Based on batch grinding method and normalization idea, a conical ball mill is used and a quantitative separation method of grinding characteristics of multicomponent complex ore is proposed. The results show that the feed sizes of polymetallic complex ore have an obvious influence on the particle size distribution of intermediate grinding products in the early stage of grinding. However, the ...

A grinding system in which the crushed product is not classified or returned to the ball mill is called an opencircuit grinding system. Therefore, the circulating load is a crucial parameter to evaluate the running state of the grinding mill. For the secondary ball mill, a common grindingclassification system is shown in Figure 2.

The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill. When ground products present a much coarse or much fine particle size distribution, the separation process ...
