suitable for corundum, silicon carbide, smelting ore, building rubble, sand, broken cement raw materials, and other hard and brittle materials, especially with unique high yield, good grain shape, high efficiency, low energy consumption, broken than big advantage in terms of sand. In metallurgy, mining, building materials, and other industries to provide 5mm or less mineral aggregate for the mill. To improve the mill output provides high-quality raw materials for the mining industry made more crushing and less grinding is best applied technology programs. mobile crusher station can be divided into a tire mobile crushing station and crawler mobile crushing station, where tire mobile crushing station can be divided into standard and closed type. Standard type can be divided into back-breaking mobile crushing plant, cone crusher mobile crushing plant, jaw crusher mobile crushing station, the impact of mobile crushing station, tracked mobile crushing and screening station; closed-type cone crusher can be divided into closed-type mobile crushing station, closed-circuit type of back-breaking mobile crushing station, closed-type shock-breaking mobile crushing station. Crawler mobile crushing plant can be divided into cone crusher crawler mobile crushing plant, jaw crusher crawler mobile crushing plant, impact crusher crawler mobile crushing plant, crawler mobile crushing and screening station.
