Mill like a Pro with the MillMaster Mini Grain Mill from MashMaster - the only geared roller mill on the market. Brew when you want to brew with fresh cracked grains using hardened 420 Stainless Steel Fluted Rollers. Mill Master Geared 2 Roller Grain Mill feature cutting edge design with good old fashioned reliability so you can mill your heart out and brew like a pro with consistent crush with a fully adjustable precision mill.
130 mm (5"approx.) precision machined rollers
39 mm (1 1/2") diameter rollers
26 flutes per roller
420 Hardened Stainless Steel Rollers as Standard high corrosion and wear resistance
12.7 mm (1/2") drive shaft keyed for easy motorization, drill drive or hand crank
additional 3 flat triangular shank drive shaft designed to fit a 3/8 th drill chuck for improved torque and centering.
oil-impregnated sintered bronze bushings, carry a higher load, need less maintenance, and dampen vibration better than their rolling-bearing counterparts.
Strong aluminum frame
Built in gear guard
Asymmetrical saw-tooth fluted rollers provide a cutting on cutting crush as used in high end commercial mill rollers
Flutes are angled to provide additional strength, durability and wear resistance
Cutting on cutting action reduced excess flour production and reduces husk damage to improving lautering.
Made from heat treated 420 Stainless Steel for a long service life
Roller Gap Adjustment
Set gap marks for ease of adjustment and repeat-ability
0.0 mm to 1.9 mm infinitely adjustable gap setting for precision control and accuracy
304 stainless steel the eccentric adjuster
Quick Adjustment side locking pins
Gear Driven Rollers
Gear rollers make it possible to do away with course husk ripping and tearing knurls found on other mills.
Only geared roller mill on the market that is fully adjustable at both ends.
Synchronized rollers for consistent crush which is sensitive to RPMs and differential roller speeds
The geared rollers ensure an easy and smooth feed of malt into the grain mill from start to finish.
Mill Master grain mills reflect 10 years of design evolution, experience and learning. The gear driven, asymmetrical saw-toothed fluted rollers are the heart and soul of the mini mill. Some customers have removed the gears to test if it is a sales gimmick, all then have promptly reinstalled the gears after they noticed a decline in the crush quality. Mill Master have tested the mill without gears because if they were redundant we would have removed them and passed the savings onto our customers. The gears are not there for show, they improve the crush distribution and ensure grain feeds into the rollers every time.
Mill Master have used knurled rollers in the past which suffered from wear and less than Ideal ASBC grist distribution. After testing dozens of fluted rollers designs they arrived at a design based on commercial mills that use a cutting on cutting saw tooth pattern. This flute pattern reduced husk damage and reduced the flour proportion in the grist. Fluted rollers improves the stability of the grist distribution at different roller speeds. The fluted rollers deliver a more consistent grist distribution regardless the roller speed of between 120 to 530 RPM. The cutting edge of the flute is stronger than a knurled roller because it has more material behind it. Made from a durable heat treated 420 Stainless Steel. Because even flutes on commercial 6 roller mills eventually dull after many tons and years of operation, the unique design of the mill allows you to flip the mill upside down and the roller that was the back edge /dull roller becomes the new cutting edge roller and the dull cutting edge becomes a new back edge/dull roller. In effect increasing the service life of the mill.
We doubt the average home brewer will experience flute wear which would require flipping the mill, but a home brew shop milling tons of malt may experience this at some point in the future. Mill Master have used sealed roller bearings in the past, which allow you to freely spin the rollers with your fingers for longer, looks cool for sure, but when milling by hand or using a motor the difference in friction and resultant torque required to power the mill is negligible. There are no savings in motor size or muscle power that could justify the use of rollers bearings in a home brew mill. Mill Master no longer use sealed roller bearings because they simply do not withstand the high radial loads required for milling. It did take years, for power users such as home brew shops to experience roller bearing failure but it did happen. That is why Mill Master Mini Mills use bronze bushings and not roller bearings.
Mill design has evolved over time and Mill Master value past customers as much as they value potential new customers. Mill Master have maintained backwards compatibility whenever they can to ensure parts and serviceability in the future.
Drill or Motor Recommendations for your MashMaster Mini Grain Mill:
These two drills are the manufacturers recommendation they are both essentially the same drill to power your MashMaster Mini Grain Mill like a pro!
Three stage planetary gearbox, about 110Nm of torque (the D.C. 200-250w motor kits are only about 20Nm off memory). Under load with full trigger pull at its lowest setting it will operate the mill at about 220RPM and highest setting 530RPM according to the tachometer on my test bench.
If you are milling commercial volumes we recommend an explosion proof 4 poll motor and a helical or spur gearbox attached by a 1/2 flexible coupling.

Frequently Asked Questions:
Q: I have received my mill and hopper I ordered from you and it certainly looks the goods! The only thing that I haven't figured out, is what the pin, about the size of a match is for. Can you enlighten me?
A: The pin is actually a key, it fits the industry standard key-way on and mates with the key-seat on the 1/2” shaft.
Q: What type of Mill Motor do you recommend for the Mashmaster Mini Mill?
Ideal milling speed is between 220-530RPM, you will get a better crush (because of the cutting action of the rollers) at speeds above 110RPM (the hand crank speed which crush and cut less). Mashmaster recommend going with a biggest than necessary motor 750W or larger is their preference because they need to make recommendations based upon continuous use, intermittent use lets you run much smaller motor for shorter periods of time, you need about 40Nm of torque to drive the mill again more is better especially if you end up milling unmalted wheat to a fine powder you will need a strong motor, corn adjunct etc also require more power.
Ebay or a commercial supplier of industrial motors is where you could start for high end commercial motor applications. DC motors provide exceptional value for money as well and worth looking at for example motion dynamics used to use a 12V DC setup with converter as a key for home brewers.
MashMaster have designed the mill to be used with a geared drill drive, a cheap Ozito Mixer or Hammer Drill will work wonders (they come with a 3 stage planetary gearbox you would pay twice the price for as a stand alone product). This is what MashMaster used for all their Mill testing as they were changing rollers to test dozens of rollers designs.
MashMaster have tested the mill for a short run on a DC brushless (has greater torque) cordless Ozito Drill and that worked as well, which if you are milling outside, always a good idea to keep you flour dust away from your brewery makes life a little easier.
Q: Can I use my MashMaster Mini Mill to mill unmalted cereals and grains for Distilling?
A: MashMaster Mini Mill was designed for crushing malt for brewers and distillers but not unmalted cereals like Corn for example. If you are looking for a mill to crack and grind down Corn or unmalted barley to a fine grist size for distilling, we recommend you search for a hammer mill or flour mill designed for this specific purpose.
