The Beast Monster Mill MM2
Jun 25, 2014· I purchased a Monster Mill just over a year ago, model MM2 with two ″ x 6″ long rollers and the 1/2″ diameter shaft upgrade. Monster Brewing Hardware makes a variety of 2roller and 3roller models, with ″ and 2″ diameter rollers. The rollers are available in standard 1144 steel, or 303 stainless steel.
