Reduction of grinding mill
Ball Mills - Mineral Processing & Metallurgy
The basic principle for rod grinding is reduction by line contact between rods extending the full length of the mill, resulting in selective grinding carried out on the largest particle sizes. This results in a minimum production of extreme fines or slimes and more effective grinding work as compared with a ball mill.

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

Size Reduction | Mill (Grinding) | Applied And ...
A greater size reduction ratio can be obtained in fine crushers than in coarse crushers Types of grinding Grinding may be carried out either wet or dry. wet grinding is generally applicable only with low speed mills. The advantages of wet grinding are: The power consumption is reduced by about 2030 per cent. The capacity of the plant is increased.
Process engineering: Particle size reduction techniques ...
Wet grinding often takes place in ball, pebble or rod mills. The efficiency of wet grinding can be higher than that for dry grinding, but wear of equipment is also higher [2]. Most size-reduction equipment is subject to heavy wear and therefore parts, such as casing liners, hammers and jaws, are designed for relatively easy replacement.
