Jaw breaker wide application is in the raw material crushing in fields such as building materials, chemical industry, mine, metallurgy, and jaw breaker is a lamination crushing equipment, and crushing mode is the bending extrusion type, and its theory of operation is: the motor drives the belt and the belt pulley, the movable jaw moves up and down through the eccentric shaft, and the included angle between the toggle plate and the movable jaw is increased when the movable jaw rises, so that the movable jaw is pushed to approach the fixed jaw plate, and meanwhile, the materials are crushed or ground and twisted to achieve the purpose of crushing; when the movable jaw moves downwards, the included angle between the toggle plate and the movable jaw is reduced, the movable jaw leaves the fixed jaw plate under the action of the pull rod and the spring, the crushed material is discharged from the lower opening of the crushing cavity, and the movable jaw of the crusher periodically crushes and discharges the material along with the continuous rotation of the motor, so that the batch production is realized. However, the working chamber of the jaw crusher is generally very deep, so that the height of the jaw crusher body is very high, and the installation is difficult for the position with a low placing space structure.
For the toothed roll crusher, the working principle is that each motor drives a toothed roll which rotates reversely, and a material entering the middle of the two toothed rolls is extruded by the two toothed rolls to be crushed. The distance between the two toothed rollers can be adjusted by means of a spring system or a hydraulic system. When the distance between the two toothed rollers is small, the crushing grain size is small, but the yield of the toothed roller crusher is low. When the distance between the two toothed rollers is large, the crushing granularity is large, the yield of the toothed roller crusher is high, but the crushing effect is poor. Two gear rollers of the gear roller type crusher are arranged in parallel, when the two gear rollers work, the closest distance between the outer edges of the two rollers is a straight line, and the straight line is also the closest working position between the two rollers, so that the working area of the gear rollers is smaller, and the crushing efficiency is low.
