All indexes of PEC Jaw Crusher on structure and production efficiency present advanced modern technologies. SKE's PEC Jaw Crusher can solve such problems of the existing jaw crushers as low production efficiency, difficult installation and maintenance. At present, PEC Jaw Crusher is the ideal coarse crushing machine at domestic market.

Firstly, the motor drives belt and pulley to make the movable jaw move back and forth, up and down around the eccentric shaft. When the movable jaw pushes the movable jaw plate towards the fixed jaw plate, materials get crushed. When movable jaw and plate move backwards under the action of the eccentric shaft and spring, the materials crushed before would be discharged from the port under the jaw plate. As the motor works continuously, the movable jaw can crush or discharge materials periodically, so that volume production can be achieved.
