affected by cement dust are likely to be derived due to cement dust. Indeed, the higher percentage of related diseases occurs near the source of pollutant. A relative risk ratio assessment indicates that the exposed subjects are 7.5 and 22.5 times as likely to develop the disease during the follow-up period compared to the unexposed subjects
mill used, i.e. ball mill or vertical roller mill. Typically, the motor of the ball mill consumes about 14 - 15 kWh/ ton of raw mix whereas the VRM motor uses 7 - 8 kWh/ ton. On an overall basis, VRM consumes about 20 % lower specific energy than conventional closed circuit ball mills and is being widely used for raw material and coal grinding ...
Roller mills can typi- cally handle raw materials with an aggregate moisture of 15% while ball mills are limited to about 8%. Ball mills used for drying should be air-swept using air velocity of 3-4M/sec above load. Normally drying is effected by ducting part of the kiln exhaust gas through the mill.

The application of ball mill in cement industry dates back more than 100 years. The ball mill for cement grinding plant is mainly of high fineness, dry grinding method, and the process is mainly of open circuit process and closed circuit process. ... powder concentrator and dust collection equipment. The process is relatively complete.
Ball mills (Fig 1.1) are coming in cement plant areas of raw The large centre openings in the diaphragm and in the outlet grinding, coal grinding and cement grinding which in turn as contribute to an over-all very low pressure drop across the raw mill, coal mill and cement mill.

Cement industry Ball mill Even though ball mills are gradually being replaced by vertical mills and roller presses, they are still the most common grinding systems in today's Cement Plants. The majority of ball mills is driven by Open Gears. Some have central drives and enclosed gear/bearing arrangements.
Figure 4. Typical cement grinding mill A closed circuit consists of three main parts: the ball mill itself, the elevator lifting the mill product to the separator and the separator returning the oversize material to the mill as reject. The separator splits the final (fine) product out of …
