Introducing the newest player in the home brewer mill market. This is a fresh design meant to compete and win against the best milling products available. It consists of a 6061 aluminum block frame with two 6" long, 1.5" wide steel rollers riding on SAE 841 oil impregnated bronze bushings. Monster Mills use a superior grade of steel that is much harder than what is found on most comparable products and in most cases will last almost twice as long. The drive shaft, and all the axles are integral to the roller rather than screwed into the ends. This means that the mill works great driven clockwise or counter-clockwise. All the axles are 3/8", with minimal freeplay in the bushings.

One of the knurled steel rollers is driven by a standard 3/8" electric drill or hand crank (not included) to feed the grain through the adjustable gap and crush the grist. Both ends of the non-driven roller ride in bushings that are offset and mounted in an adjustable knob. The knob is held in a fixed position by a set-screw that you can loosen to adjust the mill. This system provides an adjustment range of .070". Our knobs are made from 303 stainless steel for excellent durability, and are larger in diameter than the competition, as well as knurled for a positive grip. We've also added a groove in our newest design knobs with a matching rounded head on the thumbscrew that allows for a much better grip on the knob to avoid gap changes while milling, and also providing knob retention.

Base and Hopper packages are available, and generally recommended unless you have your own plans for mounting this mill body.  Check out our Complete 2 Roller Monster Mill Packages.

If you don't purchase our base and hopper, you will need to fabricate one to feed the grist through the mill. The mill can be mounted above or below the base and attached using the mounting bolts included in the package.

I am very happy with my new Monster Mill 2 roller mill. I have put approximately 200 lbs of grain through it since recieving it. No jams, grinds consistently and quickly. Thank you Monster Mill.
