A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
Raw Material Drying-Grinding Drying of moisture in raw materials is required for effective grinding and subsequent handling of raw meal. This is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 320°C.
