Ball mill circuit classification system performance is considered here first because it provides the basis for subsequent characterization of ball mill breakage efficiency. Major design and operating variables in closed circuit ball milling of a specified feed to a desired product size are summarized in Table 1.

APPROXIMATE CAPACITIES. All ball mills operate on the same principles. One of these principles is that the total weight of the charge in the mill-the sum of the weight of the grinding media, the weight of the material to be ground, and any water in the mill—is a function of the percentage of the volume of the mill it occupies.

The inner layer of ball mill can be made of ceramic or quartz. And choose ceramic ball or quartz ball as grind medium. The whole classify system takes potsherd defending so that the whole production don't touch metal to guarantee the product's purity and prolong the equipments'service time.
