A roller mill is a type of grinding machine used to crush or grind various materials, particularly grains like wheat and corn. It operates by passing the material between two or more cylindrical rollers, which apply pressure to break down the particles. This process is efficient and helps produce finer flour or meal compared to traditional grinding methods. Roller mills are commonly used in the food industry, especially in the production of flour for baking. They can also be found in other industries, such as the production of animal feed and in the processing of minerals. The design of a roller mill allows for precise control over the size of the final product.
