The crushing roller is the main working mechanism of the crusher. It is composed of a shaft, a hub and a roller skin. The degree of wear of the roller skin has a great influence on the working efficiency of the roller crusher. Only when the roller skin is in good condition can the crusher achieve higher production capacity. It is precisely because of the importance of the roller skin that it is of great significance to understand the factors that affect the wear of the roller skin and to correctly repair the roller skin. The factors that affect the wear of the roller skin mainly include the hardness and particle size of the crushed materials, the material of the roller skin, the size and surface shape of the roller, and the ore feeding method, etc. The roller skin of the counter-roller crusher is affected by the comprehensive forces such as material impact and self-weight during use, and is easily worn. The wear of the roller skin will not only affect the work efficiency, but also cause harm to the crusher itself. The matching ratio of the contact surface between the roller skin and the roller body should be above %, which is a hard fit. Once a matching gap occurs due to wear, the wear will further increase under the continuous erosion of materials, putting the crusher in a hidden danger state. At the same time, after wear occurs, the roller body will be injured, the roller skin will crack and partially fall off, and the fastening bolts will be deformed or broken, making it difficult to disassemble when the roller skin is replaced again. Therefore, choosing a roller skin with good wear resistance is crucial to improving the working efficiency of the roller crusher. When choosing a double-roller crusher, the roller skin must be thickened and heavier.
