There are many factors affecting the grinding process, which can be divided into three categories:
1. Ore properties, including hardness, inlaid particle size, mud content, ore particle size, required fineness of grinding products, etc.;
2. Operating conditions, including grinding machine speed, medium loading system, grinding concentration, classification efficiency and sand return ratio;
3. Types and specifications of the grinding machine.
When designing beneficiation plant, should be properly selected and determined grinding and classification process, device type, size, and the number of suitable mill feed size and speed parameters. In actual operation, these parameters are not easily changed. In production, a certain number of factors (such as grinding, grading concentration, return sand ratio, medium loading system, etc.) are reasonably adjusted according to the nature of the ore, so that the grinding machine can work under suitable conditions.
