PRINCIPLE :
3/4 Roller Mill workson the pressure & Friction Grinding System. The Grinding is done between the stationary bull ring
and the rotating roller which sawing out wards due to thecentrifugal force.
CONTROL AND OPERATION :
The Mill base is made from cast iron. Theair chamber, Blower, Dust Collector, and dust lines is made from the mild steel.
The Gear box of Cast iron and have one set of hardened bevel gear. The vertical shaft has plough support, Mn. Plough and spider with the rollers which is hinged on spider. The thrust bearing is provided in the bottom of vertical shaft to hold the load of shaft assembly. The feeder is provided to feed the material in grinding chamber as and when required.
The grounded material is swept by air and carried to classifier. The wizzer classifier passes the material of required mesh and oversized particals are returned to the grinding chamber. Finally material is collected by cyclone.
