Primary air is generally the basic amount of air required for complete combustion of fuel and it depends upon the composition and quantity of fuel required by the fuels will require a different amount of primary air. Primary air is generally provided from the bottom through the Airbox and the fuel is fed either manually or through the screw feeder into the furnace.
The most economical drive to use up to 50 H. P., is a high starting torque motor connected to the pinion shaft by means of a flat or VRope drive. For larger size motors the wound rotor (slip ring) is recommended due to its low current requirement in starting up the ball mill. ... An increase in the mill speed will give a directly proportional ...

A coal mill is also called a coal pulverizer or coal grinder. It is a mechanical device used to grind raw coal into pulverized coal powders. The most used coal mills in cement plants are airswept ball mills and vertical roller mills. At present, most cement plants use coal as the main fuel in the clinker production process.
