There's SAG (Semi-Autogenous Grinding) Mill - perhaps most prominently used in copper mining- which combines features from both autogenous mills and ball mills by using grinding media along with rock feed material. Understanding each type may better help you decide which mill best suits your needs when it comes time to choose one yourself!

Low speed: At low speed, the mass of balls will slide or roll up one over another and will not produce a significant amount of size reduction. High Speed: At high-speed balls are thrown to the cylinder wall due to centrifugal force and no grinding will occur. Normal speed: At Normal speed balls are carried almost to the top of the mill and …

Here's a look at some of the most common types of precision grinding machines from Maximum Advantage-Carolinas. 1. Surface Grinders: A surface grinder consists of an abrasive wheel, a chuck (a workpiece holding device), and a rotary table. 2. Cylindrical Grinders: A cylindrical grinder is used for shaping the outside of a workpiece. 3.

Planetary mills with a single grinding station require a counterweight for balancing purposes. In the Ball Mill PM 100 this counterweight can be adjusted on an inclined guide rail. In this way the different heights of the centers of gravity of differently-sized jars can be compensated in order to avoid disturbing oscillations of the machine.
