Oct 19, 2006· What it is the optimun speed for a ball mill ? posted in Pyrotechnics: I have done a ball mill, recenly finished, but the motor has too rpms, is too fast for use in a ball mill (the pvc cylinder that i use, left of the shafts). With the motor i will use a 40 mm pulley, because i have a 50 mm driven pulley, in one of my two shafts. In the other side of my shafts there are two 40 mm ...
Apr 08, 1975· A centrifugal ballmill in accordance with claim 1 wherein said first and second milling vessels are mounted opposite each other along a diameter of said turntable on opposite sides of said turntable axis of rotation substantially equidistant therefrom, and on opposite sides of said diameter, said diameter comprising each of said radii.
Critical rotation speed of dry ballmill was studied by experiments and by numerical simulation using Discrete Element Method (DEM). The results carried out by both methods showed good agreement. It has been commonly accepted that the critical rotation speed is a function of a ball radius and a jar diameter.
