Mechanical ...
Overview of Ball Mills. As shown in the adjacent image, a ball mill is a type grinding machine that uses balls to grind and remove material. It consists of a hollow compartment that rotates along a horizontal or vertical axis. It's called a "ball mill" because it's literally filled with balls. Materials are added to the ball mill, at ...
The rugged RETSCH Hammer Mill HM 200 accepts large feed sizes up to 100 mm which can be reduced to less than mm, depending on the sample properties. The mill is ideally suited for processing large volumes batchwise or continuously which ensures high sample throughput. Thanks to features like rugged design, easy handling and quick cleaning ...

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.
