The structure of jaw crusher mainly consists of frame, eccentric shaft, large belt pulley, flywheel, movable jaw, side guard plate, elbow plate, elbow plate back seat, clearance screw, reset spring, fixed jaw plate and movable jaw plate, and the elbow plate also plays an insurance role.

The breaking mode of the series jaw crusher is a flexure extrusion type, the motor drives the belt and the pulley, and the moving jaw moves up and down through the eccentric axis. When the moving jaw rises, the angle between the elbow plate and the movable jaw becomes larger, thus pushing the moving jaw plate closer to the jaw plate, while the material is crushed, rubbed and rolled, and the moving jaw falls down. When the angle between the elbow plate and the movable jaw is smaller, the jaw plate leaves the jaw plate under the action of the pull rod and spring. At this time the broken material is discharged from the lower mouth of the crushing chamber. With the continuous rotation of the motor to crush the motor jaw for periodic crushing and discharging, the mass production is realized.
