Analysis of the main structure of the jaw crusher

Jaw crusher, also known as jaw crusher, can crush various materials with compressive strength not exceeding 320 MPa. It has the characteristics of large crushing ratio, uniform output size, simple structure, reliable work, simple maintenance, and economical operating costs. It is widely used in mining, smelting, building materials, highways, railways, water conservancy and chemical industries and many other sectors.

Jaw breaker is mainly composed of fixed body, rotating body, safety device, adjustment device and other parts.

1,Fixed body: The main component is the frame. There are two manufacturing processes for the frame: medium carbon steel casting frame and medium carbon steel welding frame. The welding frame is based on the original casting frame and adds a number of reinforcing ribs, and through strict quality control and specific process requirements, it achieves the same use effect as the casting frame. In order to prevent serious abrasion of the side walls of the frame, guard plates are installed on the left and right sides of the crushing chamber, which can be replaced at will.

2, Rotating body: It is composed of movable jaw, eccentric shaft, bearing, belt pulley, etc. It is the main part of jaw crusher's transmission and bearing capacity.

3, Adjusting device: This device is used to adjust the size of the discharge opening and control the discharge granularity. There are two forms of jaw break adjustment mechanism: the length-lifting wedge type and the ejector pad type. The adjustment is convenient and flexible, and it can realize stepless adjustment.
