How to Choose the Right Types of Ball Mill for Your Application

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 smallscale production. Vertical ball mills are more energyefficient than horizontal ball mills and can operate at higher speeds. 3.
