Factors Affecting Ball Mill Grinding Efficiency

a) Mill Geometry and Speed Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different length to diameter ratios for a given power rating will yield different materialget price

Quantifying Grinding Efficiency Grinding

EF1 Dry grinding for the same range of work as wet grinding, dry grinding requires 1.3 times as much power as wet grinding. EF2 Open Circuit Grinding when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required on the product produced.get price

Mill (grinding) Wikipedia

OverviewGrinding lawsGrinding machinesTypes of grinding millsSee alsoExternal links

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 (windmill) or water (watermill). Today they are usually powered by electricity. get price
