A grinding mill is a tool that is designed to break a solid material into smaller pieces. There are many different types of grinding mills and many types of materials processed in them. Small mills can be powered by hand, such as a mortar and pestle or a pepper grinder. Large grinding mills were usually powered by working animals, wind or water in the past. In the 2000s, most large grinding ...
