The Cement Manufacturing Process. India is the second-largest producer of cement in the world producing 502 million tonnes of cement per year. There are 210 large cement plants producing 410 million tonnes of cement every year and 350 mini cement plants producing 92 million tonnes of cement per year.

In cement plants, proper specification and supply of AC induction motors is critical to project schedules and providing efficient production. This paper focuses on the selection of AC induction motors for cement mill applications, with reference to fan, kiln and vertical mill applications. The criteria for motor selection includes:

Manufacturing - the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the ...

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.

The only common feature in all cement production plants is the difficulty of grinding the source material as the material is hard enough and has high abrasiveness. That is why high quality grinding balls with high hardness over the entire section are used during grinding materials in tube mills in this industry.
