> The crushing mechanism of the jaw crusher is that the motor drives the belt and pulley, and the movable jaw moves up and down through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, thus pushing the movable jaw plate closer to the fixed jaw plate. , at the same time, the material is crushed by squeezing, rubbing, grinding and other multiple forms. When the movable jaw moves downward, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw plate leaves the fixed jaw plate under the action of the tie rod and spring. At this time The crushed materials are discharged from the lower opening of the crushing chamber. As the motor continuously rotates, the crusher's movable jaw performs periodic crushing and discharge to achieve mass production. Therefore, the jaw plate is a wearing part of the jaw crusher during use. The jaw plate Wear and tear is a very common phenomenon. This kind of wear appears in the main operating body of the equipment, which undoubtedly directly affects the life and operating efficiency of the equipment.
At present, the most common jaw plate material is water-toughened high manganese steel. Due to work hardening, its hardness can reach from There are unevenness and scratches caused by the cutting of materials. The main factors that affect the wear of the jaw plate include material characteristics, jaw crusher operating parameters, and the material of the jaw plate. After analyzing these key factors, how can we translate our knowledge of the jaw plate into selecting the right materials and using the jaw plate correctly? Huayang Mechanical Engineers recommend that you
On the one hand, strengthen the jaw The service life of the jaw crusher's jaw plate starts from the aspects of design, material selection, assembly, and improvement during use, which can effectively enhance the service life of the jaw crusher's jaw plate, thereby improving the production efficiency of the jaw crusher and reducing production costs. On the other hand, standardize your operations to ensure the machine is running properly. During the production process, the jaw plate of the crusher interacts directly with the material, and the crushing force is very large. Especially when crushing hard materials, it is easy to cause the bolts for installing the jaw plate to vibrate and the nuts to loosen, which intensifies the wear of the jaw plate and produces extreme Loud noise, in severe cases, the jaw plate may fall off or break, causing the equipment to shut down, affecting normal production. In this case, just tightening the bolts and nuts before starting the machine cannot completely solve the problem. It is necessary to analyze the specific problems based on the actual situation on site and find practical ways to solve the problem. For example, a spring anti-loosening and damping device can be used to solve the loosening of the jaw plate during work, thereby extending the service life of the crushing tooth plate and improving work efficiency. The specific method is to use a spring to make a bolt anti-loosening and self-tightening device. This device is worn on the bolt to tighten the nut. The bolt loosening force generated by the huge crushing force is automatically compensated by the spring tension, so the bolt cannot loosen, thus extending the Extend the service life of the jaw plate and improve production efficiency. In short, during use, you can find ways to solve specific problems according to specific situations to prevent the jaw plate from loosening, increased wear, breakage, etc., thereby extending the service life of the jaw plate, reducing costs, and improving work efficiency.
