Product Description This listing for DY368 grain mill is motorized with a drill. You don't need any additional attachments, just stick the drill on and go. It features an alloy block frame that houses two rollers on stainless steel real ball bearing instead of oil-impregnated bronze bushings. The drive shaft and all axles are integral to the roller, which makes it possible to drive the mill clockwise or counter-clockwise. 12 TPI knurl to efficiently pull grain through rollers while leaving hull intact to form an excellent filter bed for sparging ① As a consistent, precise crush is also vital for making the best beer possible, the roller is the most important part in the consistent crush. The DY368 roller is using food grade stainless steel, which has molybdenum added to its alloy content during production. Molybdenum provides an very high degree of corrosion resistance. This is an advantage for objects that require resistance to extreme environmental conditions such as salt water, de-icing salts, brine solutions, or other chemical forms of chemical exposure. Stainless steel excels in resistance to acids, bromides, and iodides at high temperature. It is durable, easy-to-fabricate, clean, weld and finish.Using Guide: ① Clean it with water before using. ② No need to coat vegetable oil on the surface of rollers during production process.Specifications Type: Electric grain grinder Materials: Stainless steel roller, 6061 Aluminum for the mill body and hopper Voltage: 110V(US PLUG) Power: 40W Speed: 75RPM Roller: 6"x1.5"diameter (15x3.8cm diamter) Output rate: 13-22lbs/min (6-10kg/min) Hopper capacity: 5kg Packing size: 51*25*22cm G.W.: 9kgPackage Content 1 X Malt Mill 4 X Hoppers 1 X Gear Motor 2 X Rollers
