HOW CIRCULATION GRINDING
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.
