A continuous grinding system for comminuting material in a liquid includes a grinding vessel and a rotating shaft carrying one or more mixing arms disposed within the vessel. A funnel-shaped housing and a cylindrical extension project into the vessel and the rotating shaft extends through the housing and the extension with the mixing arms being disposed beneath the extension. The rotating shaft also carries one or more radially projecting, angled impeller blades which are disposed within the extension. The blades may engage the extension in which event the extension may be separate from the housing or may terminate short of the inner wall of the extension in which event the extension may be secured to the housing. The cylindrical extension in a modified form of the invention extends into the housing a distance equalling from about 10% to about 75% of the depth thereof and preferably from about 50% to about 55%.

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.
