M = tonnage of ore in mill discharge. and Ds Do and Dm are the liquid-to-solid ratios of the sand overflow and classifier feed at the points where they leave or enter the classifier. Then circulating load ratio = (Do-Dm)/ (Dm-Ds) (8) And circulating load tonnage = F (Do-Dm)/ (Dm-Ds) (9)

  • Mill (grinding)Wikipedia

    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 (e.g. via a hand crank) working animal (e.g. horse mill) wind or water ().
