The PE and PEX series jaw crushers are powere by a motor. through the motor pulley, the eccentric shaft is driven by the V-belt and the groove wheel. So that the movable jaw can reciprocate according to a predetermine trajectory. The materials in the crushing cavity compose of side guards are crusher, and the finished materials are discharge through the lower discharge port.
The crushing method of the jaw crusher is a curve extrusion type. The motor drives the belt and pulley, and the movable jaw moves up and down through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger. thereby pushing the movable jaw plate toward The fixe jaw is approaching, and at the same time, the material is crusher by multiple crushing. such as squeezing, rubbing, and grinding. When the movable jaw descends, the angle between the toggle plate and the movable jaw becomes smaller. And the movable jaw leaves the fixe jaw under the action of the pull rod and the spring.
At this time, the PE jaw crusher machine materials are discharge from the lower mouth of the crushing cavity. With the continuous rotation of the motor, the crushing mobile jaw is periodically crusher and discharge to realize mass production.
