The way of jaw crusher working is bending pressing type. The working principle is: motor drives belt and pulley, make up and down movement through eccentric shaft. When moving jaw ups, the angle between toggle plate and moving jaw becomes larger so as to promote jaw plate to get close to the fixed jaw plate. At the same time materials are crushed or cut pieces to achieve the purpose of crushing. When moving jaw downs, the angle between toggle plate and moving jaw becomes smaller, and the fixed jaw plate leaves the fixed jaw , under the action of bar and spring, ,at this time broken material discharge from the mouth under the crushing chamber. With the continuous rotation of motor, mobile jaw of the crusher makes periodic motion for crushing and discharge materials to achieve mass production.
