After too long, and a bunch of work, Monster Brewing Hardware now has a base and hopper to go with their mills. Finally, you can purchase our mill, and hopper/base system, and in a matter of minutes after taking it out of the box, be able to mill grain. No more fabrication required! Our goal was to make something that would ship flat using standard USPS flat rate packaging and hold as much grain as possible. This design allows us to minimize the necessary packing materials, and save you $$ on shipping costs, especially for our many overseas customers.
The hopper is constructed from 20 gauge G90 hot dip galvanized steel that should never rust. The material is more than 35 thousandths thick, and is super strong! The pieces are laser cut, and then CNC bent by our supplier in the USA. The hopper stands 9” tall above the mill, and the opening at the top is 11.5” by 12.75” with a capacity of at least 11 pounds of 2-row or pilsner malt. The hopper design directs the grist down into the mill gap, keeping it both away from the ends of the rollers, and from bouncing out of the gap. In testing there were no problems with positive feeding. The main six hopper parts are the same for any of our mills, while the sides that hold the hopper are different for each mill, and double as covers to keep the grist below the base.
At NHC 2010 several of you complained that our hopper just didn't hold enough grist for your tastes. Well, we at Monster Brewing Hardware always like a challenge, so our head hopper designer came up with an extension to please all of you. Total capacity is up to 39lbs, perfect for all 10 gallon batch sizes, and a single hopper fill. Made of the same durable materials, and bolts directly onto all of our existing hoppers with a perfect fit. Sold as an add-on to your new or existing hopper.
Because the parts are built very accurately, the holes line up perfectly. The whole works assembles easily in minutes with the included #8 machine screws, washers, and nylon insert lock nuts. We include nylon insert nuts so they won’t vibrate loose while milling. The hopper mounts to the top of the mill using the included ¼-20 half inch long mounting bolts. If you had an erector set when you were a kid, the process should bring back fond memories. (hopefully!) The only tools necessary for assembly are a Philips screwdriver PLUS an 11/32” box end wrench, socket, or a pair of pliers.
Our base is hand fabricated by a local cabinet maker from medium density fiber board, and measures just under 12” x 12”. The top edges and corners are radiused for smoothness, and the window for the grist to fall through is hand routed. The base fits over standard 5-6 gallon plastic buckets, and holds the mill frames straight and securely.
If you are ordering a hopper for an existing MM3-Pro, please note that the older models have taller frames (5") than the current frames (4.5"). I had a very small number of hopper sides made for the older tall frame MM3-Pro mills. Please let me know which frame size you need when ordering a hopper for an existing MM3-Pro mill.
