The working method of jaw crusher is curved extrusion type. The motor drives the belt and pulley, moves the moving jaw up and down through the eccentric axis. When the moving jaw rises, the Angle between the elbow plate and the moving jaw becomes larger, thus pushing the moving jaw plate closer to the fixed jaw plate.At the same time, the material is crushed, rubbed. When the jaw moves down, the Angle between the elbow plate and the jaw decreases, and the jaw plate leaves the jaw plate under the action of pull rod and spring. At this time, the broken material is discharged from the lower mouth of the crushing cavity.With the motor turning continuously, the motor crushes and discharges the material periodically, realizing the batch production.Make order from long history jaw crusher china supplier with very comptitive price.
