Amit 135 lesson 7 ball mills amp circuits mining mill for overflow ball mills the charge should not exceed of the mill volume for grate discharge mills the charge should occupy about of the mill volume bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge he and the radius of the mill r ie

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis the balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size

Tumbling ball mills or ball mills are most widely used in both wet and dry systems in batch and continuous operations and on a small and large scale grinding elements in ball mills travel at different velocities therefore collision force direction and kinetic energy between two or more elements vary greatly within the ball charge

The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency a mill geometry and speed bond 1954 observed grinding efficiency to be a function of ball mill diameter and established empirical relationships for recommended media size and mill speed that take this factor into account as well mills with different

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 14 to 16 rod mills accept feed up to about 50 mm 2 in and produce a product in the size range of 3000 to 270 mm 4 to 35 mesh

In grinding selecting calculate the correct or optimum ball size that allows for the best and optimumideal or target grind size to be achieved by your ball mill is an important thing for a mineral processing engineer aka metallurgist to do often the ball used in ball mills is oversize just in case well this safety factor can cost you much in recovery andor mill liner wear and

Ball mill charging system 202086 mill ball charging systems have undergone little change during the past two decades most operations utilize a locomotiveball car combination to load and haul charges from the ball storage bin to the mill charging boxes or alternatively transport charges to the charging boxes by means of a ball bucket handled by bridge crane
