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

It was also observed from the experimental results that in order to increase the milling efficiency of a ball mill towards optimum production of material in the desired size class there is a need to correlate the ball size and the feed size distributions

Ball mill feed size 10mm calculate and select ball mill ball size for optimum grinding 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

Ball mill operation ball mills ride on steel tires or supported on both ends by trunnions girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive the prime movers are usually synchronized motors during rotation a portion of the charge is lifted along the inside perimeter

A quick check of the rowland optimum feed size for this ball mill is between 3 and 4 mm operating either circuit you describe will be at least 15 inefficient compared a more conventional ball mill feed size the screen doesnt matter in terms of energy efficiency only more crushing or a small rod mill that will improve the energy efficiency

In all ore dressing and milling operations including flotation cyanidation gravity concentration and amalgamation the working principle is to crush and grind often with rob mill ball mills the ore in order to liberate the minerals in the chemical and process industries grinding is an important step in preparing raw materials for subsequent treatment

Ball mills are among the most variable and effective tools when it comes to size reduction of hard brittle or fibrous materials the variety of grinding modes usable volumes and available grinding tool materials make ball mills the perfect match for a vast range of applications high energy ball mill emax feed material mediumhard hard

This grindability test or bond ball mill work index procedure is used to determine the bond work index of minus six mesh or finer feed ore samples these equation application methods are used to process 12 ore samples in a ball mill using a standard ball charge below describes in general terms the bond work index procedure used by a professional metallurgical testing laboratory if you

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 for the efficient use of rods it is necessary that they operate parallel to the central axis and the body of the mill
