    Perfect grinding produces a fine powder termed as raw meal which is preheated and sent to the Kiln. The material is heated to between 12501300 degrees celcius before being dramatically cooled by burst of air in the cooler. This produces the principal ingredient known as Clinker which is the basic material for cement production.
