Rod Mills - 911Metallurgist

The 1st ever built rod mill (2 m in diameter by 4 m long) was to be installed at a mine where a coarser feed was required for shaking tables. Crushing rolls and rod mills were eventually used commonly to prepare feed to shaking tables. Later, rod mills of 2.9 m in diameter by 3.9 m long replaced most roll crushers. Rod Mills cannot be to short:

Rod mills, how they function - Mine Engineer.Com

Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of ...

Rod Mill - an overview ScienceDirect Topics

Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height (or depth) of charge is measured in the same manner as for ball mill. The size of feed particles to a rod mill is coarser than for a ball mill. The usual feed size ranges from 6 to 25 mm.

Industrial Ball Mills for Sale - 911Metallurgist

Intermediate and fine size reduction by grinding is frequently achieved in a ball mill in which the length of the cylindrical shell is usually 1 to 1.5 times the shell diameter. Ball mills of greater length are termed “tube mills,” and when hard pebbles rather than steel balls are used for the grinding media, the mills are known as “pebble mills.’’ In general, ball mills can be ...

Tubular Rod Mills - ScienceDirect

2016-01-01  The grinding action for size reduction of particles is almost similar to ball mills, but in this case the entire length of a rod is responsible for breakage of particles spread along the length of the mill. The breakage occurs more by a cascading action than by cataracting. The rods fall from a height and roll down the mill, so the rods impart an impact force as well as an abrasive action. As ...
