Several factors that affect the crushing ability of the crusher parts mainly include: stone hardness, stone viscosity and humidity, final discharge particle size, stone composition, and the quality of the crusher itself. 1. The hardness of the stone: the harder the stone, the more difficult it is to break, the more serious the wear on the equipment, the slower the crushing speed, and the smaller the crushing capacity. 2. The viscosity and humidity of the material: that is, when the material contains a large amount of water, the material is easy to adhere in the crusher, and it is also easy to block during the feeding and conveying process, resulting in a reduction in the crushing capacity. The higher the viscosity, the lower the crushing ability. 3. Final discharge particle size: The smaller the particle size required for the final crushed stone, the slower the crushing speed and the smaller the final impact on the crushing capacity. 4. The basic composition of the ston
