Jaw crusher is a common equipment in the crushing production line. Because of its advantages of large feed diameter and large crushing ratio, it is often used as a coarse crushing equipment in the crushing production line. However, as the vanguard of the crushing production line, the jaw crusher will inevitably encounter such and other problems during use. Recently, it has received calls from users, reflecting that the jaw plate of the jaw crusher is easily damaged during use.
Indeed, as an important part of the jaw crusher, the quality of the jaw plate directly affects the working efficiency and service life of the jaw crusher. Therefore, when purchasing a jaw crusher, users must look for the powerful manufacturers, don't just pay too much attention to the price, but should take a comprehensive consideration, such as the casting process of the jaw crusher, the selection of materials, etc., then what issues should the user pay attention to when buying a jaw crusher?
Selection of jaw plate
The degree of wear resistance of the jaw plate mainly depends on the hardness and toughness of its casting material. Choose harder materials, the depth of the material is shallow, the deformation of the material is small, and the amount of cutting of the material on the short-distance sliding of the material is also small; the material with good toughness has strong resistance to fracture, which can eliminate brittle fracture during the extrusion and impact process, and improve resistance to fatigue deformation and cracking. These two factors are sometimes contradictory, how to match is a very difficult subject. The preferred material for jaw crusher jaw plate is white cast iron or high manganese steel. White cast iron has higher hardness, better wear resistance, easy source, and low price; the disadvantage is that it is brittle, easy to break, and has a short service life. High manganese steel has strong wear resistance and work hardening properties, which greatly enhances the working time of the jaw plate of the crusher.
The shape of the jaw
The shape of the jaw plate will also affect the service life of the jaw plate. In order to enhance the service life of the jaw plate, the crushing plate of the small and medium-sized crusher is designed in a symmetrical shape, and the head can be adjusted when the lower part is worn out; The jaw plates of the large jaw crusher are designed to be symmetrical to each other, so that the crushing plates can be exchanged for use after wear.
The moving and fixed jaws of the jaw plate
The moving and fixed jaws of the jaw plate of the jaw crusher should be reasonably combined. In the design, the crushing plate of the movable and fixed jaws should be tooth peak to tooth valley. In this way, in addition to the squeezing effect on the material during crushing, it also has a bending effect, and the material is easier to be broken.
