ABSTRACT:
An improved roller grinding mill in which a material grinding chamber is supplied with air in a tangential flow path through a multiple array of tangentially directed passages, material grinding rollers operate in a direction counter to the tangential air flow into the grinding chamber, and plows rotating in the same direction with the grinding rollers and formed with sloped surfaces for imparting an upward lift on the material to be ground for improving the fluidization of the material and maintaining a substantially constant particle size for delivery through the mill outlet.
