Union Process Introduces Production Mill for Small Media Milling

Akron, Ohio. . .Union Process, Inc., known globally as a manufacturer of size reduction and dispersing equipment for research and industrial applications, has produced a new production-sized small media mill for the ink, coatings, and paint markets.

The DMQ-10 combines the best features of a traditional horizontal small media mill with the added benefits of circulation grinding. The result is a versatile mill capable of providing a cost-effective, size reduction solution for grinding large quantities of material. Although the DMQ Series is able to operate in either circulation or continuous mode, using the mill for circulation grinding offers some unique benefits including a narrower particle size distribution, the ability to continuously monitor the slurry, and the ability to sample or add ingredients to the premix tank at any time. Also, temperature can be controlled more precisely since the slurry spends only a short period of time in the grinding chamber.

The circulation grinding process involves the use of a large process/holding tank in addition to the DMQ Mill. This tank is typically 10-20 times the volume of the mill's grinding chamber. The material is pumped through the mill at a high rate of speed and circulates through the holding tank. Complete turnover of material takes place every 5-10 minutes.

The mill features a large, heavy-duty media separator located at the end of the mill for easy servicing. A rail system makes maintenance and/or tank removal easy. Indexed discs provide uniform media distribution. Adjustable product discharge openings in the screen maximize versatility and throughput by accommodating grinding media from 2mm to as small as .3mm.

Union Process is the inventor and developer of Attritor technology and manufactures wet and dry grinding mills as well as small media mills.
