Rod Mill Grinding Rods - 911Metallurgist

Unfortunately plant studies on media size versus rod mill performance are rare. The single case that was found was once again from Tennessee Copper. A reduction in rod make-up size from 3 to 2½ inches 76 to 64 mm resulted in: a a 5.4% increase in power draw; b a 7.8% increase in work done as measured by new surface area;

Rod Mills - Mineral Processing and Metallurgy

In standard rod-milling it will be found that rods spread apart at the feed end in the amount of the maximum size of feed entering the mill. In the center peripheral discharge mill the rods are spread at both ends and parallel throughout the length of the mill. This feature results in more space between the rods and thereby lessens the amount of fines produced. Furthermore fines are also ...

Rod Mill Design and Power Draw

Basics of Rod Mill Power Draw. A table of estimates of rod mill power draw is published in Rowland’s work 1982 . Figures in this table are generally slightly low compared to some reported plant data or other manufacturers’ estimates and are based on an empirical formula initially proposed by Bond 1961 designed to cover a wide range of ...

AMIT 135: Lesson 6 Grinding Circuit – Mining Mill Operator ...

AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill. Because of the range of mill sizes available AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit. A diagram of types of AG/SAG ...

Rod Mill - an overview ScienceDirect Topics

The rod mill. In the rod mill high carbon steel rods about 50 mm diameter and extending the whole length of the mill are used in place of balls. This mill gives a very uniform fine product and power consumption is low although it is not suitable for very tough materials and the feed should not exceed about 25 mm in size. It is particularly ...
