Maintenance Work of Spare Parts of Hammer Crusher

The maintenance work for the spare parts of the hammer crusher is very important to improve the production efficiency and the performance of the hammer crusher. The maintenance work of the spare parts of the hammer crusher can be divided into the following aspects.
The first is the maintenance for the hammerhead of the hammer crusher. The hammerhead is the main working part for the hammer crusher. The production capacity of the whole crusher is related to the shape, quality and the material of the hammerhead. In particular, the shape has great impact on the uniform distribution of the quality and the full advantage of the materials. The hammer crusher is suitable for the cement, chemical, electric power, metallurgy and other departments. Therefore, the shape of the hammerhead can be roughly divided into light type, medium type and the heavy type.
During the operation, the hammerhead subjects to the dual role, namely the shock and the impact of the materials. After the long-term repeated use, the working face of the hammerhead will be damaged so that the surface shape changes. Therefore, we need to frequently replace the hammerhead. The factors affecting the service life of the hammerhead include the structural design and the quality of the hammerhead, the technical parameters of the hammer crusher, the hardness and the lumpiness of materials, and the inner adjustment of the gap of the hammer crusher.
In order to improve the abrasion resistance of the hammer crusher, the material selection of the hammerhead is a key issue. However, the choice of the materials depends on the working conditions and requirements of the working parts. Therefore, if the hammer crusher is used to crush the limestone and other materials with medium hardness, the hammer head is generally made of the high-carbon steel or the high manganese low alloy steel. Sometimes, the working surface will be coated the carbide. Some hammerhead is made of the high chromium castiron whose wear resistance is several times greater than the wear resistance of the high manganese steel.
