Usually, the ball-filling rate is about 40%. The mill balls' size is initially 30–80 cm in diameter but gradually wears away as the ore is ground. In general, the ball mill grinder can be fed either wet or dry. The ball mill machine is classed by electric power rather than diameter and capacity.
The General Function of Ball Mills. A ball mill is a grinder used for grinding and blending materials for mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. Appearance. Ball mills have various designs and functions, ranging from laboratory-scale versions to large industrial models.
The ball mill can process various grinding minerals, non-ferrous metal beneficiation, and new building materials. It is often combined with a spiral classifier to form a closed-circuit ring mill, which has higher fine powder and grinding power. However, wet pan mills are primarily used to grind gold.
