 track jaw crusher,jaw crusher

Our jaw crusher series consist of two types: PEF jaw crusher and PEX series fine jaw crusher. The jaw crusher is characterized by big crushing proportion, even sizedistribution, plain structure, reliable operation, easy maintenance, convenient and economical delivery, etc. The crushing compressive strength of the different kinds of materials are not in excess of 350 Mpa. They are widely used in the departments of mine, smeltery, construction materials, road, railway, irrigation works and chemical industry, etc.

Jaw Crushers Working Theory:

The structure of jaw crusher contains the frame, eccentric shaft, big belt pulley, flywheel, movable jaw, side guard plate, toggle plate, rear seat of toggle plate, modulation gap screw, returning spring, fixed jaw plate and movable jaw plate, etc, among which the toggle plate is used for safety. The working mode of this series jaw crusher is pressing deviously. Its working theory is: The motor drives belt and belt wheel, the eccentric shaft causes the movable jaw to move down and up, forward and backward, the angle between toggle plate and movable jaw becomes bigger when the movable jaw moves up, so that the movable jaw moves toward the fixed jaw, and the materials are pressed, crushed, or cut, as a result, the aim of crushing is accomplished. The angle between toggle plate and movable jaw becomes smaller when the movable jaw moves down, the movable jaw leaves the fixed jaw because of the function of drag link and spring, here the crushed materials are discharged from the bottom hole of crushing chamber. Along with the continuous turning of motor, the movable jaw of crusher moves periodically to crush and discharge materials, so that the mass production is obtained.
