2. Vertical Ball Mill. A vertical ball mill is a type of ball mill where the barrel is vertical instead of horizontal. It is designed for fine grinding of materials, and it is usually used in laboratory or small-scale production. Vertical ball mills are more energy-efficient than horizontal ball mills and can operate at higher speeds. 3.
