Understanding the Process of Comminution

Commission is a process of breaking down or crushing materials into smaller particles, typically for the purpose of liberating valuable minerals or metals. It involves the use of mechanical forces, such as impact, abrasion, and grinding, to break down the material into smaller pieces. The process can be used to treat a wide range of materials, including ores, coal, and other minerals.

There are several different methods of comminution, including:

1. Crushing: This involves breaking down large rocks or ore into smaller pieces using a crusher.
2. Grinding: This involves breaking down materials into smaller particles using a grinder or mill.
3. Pulverizing: This involves breaking down materials into very fine particles using a pulverizer or grinder.
4. Impact crushing: This involves breaking down materials using impact, such as with a hammer or an impactor.
5. Ball milling: This involves breaking down materials using balls in a rotating mill.
6. Rod milling: This involves breaking down materials using rods in a rotating mill.
7. Vertical roller milling: This involves breaking down materials using a vertical roller mill.
8. Stirred milling: This involves breaking down materials using a stirred mill.

The goal of comminution is to break down the material into smaller particles that can be more easily separated from one another, allowing for the recovery of valuable minerals or metals. The process is an important step in many mining and mineral processing operations, and it can also be used in other industries, such as cement production and waste management.
