Rod Mill - an overview ScienceDirect Topics

The energy consumed by rod mills could be from 10 to 30% higher than the energy consumed by bar mills and this is for comparable performance. A rod mill is recommended if we want to properly grind large grains, because the ball mill will not attack them as well as rod mills will. View chapter Purchase book

What is a Rod Mill? (with picture) - InfoBloom

Common examples are rod and ball mills, both of which are of the rotary drum type which rely on internal grinding agents to achieve their milling action. Unlike the ball mill which utilizes a large number of hardened steel balls to impart the grinding action, the rod mill uses steel rods

Large Ball Mill Scale-Up Factors to be Studied Relative

Ball mills 5.5 m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills, particularly when the large mills carry 40% by volume ball charges. This paper will explore factors used in scaling up ball mills, showing where the advantages of one factor can possibly be negated by another factor.

Rod Mill Introduction,Rod Mill Working Principle

Rod mills are very similar to ball mills, except they use long rods for grinding media. Rod mill is named like this because the grinding media filled in the cylinder are steel rod. The rods grind the material by tumbling within the mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 ...
