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.
Add the hopper extension to increase the 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.
The 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.
