Rod Mills - SolidsWiki

Rod Mills are similar with the Ball Mills xcept 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.

Development appli ion and operating results of the center

A rod mill differs from a ball mill in that the comparatively rigid grinding media operate in a relatively fixed path and reduction results fram line rather than point contact between grinding surfaces. Conventional rod mills are either high or law discharge. In the high discharge mill the discharge trunnion. is. the same size or only slightly

How to Handle the Charge Volume of a Ball Mill or Rod Mill

Ball mill charge becomes measurably swollen only when there is a buildup of large unground material in the ball mill or when the density of the pulp in a wet mill is extremely high. Although these conditions are seldom encountered it is recommended that ball mills be ground out prior to shutdown for measurement of the charge level.
