The only mill you will ever need!
After grinding 300 pounds of grain, I am very satisfied with this mill. At .050 gap, I hit 82% mash efficiency. I built my own hopper and stand. Powered by a Harbor Freight 1/2 drill, it works great. If it stops grinding, the non drive rollers are jamed. Just unplug the drive motor and spin the non-drive rollers by hand to clear them. This mill is strong and well designed!

good quality grain mill!
As other review- the mill is built very solid. Have been using one for over a year now and efficiency has increased to 79-82%. Complete control of the crush. My understanding is a model coming out with a base and hopper for the non-DIY'er. Really satisfied with quality and service of this mill.

mill kicks {tokhes}
i bought this mill knowing i would build a base out of an old oak microwave stand.i did purchase the hopper.i then used an old heavy duty geared down drill and hard wired it in with an on off switch and a high amp dimmer switch too control the speed of my crush.this took some time to set up but thats most of the fun anyways right?after using this set up a couple times it is awsome.i can crush my grains now without the help of someone holding the bucket (i used to borrow my buddys grain crusher).and it does the job great.i would definetly recommend this product!

Excellent mill for maximum efficiency
This is a really solidly built mill. Looks fantastic when you get it out of the box. Fully adjustable crush, so you always get the best out of your system. More for the DIY brewer then the someone looking for it to be ready to use as soon as you get it. Complete freedom to design your own base and hopper. Plus the ability to change/upgrade the design as your system grows. The thumbscrews on the side are great for holding a 1/8" window of plexiglass in place so you can monitor your crush and feed.

Expensive but efficient
This thing work great. It will stick once in a while. This from adjusting the bottom roller not correctly.

Monster Mill 3 ROCKS!
Worked the first time right out of the box! I've used it 3 times, and have not had ANY issues, great crush, very efficient. I have used a corded power drill with no problems, and now it's attached to a direct-drive motor with reduction gears turning at 240 rpm. Flip the switch, load up the hopper, and away it goes. Crushed 12 pounds of 2-row in under 3 minutes.

Hello I Bought the monster mill 3M 2 month ago and I wolud like to know how can adjust the first 2 rollers because the space is too smal and the milled grain its like dust. I need to get a kind of mill more gentle

BEST ANSWER: This is a three roller setup. The aadjustment in only in the third roller. I initially set mine up to what I thought was a course grind, but it resulted in a much to fine of a crush. I then set the rollers up to what seemed to me like the fine crush setting and got a good crush. At least for me the adjustment is counter intuitive. I then marked the position on the adjusment knob to index by.
We would like to buy a (Monster Mill MM3 3-Roller Mill). We see the drive shaft is a 3/8". Everywhere we have looked, Granger, Climax, etc. there are no step up adapters for any 3/8" drives. We can find 1/2" or 3/4' or bigger but nothing is made to clamp on to a 3/8" drive. If this is made for motorization, can you instruct us to how to step up a 3/8" drive or how to motorize it?

BEST ANSWER: The 3/8" integral drive shaft w/3 flats for drill driving, mean that this mill can be driven by a power drill with a 3/8" chuck. Monster Mill has recommendations on how to motorize their mills here: https://www.monsterbrewinghardware.com/store/pc/FAQs-d2.htm#q6
