MAIN SUPPLIERS .f24 INTRODUCTION The roller press is a relatively new development in the cement manufacturing process. This efficient comminution machine is applied mainly for clinker but is also used for raw material and slag. The size reduction of the material takes place under high pressure between two rotating rollers.

To prevent coal entering in to the Gear case, an air sealing system is provided. Hot primary air for drying and carrying pulverized coal, enters through insulated Mill side and Liner Assembly. Tramp Iron, pyrites and stones coming in the mill with raw coal move out of the bowl and being heavy, fall into the mill side and linear assembly.

The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a predetermined size in order to increase the surface area of the coal. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.
