What is the ball mill

We know ball mill is a piece of equipment for grinding mills materials, and it's widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material. There are many types of grinding media suitable for use in a ball mill, each material having its own specific properties and advantages. Key properties of grinding media are size, density, hardness, and composition.

A ball mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.and works on the principle of impact: size reduction is done by impact as the balls drop from near the top of the shell.

Milling Time of ball mill

The longer a ball mill operates, the smaller the particles will become. They will even reach the sub-micron level if the mill is allowed to run long enough. Always use as little material in the barrel as possible for maximum grinding efficiency. The more of your material you place in the barrel, the more it will cushion the impact of the media, reducing the grinding action. Several small capacity runs are much better than one long run with your barrel packed to capacity with the material you want to powder.

Advantages of the ball mill

Ball milling boasts several advantages over other systems: the cost of installation, power and grinding medium is low; it is suitable for both batch and continuous operation, similarly it is suitable for open as well as closed circuit grinding and is applicable for materials of all degrees of hardness.
