Cement Grinding in Ball Mills and Vortex Layer Devices

The use of ball mills in cement grinding is due to several factors, among which are relatively simple design and high processing rate. However, these machines have certain limitations as well. It is known that only 2 to 20% of the energy is consumed by the grinding proper, while the rest is expanded on overcoming friction, on vibrations and is dissipated as heat.Get price

Method for finish

In recent years the general trend has been towards utilization of roller mills instead of tube mills for finish-grinding cement, e.g. vertical mills in which the grinding rollers roll against a grinding table, or roller presses in which two rollers roll against one another.Get price

Vertical Roller Mills for Finish Grinding

Ball mills, that are commonly used for finish grinding, have high energy demands, consuming up to 30-42 kWh/t clinker depending on the fineness of the cement. Complete replacement of ball mills by vertical roller mills (VRMs) with an integral separator – as opposed to the use of VRMs as pre-grinding to ball mills – is regarded as a breakthrough. Use of VRM in finish grinding Get price

Image

Progress with grinding aids for VRMs

In ball mills, where the grinding time is longer than in a VRM, excessive powder flowability can lead to insufficient or inefficient grinding because the material flows too fast through the mill. In contrast to ball mills, VRMs have a very high internal circulation, a short mill retention time and a huge number of classifying steps that carry the well-dispersed fines out of the mill system.Get price
