Figure shows a flow sheet where the rod mill is in open circuit and the ball mill is in closed circuit with a classifier. This is a normal setup as the primary function of a rod mill is to provide a uniform sized feed to the ball mill. Figure shows that the rod mill product is classified and a more uniform feed size is, therefore, discharged to the ball mill whose primary function is ...

Calculation For Speed Of Ball Mill Of Rpm From Nigeria. Calculation For Speed Of Ball Mill Of 21 Rpm Ball Mill. Calculations: the critical speed of ball mill is given by, where r = radius of ball mill; r = radius of ball. for r = 1000 mm and r = 50 mm, n c = rpm. but the mill is operated at a speed of 15 rpm. therefore, the mill is operated at 100 x 15/ = % of critical speed.

In this paper, the milling parameters of high energy ball mill (Fritsch Pulverisette 7) like vial geometry, number and size of balls and speed of the mill were modelled and discussed. Simulations through discrete element method (DEM) provide correlation between the milling parameters. A mathematical model is used to improve and develop this process.
