Consumption of steel grinding media in mills - A review
According to Moema et al. (2009), in some instances, media wear can constitute up to 40-45% of the total cost of comminution. An estimated consumption of steel grinding media of around 600,000 tons p.a. in the 1980s already gives an indication of the scale of the problem ( Malghan, 1982 ).

Horse mill - Wikipedia
A horse mill is a mill, sometimes used in conjunction with a watermill or windmill, that uses a horse engine as the power source. Any milling process can be powered in this way, but the most frequent use of animal power in horse mills was for grinding grain and pumping water. Other animal engines for powering mills are powered by dogs, donkeys, oxen or camels.

WhatsApp:+8617329420102What Are the Advantages of Wet Grinding vs. Dry Grinding?
Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.
