The clinker, gypsum, and grinding additives are extracted from silos, dosed, homogenized, and fed into cement mills. Cement mills are tubular ball mills, bicameral, and operate on a closed process. The mill's material is transported to a dynamic separator, separating the fine part (cement) from the coarse part (see Figure 1).

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 ...

Raw coal is conveyed from the storehouse by a belt conveyer. Then it is lifted to the entrance level of a vertical cylindrical mill by a bucket elevator, and an electromagnet is used to remove iron objects from the raw coal. The raw coal is pulverized in the vertical cylindrical mill, and the pulverized coal is lifted to a powder separator by
