In the last decade vertical mills have taken an increasing share of the cement milling market, not least because the specific power consumption of vertical mills is about 30% less than that of ball mills and for finely ground cement less still. The vertical mill has a proven track record in grinding blastfurnace slag, where it has the additional advantage of being a much more effective drier

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. The

Jul 07 2017 · The advantages of ball and race mill are as follows Lower capital cost Lower electricity power consumption Lower workspace required Lower weight. However in ball and race mill there is greater wear as compared to other coal pulverizers. The usage of pulverized coal as a fuel has now become the standard method of firing in many huge boilers.

Next we consider the ball mill (rock and ball) cases with smaller cutoffs. The base case is our standard mill with a cutoff of 5 mm for the rock size. This is compared to cases that are same except for the cutoff being reduced to 2 and 1 mm, respectively. The specific power draw curves are shown in Fig. 14b.

Roller grinding mills and ball mills grind the mixture to a fine powder at the same time as drying it, before it is conveyed to the raw meal silos for further homogenisation. Step #4 The burning of the raw meal at approx. 1,450°C is carried out in Lepol or preheater kilns that work by varying methods, the main difference being in the preparation and preheating of the kiln feed.
