The disc mill is designed to size-reduce whole corn kernels. The disc mill consists of 12" diameter stator (stationary) disc and a 12" diameter rotor (revolving disc). The gap between the stator and rotor is adjustable. The gap width determines the size of the corn particles produced from the incoming whole corn kernels. Initially, the corn kernels are scooped into a feed hopper on top of the disc mill, which has a feed auger located at the bottom of the hopper. Whole corn kernels are feed directly into the mill’s grinding chamber by a feed auger. The feed auger speed is adjustable by means of a variable frequency drive. The feed speed is generally 400 RPM for corn grinding. The speed of the rotor in the mill is adjusted by a variable frequency drive (VFD). The rotor speed is generally 1200 RPM for corn grinding. The resulting ground fractions are collected together at the exit point located at the base of the mill. The disc mill is a wet grinding mill so water must be flowing down through the mill from the feed hopper by means of a cold-water hose during grinding.
