What causes the cracking of the jaw crusher frame

The frame of the jaw crusher is mainly divided into two types: a welded frame and a cast steel frame. These two types of frames each have their own advantages. Although the welding frame has certain advantages in terms of cost performance, there will also be some fatal failures in the welding frame during the production process, that is, the welding frame of the jaw crusher is in production. In the process of cracking, the frame is the first line of defense for the entire equipment of the jaw crusher, and its quality directly determines the service life of the entire equipment. So what caused the cracking of the welding frame of the jaw crusher?

Generally speaking, the main reason for the cracking of the welding frame is the welding process, of course, this is not the only factor. Because of the welding process, the cracking of the jaw crusher frame is often caused by some small manufacturers whose technical level is not up to standard, that is, black workshops. When these manufacturers produce jaw crushers, because the factory conditions are not up to standard, they often work outdoors. If the temperature is below zero in winter, the weld metal cools quickly during low-temperature welding, so the hardening tendency is greater than that of low-carbon steel. The tendency to crack also increases. The second point is that the hardware facilities of these small manufacturers cannot keep up. Before welding, the welding rods have not been strictly dried, and the hydrogen elimination measures have not been taken after the frame is formed. These factors have led to the unqualified welding frame, which is also source of hidden dangers. These are several reasons for the cracking of the frame in the welding process. In addition to the manufacturing process, there are also some accessories, such as the toggle plate of the jaw crusher. At this time, the strong impact force of the machine will act on the machine itself, and the strong vibration force will also cause the frame to crack, and the jaw plate is not fixed well, and it moves inside the machine cavity during the production process, moving up and down for a long time. This is also what causes the mecha to crack.

To sum up, when buying a jaw crusher, you should choose a regular manufacturer, and don’t choose those small manufacturers for cheap. In this way, it is still your own interests that cause problems and damage to the machine. When you buy a jaw crusher, you must first check this manufacturer Only in this way can we buy a suitable high-quality jaw crusher.
