The hardness of the ore, which reflects the mineral composition of the ore itself and its physical and mechanical properties. The ore is dense, the crystal is small, and the ore with high hardness is more difficult to grind. Therefore, in the process of grinding, such ore requires a long grinding time to ensure the required fineness of grinding, but generally affects the processing capacity of the mill. The ore with a small hardness or a haircut is easy to be ground, and the processing capacity per unit volume of the mill is also high.
Ore hardness is an unchangeable factor. In the production, we should take a positive attitude towards the ore with a higher hardness, such as through experiments to find the most suitable operating conditions such as the concentration of ore discharge and the amount of sand returned. It is required to reduce the ore particle size from the crushing system as much as possible, and find the optimal steel ball ratio under the condition of stable particle size conditions.Spherical Bevel Gear,Hypoid Bevel Spiral Pinion Gear,Hypoid Bevel Gears,Industrial Bevel Gears
