Mills for indirect firing systems can be run at higher volumes if drying requirements are high. Where drying requirements are low, they can operate down to 1.7-1.8 kg/kg. There are advantages in minimising the mill airflow, thus reducing the primary air level. However mill output and drying capacity can be limited, possibly affecting kiln output.

Tube mills are introduced in the last quarter of 18th century. The low speed mills are known as Tumbling or gravity mills. The earlier version of a tube mill is of a close circuit with a bucket elevator. Now Air swept mills have come up with combined drying & grinding in addition to the elevator which suits best for raw grinding.

In this technical article electrical systems in cement plant will be touched upon. All machines are driven by electric motors. Majority of the motors are 400- 440 volts. A selected few motors of higher ratings are MV motors with 3300, or 6600 or 11000 volts. Most motors are fixed speed and unidirectional motors.
Horo Mill (HM): it is similar to the vertical mill but the roller arrangement differs from VRM. In the ball mill, RP and Combined grinding system separation take place outside the grinding mill, whereas in the VRM separation and grinding take place in one system. The technologies involved in cement can be classified as per the following:
This arrangement required long 6.6 KV cables to various sections. Another option is to locate transformers near load centers i.e., near mills and kiln. See Figures 5 …
