Cement is a material which is used to bind other materials together. Binding means it has an effect of gluing the substances together due to cohesive and adhesive action and then hardens and sets in order to become permanent. Cement is usually not used on its own; it is mixed with other materials called aggregates to produce a …

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.

How cement is made. Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken …
