A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, and ceramics. It works on the principle of impact and friction between rotating balls and the powder materials. The ball mill consists of a rotating drum and a hollow cylinder filled with grinding media, typically ...

Here we will give you a complete guide on what is a ball mill vs SAG mill, how they are different, and how they are used. Let's get started! Operating Principle. The operating principle difference between a ball mill and a SAG mill is their specific energy consumption. Ball mills use an induced storage mechanism to grind materials.

SAG mills have a power higher than 10 MW. Even ball mills have a power larger than 10 MW. For this reason, they have an important impact in energy consumption and in the operation of the power distribution system. Figure 1. Picture of a typical GMD system for a SAG mill Figure 2 presents the power circuit of a cycloconverter fed synchronous motor.
