ABSTRACT:
A grinder includes a generally vertical, rotatable shaft having at least one set of cutter blades driven thereby and a fan assembly mounted on the shaft below the cutter blades in position to receive output therefrom. The fan assembly includes a fan disc secured to the shaft and rotatable therewith. A plurality of fan blades are secured to the fan disc in a generally radial orientation. Each fan blade includes a bottom flange secured to a top surface of the fan disc, a web extending upwardly from the bottom flange and a top flange extending outwardly from the web in a direction of rotation of the fan disc. The fan blades are preferably moveably mounted to the fan disc such that the angle of the fan blades relative to a true radial orientation can be adjusted.
