A high quality, precision-machined grain mill constructed of materials that will last a lifetime: 1018 cold-rolled steel for the rollers, 6061 aluminum for the mill body and hopper, tool steel for the axles with oil-impregnated bronze bushings.

The 5-inch rollers have a 12 TPI knurl to efficiently pull the grain through the rollers while leaving the hull intact to form an excellent filter bed for sparging. Rollers are adjustable at both ends to keep the gap spacing parallel and give a uniform crush along the entire length of the rollers. The default gap spacing is marked and set at 0.039" at assembly; the gap adjustment range is from 0.015" to 0.070".

The large hopper holds approximately 15 pounds of grain. No adapters needed to use a 3/8 drill motor; using a 3/8 drill motor at 500 RPM gives a throughput of 6 pounds a minute.

Comes with hopper, solid base, crank and handle, and lifetime warranty.
