The jaw crusher has large crushing strength and is suitable for coarse crushing or intermediate crushing of various ores and rocks with compressive strength less than 320MPa. It is understood that the components are the core structure of the jaw crusher and play an important role in the work. The following is the structural analysis of the components of the jaw crusher.
Support device: the support device of jaw crusher is mainly used to support eccentric shaft and suspension shaft to fix them on the frame. There are two kinds of supporting devices: sliding shaft and rolling shaft. At present, rolling shaft has been gradually used to replace sliding bearing, which not only reduces friction loss, but also has the advantages of simple maintenance, good lubrication conditions and not easy to oil leakage.
Frame: a rigid frame composed of two longitudinal side walls and two transverse side walls. The frame bears a great impact load in the work, which requires it to have sufficient strength and rigidity. The small and medium-sized ones are generally cast as a whole by cast steel, and the small ones can also be replaced by high-quality cast iron.
Jaw plate: it is used for crushing materials directly. In order to avoid abrasion and improve the service life of jaw plate, Hongxing heavy industry has lining plates on both sides of jaw plate and jaw cavity. The lining plate is made of wear-resistant materials, the small ones are made of white cast iron, and the large ones are made of high manganese steel.
Lining plate: the surface of lining plate is usually cast into wavy or triangular tooth shape, and the tooth peaks and valleys of the two liners are opposite to each other during installation. This kind of lining plate not only exerts extrusion effect on the material, but also applies bending and splitting action, so that the material is easy to be broken.
Eccentric shaft: it is the main part that drives the connecting rod to move up and down. The eccentric shaft of large and medium-sized jaw crushers is usually made of alloy steel, while the small crusher can be made of high-quality carbon steel. The suspension shaft is made of alloy steel or high quality carbon steel.
Thrust plate: connecting connecting rod, moving jaw and frame, which plays the role of transmitting connecting rod force. The thrust plate is usually cast as a whole by cast iron or combined.
