PE Series Jaw Crusher Coarse Crushing of Ores / Stones

PE series jaw crushers are mainly applied for coarse primary crushing of minerals or stones by big or middle mining departments. The crushers are workable for the ores or stones, whose compressive strength is not over 350MPa.

PE series jaw crusher is curved extrusion type crusher. Its working principle is that the motor drives the belt and pulley, and the movable jaw move up and down through the eccentric shaft. When the movable jaw moves upside, the angle between the toggle plate and the movable jaw increases, thereby pushing the movable jaw plate close to the fixed jaw plate, and at the same time the materials is crushed and chopped to satisfactory sizes. When the movable jaw moves downside, the angle between the toggle plate and the moving jaw decreases, under the action of the pull rod spring, the moving jaw plate leaves the fixed jaw plate, and the broken material is discharged from the lower month of the crushing chamber. With the continuous rotation of the electric motor, the mechanical jaw undergoes periodic motion to crush and discharge materials, achieving mass production.
