The structure of the jaw crusher can be composed of a fixed body, a rotating body, an adjusting device, a safety device and the like. The main components of the jaw crusher contain flywheel, frame and the tooth plate, also is the most powerful accessories for the crushed material. The following is a detailed introduction:
1. Crushing chamber: The working mechanism of the jaw crusher refers to the fixed jaw and the movable jaw to form the crushing chamber. They are respectively lined with high-manganese steel broken tooth plates, which are respectively fixed on the fixed jaw plate and the movable jaw plate by bolts. In order to improve the crushing effect, the crushing cavity is high and deep, which is beneficial to the crushing effect of the ore.
2. Moving parts: The moving structure is a welded structure, and the inner hole and the groove are precisely processed and tested to ensure safe and reliable operation, and the finite element analysis is used for calculation and verification.
3: frame parts: The frame is subjected to a large impact load during operation, so it should have sufficient strength and rigidity and be calibrated by finite element analysis. It consists of front wall, rear wall, side wall and rail components.
4. bearings: The jaw crusher bearing is a plain bearing cast with babbitt. With the improvement of the technical level of rolling bearing manufacturing, rolling bearings will be used in the jaw crusher in the future. The bearing bush of the main bearing and the connecting rod is overheated and can be cooled by circulating water.
5. the tooth plate: The tooth plate is a part directly in contact with the ore in the jaw crusher. Although the structure is simple, it plays a key role in the productivity, specific energy consumption, product particle size composition and particle size and crushing capacity of the compound pendulum jaw crusher.
