Abstract
A continuous dry grinder for grinding particulate material with the assistance of grinding elements includes a comminuting vessel which contains the grinding elements and receives material to be ground through an upper feed chute and discharges the ground material through a radially mounted screen, valve and discharge chute. A motor driven agitator assembly is disposed within the vessel and includes alternating radially projected agitating arms and diverter discs mounted on a rotating agitator shaft. The agitating arms are L-shaped and have their short legs alternately projecting toward the top and bottom of the vessel.
