When the hammer crusher is working, it mainly relies on the impact energy to crush the material. The motor drives the rotor to rotate at a high speed, and at the same time, the material enters the chamber of the crusher from the feed inlet, and the hammer head can impact, shear and tear the material to break it up by means of the high-speed rotating hammer.
The hammer head is the main wear part, and the quality of the hammer head directly affects the crushing efficiency of the crusher. During the working period of the hammer, in addition to being impacted, it is also impacted by the material, so long-term repeated use will damage the working surface of the hammer and change the shape of the surface.
In addition to the wear and tear of the hammer head, there will also be fractures. The main reasons are as follows:
1. When the anchor bolts of the crusher are loose, or the bearings are worn, it will cause the equipment to lose its balance, resulting in relatively large vibration, which will cause the hammer head to break. Therefore, regular inspections are required to ensure that the crusher is running smoothly and well.
2. Hammer crusher is a crushing machine that uses the high-speed impact of the hammer to perform medium and fine crushing operations on materials. The solid waste is fed into the machine from the upper feed inlet, and is immediately broken by the blow, impact, shearing and grinding of the high-speed rotating hammer. If the block of material entering the crusher is too large, there will be a jam phenomenon, which will cause the hammer head to break.
3. During the working period of the hammer, in addition to the impact, it is also impacted by the material, so it is required to have a certain hardness and toughness. If the two conditions cannot be taken into account, either the hammer wears too fast, or causes the hammer to break.
4. There are defects in the hammer casting, such as sand holes, cracks, etc., which can easily cause the hammer to break, so strict flaw detection is required.
