energy consumption of wet and dry milling

Hence in terms of energy consumption, this process consumes more amount of thermal energy. The length of Kiln in wet process is larger as compared to dry process. Dry Process; Under dry process type, the raw materials are kept dry by utilizing the heat from Raw Mill resulting in poor homogenization which leads to inferior quality of clinker.

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 ().
