With the development of economy, China crusher industry grows rapidly under the big demand at home and abroad. After the update of technology, the application scope of crusher become wider, the crusher not only be used in mining industry but also in cement industry, and has played an important role in these industries.Hammer crusher is deep cavity equipment, with long crushing route, which is benefit for materials crushing, crushing process once completed, feeding size reached 125mm~1200mm,can be broken compressive strength is not more than 200Mpa materials, compare with the same kind of products, greater production. The broken way of hammer crusher is curved extrusion type, motor drive belt and pulleys, through eccentric shaft make the movable hammer moves up and down, the inclined angle between toggle plate and movable hammer become large when movable hammer rise, thus promoting the moving hammer plate to close fixed hammer plate, at the same time limestone is squeezed, grind and other multiple broken; the angle between toggle plate and movable hammer become small when movable hammer downward, under the function of draw bar and spring, movable hammer plate leave fixed hammer plate, this moment broken limestone discharged from the mouth, along with the continuous rotation of the motor, movable hammer periodic crushing and discharging, realize batch production of limestone.Hammer crusher relays on the impact power to realize the crushing. During the work, motor drives roller to spinning highly in the crush chamber. Materials were feed from the upper feeding end into the crusher, and were crushed after the hit, impact, cut and grind of the high speed hammer, so as to achieve the Ideal strength of raw material to produce cement.At the present, Fote Heavy Machinery has set up three state level machinery research institutes, and we also produce various kinds of sand production plant, jaw crusher supplier and free service for assembling various kinds of production line....
