Overflow VS Grate Discharge Ball or Mill
The ball mill is designed for the dry comminution of hard materials, especially for the ultrafine range < 10 µm in circuit with an ALPINE ultrafine classifier. Ball mills are giant drums that are filled with between 30 and 40% of their volume with freely moving grinding media, in this case balls.

Grate Discharge Ball Mills have shown 25% to 45% more tonnage ground and a substantial reduction in power consumed per ton of material compared size for size with overflow mills. To illustrate the characteristics of various type mills we have shown the types of discharge for rod mills and ball mills. There are essentially four types of rod mill

Grinding is the process of achieving particle size reduction through attrition and compressive forces at the granular level. The grinding media in a ball mill is typically steel or ceramic balls of varying sizes, depending on the feed size, work index of the ore and the size reduction and distribution required in the discharge.

Wet ball milling is similar to dry ball milling, except that a certain proportion of water or absolute ethanol should be added according to different materials in the grinding process. It is mainly used for materials that will not affect the quality in the presence of water, such as non-ferrous metal ores such as gold, copper and copper.
