The main advantages of compound pendulum jaw crusher are: light weight, simple, reasonable configuration, compact structure, relatively good filling rate of the crushing cavity and even crushing of material.

The material will be discharged from the bottom of the movable jaw if it is broken to reasonable particle size. Therefore, the production efficiency is high . And since the block material rolls up and down the bottom of the movable jaw, the finished product features good shape and high qualified rate.

Three dimensional model is foundation work of jaw crusher parts design , which is directly related to the follow-up work . The correct model refers to the accurate analysis of the crusher parts and three-dimensional assembly .Crusher frame design is concerned with successful, reasonable installation of whole crusher spare parts. Because jaw crusher is under a lot of impact in the work, the workload is very big. To compound pendulum jaw crusher, we often use ZG35 as casting material.

Jaw crusher is equipped with double row spherical roller bearing on both ends, with the inner race fitting the eccentric shaft. The main bearing part is designed in the lateral of eccentric shaft neck, and the outer frame is connected with the hole of the frame, fixed on the frame with bolt. The movable jaw plate is fixed on the head. Dismantling lining plate is convenient, and the plate may be fixed at any time, and the center of the movable jaw can be adjusted to approximate the rotary center, ensuring the smooth operation of the machine in the process.
