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 material retention times, the longer units being utilized for ...

Schellingers calculated ball mill efficiency, in dry or wet ball mill grinding, ranges between 10% and 19%, with the higher figure occurring at the optimal mill loading. In terms of the Brace and Walsh surface free energy of quartz, his results give a ball mill efficiency that is less than 0.5%.
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 ().
5 Ways To Improve Grinding Efficiency Of Ball …
According to Bond (1954), the grinding efficiency of a mill depends on the ball mill diameter, size of the media and mill speed. Ball mills with different length to diameter ratios for a particular power rating will produce different material retention times. The longer units are used for high retention ratios while shorter units are used where overgrinding is a factor to be considered.

Ball mill - Wikipedia
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati
