Advantages of operating philosophy of a rod mill

mill (grinding) 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 . rod mill block varioblock rana udyogtherefore, the rod mill blocks operating in the highspeed range are of a particularly rugged design. our rod mill blocks feature product speeds up to 100 m/s (designed for 1 m/s) through optimized mechanisms. low gear speeds compared to roll speeds. roll forces and roll torques designed for lowamit 5 lesson 3 particle size distribution mininggatesgaudinschumann model.
