### MATERIAL RETENTION TIME IN A BALL MILL & VRM Page 1 of 1

11/08/2010 Re: MATERIAL RETENTION TIME IN A BALL MILL & VRM You could do that by measuring the material flowrate Q [tons/h] through the mill as well as the quantity M [tons] of material that accumulates within the mill. The retention time, also called residence time, is the ratio (M/Q) [h].

### How To Find Ball Mill Retention Time In Case Of Iron Ore Pdf

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

OK mill and the retention time in the mill is shorter, the product will not be heated up as much as in a ball mill. This means that a lower degree of dehydration of the gypsum must be anticipated. This may not be a problem if the gypsum is sufficiently reactive to control the setting reactions, which is normally the case. If in special

### Ball mill Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the

### Everything you need to know about clinker/cement Grinding

-Retention time : < 1 1.5 s . Performance :-Thermal efficiency : 45 60 % (insulated) -Feed moisture : max. 12 15% For instance, in large diameter ball mills, the impact force of the grinding media is so great, that a high material surface unbalance prevails in the mill when grinding all types of clinker, thus requiring a grinding aid at all times. The higher the fineness, the

### Ball Mills an overview ScienceDirect Topics

Milling time in tumbler mills is longer to accomplish the same level of blending achieved in the attrition or vibratory mill, but the overall productivity is substantially greater. Tumbler mills usually are used to pulverize or flake metals, using a grinding aid or lubricant to prevent cold welding agglomeration and to minimize oxidation [23]. Cylindrical Ball Mills differ usually in steel
