In the concentrator, the grinding stage is an important part of the investment of a large amount of money and energy consumption, the grinding process controls the particle size changes of the entire beneficiation process, which has a great impact on the productivity and recovery of the concentrator, so how to reduce the cost and improve the productivity of the ball mill in a certain grinding fineness standard is quite a concern.

In the choice of grinding methods, there are two kinds of open-circuit grinding and closed-circuit grinding. What are the characteristics of these two grinding methods? Which grinding method can realize the utilization of grinding equipment and improve productivity?

Ways and Characteristics of Open-circuit Grinding and Closed-circuit Grinding

Grinding: refers to the grinding operation, the material into the ball mill after a grinding discharge, directly into the next mill or the next process.

Grinding advantages: is the production process is relatively simple, and the cost of investment is low. Its disadvantage is that it has a low production efficiency and produces a large energy consumption during production.
