Toll Milling and Mineral Processing | African Pegmatite

Ball Milling is used in the processing of ceramics, paints, coal, pigments, feldspar, and more. In addition to grinding minerals down, a ball miller is often used to mix or blend materials. It can be used for wet or dry milling. Standard ball milling is performed by rotating the chamber around a horizontal axis. High energy ball milling involves a second, larger chamber in which the smaller ...

nonmetallic mine ball mill

Ball mill is mainly used for grinding in mining metallic minerals and nonmetallic minerals, cement, refractories, chemical, power plant, aluminum,building material, glass, ceramic, steel slag and fly ash, ect. It follows more crushing and less grinding principle to save energy. The feed size to ball mill shall be smaller than 25mm, the output size can be adjusted by revising steel balls ratio.

Grinding

The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 510 cm in diameter but gradually wear out.
