Jaw crusher structure overview
The jaw crusher is mainly composed of a fixed body, a rotating body, a safety device, an adjusting device and the like.
1. Fixed body: The main component of the jaw crusher is the frame. There are two manufacturing processes for the frame: medium carbon steel casting frame and medium carbon steel plate welding frame. The welding frame is based on the original casting frame and adds a number of reinforcing ribs, and through the strict quality control and specific process requirements, the same effect as the casting frame is achieved. In order to prevent serious side walls of the rack
The jaw crusher is worn, and the guard plate is installed on the left and right sides of the crushing chamber, which can be replaced at will.
2. Rotating body: It consists of moving parts, eccentric shafts, bearings, pulleys, etc. It is the main part of the jaw crusher transmission and bearing capacity.
a. The moving jaw is composed of moving brackets and movable jaws. The broken moving bracket is made of 35# cast steel and has been quenched and tempered.
b. The eccentric shaft of the boring machine is made of 45# steel and is tempered.
c. The bearing adopts double row radial spherical roller bearing, which has the characteristics of fine adjustment, large bearing capacity and durability.
d. The raft is divided into two kinds of activities and fixed. In order to improve the crushing effect, the surface adopts optimized tooth type. The material adopts ZGMn13 with high hardness, wear resistance and good use effect.
3. Adjustment device: The device is used to adjust the size of the discharge opening and control the discharge size of the jaw crusher. The jaw crusher adjustment mechanism of our factory has two forms: the long wedge type and the top rod gasket type. The adjustment is convenient and flexible, and the stepless adjustment can be realized.
