ABSTRACT:
A disc mill assembly for a pulverizing system includes: a flywheel, a water jacket, two disc blades, and two ring clamps. In alternate embodiments, the disc mill assembly also includes: an air inlet to provide input air from an external air supply and an improved blade height adjustment mechanism. A disc blade is also provided. The disc blade is a single member with a central aperture that is the only through hole in the blade. Users may cost-effectively adopt a disposal versus sharpening policy for replacement of the disc blade. A method for controlling a temperature of material in a disc mill assembly having first and second disc blades is provided. The method includes: directing an adjustable input air stream, directing material to be ground, monitoring the temperature of the material, and controlling the air stream directing and/or the material directing in response to the temperature monitoring.
