Product Description 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. 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. ③ This high quality, precision-machined DY368 mill is easy to set up and use. Just using a 40w gear motor at 75 RPM gives you a crush rate of 22 pounds per min making the big grain bills fast and easy. ④ The DY368 grain mill is perfect for large batches and high efficiency milling. Using Guide: ① Clean it with water before using. ② No need to coat vegetable oil on the surface of rollers during production process.
