HOW CIRCULATION GRINDING WORKS The circulation grinding method involves a grinding mill (in this case, the DMQX™ Bead Mill) and a large process/ holding tank that is typically about 10-20 times the size of the mill’s grinding chamber. This proportionally-sized tank allows the turnover in the holding tank to happen about every 5-10 minutes. To assure optimum grinding and a narrow particle size distribution, the material must be pumped through the chamber at a very high rate. The DMQX™ has a special media separator with a large, open discharge area to help facilitate this high flow rate. High pumping rate allows material to completely turn over in the holding tank every 5-10 minutes. A HYBRID OF BEAD MILLING AND CIRCULATION GRINDING As the company that first introduced Circulation Grinding to the world in the early 1970s, it makes sense that Union Process is also the company to combine the benefits of Circulation Grinding with the advantages of Bead Milling. The DMQX™ Horizontal Bead Milling System was designed to do just that. Model DMQX-10 ™ On the cover: DMQX-80
