A mill is a grinder used to grind and blend solid or hard materials into smaller pieces by means of shear, impact and compression methods. Grinding mill machine is an essential part of many industrial processes, there are mainly five types of mills to cover more than 90% materials size-reduction applications.

The Ball Mill, the Pebble Mill and the SAG Mill are 3 of the most popular types of mills on the industrial market. They are primarily used for the Mining industry, but they can also be used in the Chemical & Processing industry which has it's own category page for those listings here: Ball, Pebble, SAG Mills for Chemical Use .
Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These
