Ball mill is vital equipment in industries viz. mineral dressing, ore processing, fertilizers, food and diary, pharmaceuticals and many others. The present work involves a meticulous study of the effect of the various parameters on the performance of a ball mill. The parameters studied in this work are particle size, number of balls, time of grinding, particle density, and speed of the ball ...
Design Method of Ball Mill by Discrete Element Method The grinding rate of gibbsite in tumbling and rocking ball mills using fins was well correlated with the spe-cific impact energy of the balls calculated from Discrete Element Method simulation. This relationship was successfully used for the scale-up of a rocking ball mill, and the optimum ...
An attempt has been made to develop correlation for the performance of the ball mill by correlating these variables with the grindability on the basis of dimensional analysis approach as well as fractional factorial design method. It is observed that these parameters influence the performance of the ball mill .

Ball Mills · 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.
The ball Grinding Mill discharge material is self-discharge type, which is prone to over-grinding, especially the overflow ball Grinding Mill. Its material is automatically overflowed. When the material level is higher than the discharge port, it automatically discharges, consumes energy and is easy to over-grind.

Nov 18, 2008· 1. Introduction Ball mill is an efficient tool for grinding many materials into fine powder. The ball mill is used to grind many kinds of row materials. There are two ways of grinding: the dry process and the wet process. It can be divided into tubular type and flowing type according to different forms of discharging material.
the feeding material size affects ball mill productivity. In wear-resistant steel ball grinding, in the condition of the same grinding fineness, grain size more coarse, the ball mill production ability is lower Feed particle is, Effect of ball and feed particle size distribution on the
Jun 25, 2004· 1. Introduction. Ball mills have been widely applied in different fields such as the mining, chemical and pharmaceutical industries. One of the most popular ball mills is a tumbling ball mill which consists of a rotating cylindrical drum (with lids) with grinding media such as balls.
Grinding aids for high performance cements Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness. In addition, some products (usually referred to as performance enhancers) provide positive effect on
