Since even and precise crushing is also crucial for the best possible beer, the roller is the most important part of even crushing. The distance between the two rollers can be adjusted with screws, 0-2.5 mm can be adjusted and it can be applied to different particle sizes. This high quality precision machined DY368 grinder is easy to set up and use. If you only use a 60 W gear motor with 75 rpm, you can achieve a crush rate of 20 kg (44 pounds) per hour, which allows the large grain notes to be processed quickly and easily. We use real bearings for the roller instead of brass bushings. Real ball bearings not only extend the life of the mill, but also increase the efficiency of the whole grinding process.
