The jaw crusher we produce has a great crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, and economic operation. This machine is widely used by mining, melting, building materials, highway, railway, hydraulic, and chemical sectors for crushing materials whose compressive strength is limited to 320MPa.
This series is mainly applied to middle and fine crushing of medium-hard ores and rocks by metallurgical, mining, chemical, cement, construction, and refractory material and ceramics departments in the industry.This series is most preferably suitable for crushing various soft and hard ores whose compressive strength is limited to 300MPa and whose maximum lumpiness should not be greater than the one required in the technical parameter table.This series works in acurvilinear-motion extrusion manner as follows: the motor drives the belt and pulley to move the movable jaw up and down by way of the eccentric shaft; when the jaw rises, the angle included by the toggle plate and the movable jaw will increase, pushing the movable jaw plate closer to the fixed jaw plate so that materials are crushed or broken into small ones; when the movable jaw moves downward, the angle included by the toggle plate and the movable jaw will decrease, pushing the movable jaw plate away from the fixed jaw plate by the drag link and spring so that crushed materials are discharged from the bottom port of the crushing chamber. As the motor rotates continuously and the movable jaw crushes and discharges materials at some interval, mass production is achieved.
