Ball size as initial charge commercial ball sizes 10 150 mm number size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge for the initial chargin of a mill coghill and devaney 1937 defined the ball size as a function of the top size of the feed ie dv 040
More balls with small size results in fine powder as a thumb rule powder to be milled should be taken as 25 of total ball weight if the quantity of charge is very less then milling balls will
The first problem will ball mills is that we cannot see what is occurring in the mill the other problem is that many of the independent variables are nonlinear or have paradoxical effects on the end results in ball milling of dry solids the main independent variables are mill diameter mill speed media size solids loading and residence time

Dont know about the roller but the optimum speed for a ball mill depends on the size of the jar and media theres a formula for calculating this i dont have it around but it is in lloyds book however for a 6 jar and 34 media it should be appr 75rpm it decreases with jar size and increases slightly with media size
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
Sep 15 2017 these ball mills are often called planetary ball mills the rotating drums are not usually detachable the material is poured into the top and the cap is replaced like a kitchen blender like all ball mills the speed and ball size have an effect on how the vertical ball mill works
