Silver or Black Motor Send Random 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. 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. It is durable, easy-to-fabricate, clean, weld and finish.② We are using real bearing for the roller instead of brass bushings. Real ball bearings not only make the lifetime of the mill longer also make the whole grinding process more efficient.Using Guide:① Clean it with water before using.② No need to coat vegetable oil on the surface of rollers during production process.SpecificationsType: Electric grain grinderMaterials: Stainless steel roller, 6061 Aluminum for the mill body and hopperVoltage: 110V(US PLUG)Power: 60WSpeed: 75RPMRoller: 6"x1.5"diameter (15x3.8cm diamter)Output rate: 20kg/hour (0.3kg/min)Hopper capacity: 4LPacking size: 51*25*22cmG.W.: 9kgPackage Content1 X Malt Mill4 X Hoppers1 X Gear Motor2 X Rollers
