Emphasis on crushing and less on grinding. Typical top size: 80 mm if easy to crush, small feedsize. 90 mm is the most common. 100 mm in rare cases; very hard, coarse feed. Coarser ball charges, gives good crushing. capability but: Too porous shorter retention.
Cement mill (Ball Mill) consists mainly of : A rotation steel cylindrical shell supported at both ends on turning /. slide shoe bearings. Liners for protecting the inside surface of the shell. Diaphragms for dividing the mill into two or more compartments. Grinding Balls. Mill cooling system.
From a control point of view, a ball mill grinding circuit represents an interconnected multivariable system with strong interactions among process variables. A typical structure of a closedloop circuit for wet grinding consists of a ball mill, sump and classifier [10, 13, 33, 39] and it is schematically shown in Fig. 4. Fig. 4

3C. Moisture Heating and Cooling Many of us have encountered moisture and moisture related problems, whether we are working with raw, coal or finish grinding mills. When we talk about moisture, we also talk about heating (drying) and cooling mill circuits. Mills themselves generate a lot of heat. For ball mills, 90% of the mill motor power gets converted into heat.
If your Economics permitts for this additional cost, Than you can choose VRM for Cement grinding also. Secondly, The Initial cost is Approx.

Power consumption in ball mill is around 3233 unit/ton, whereas in VRM it will be around 1620 ...
The two key important parameters in mechanical alloying process, namely, milling time (1 and 10 h) and. balltopowder ratio, BPR (5:1 and 15:1) were taken as variable input parameters. The other parameter of milling. speedwas set at 200 rpm in all the samples. Elemental powders of iron (Fe), manganese (Mn), and copper (Cu) were.
over the roof of the mill due to centrifugal action. The critical speed (rpm) is given by: nc = /√d. Where "d" is the internal diameter in meters. Ball mills are normally operated at around 75% of critical. speed, so a mill with diameter 5 meters will turn at around. 14 rpm. ffDESIGN CRITERIA FOR BALL MILL.

A pebble Mill is any Mill in which flint pebbles or porcelain balls are used as the grinding media, and the inside of the cylinder is lined with either porcelain, burrstone, rubber, or some other nonmetallic lines. Steel Ball Mills grind faster due to the use of steel balls, which weigh more than three times as much as a porcelain ball.

Features of Ball Grinding Mill: 1) Ball mill is an efficient tool for grinding many materials into fine powder. 2) The ball mill is used to grind many kinds of mine and other materials, or to select the mine. 3) Ball mill is widely used in building material, and chemical industry. 4) There are two ways of grinding: the dry way and the wet way.
When a ball mill fitted with a diaphragm is overfed, the mill fills up to a certain level, then stops, crushing and discharges any additional feed back through the feed trunnion. Once overfed, it takes from 30 min. to 2 hr. to free itself. Ball mills, therefore, should.
