zontal and vertical mills. Hammer mill is applied to grind high moisture content brown coal. Horizontal mill, e.g. air-swept tumbling ball mill, is used to grind high ash content or low grindability coal such as lignite. Besides, a vertical mill is normally used for sub-bituminous or bituminous material.  · Autogenous mill is a self-grinding mill which is used in breakage of larger rocks. SAG (Semi-Autogenous Grinding) mill is an autogenous mill which uses grinding balls, it is similar to ball mill but has large diameter and short length. Vertical mill is used in grinding material at smaller particle sizes, which is used after ball mill.
