Union Process, Inc. produced and delivered a “Q” series circulation Attritor to a major coatings and colorants technologies supplier in the U.S.
The UP Q-25 Circulation Attritor is fitted with a 27.5-gallon grinding tank capacity, a 250-gallon circulation tank, a 25-gallon media volume, and a 20 HP explosion-proof motor with variable speed drive for precise speed control.
The unit also features an alumina-lined grinding chamber, ceramic agitator arms, and an advanced control system that simultaneously monitors and regulates temperatures, flow rates, batch times, and other process-critical functions.
“This model is widely recognized for its robust design and rugged build, in addition to its proven technology,” said Chuck Major, UP sales manager. “Because so many of these Q-25 units are in use, they’re also very easy to service, maintain, and upgrade.
“The key advantages of circulation grinding include a high circulating or pumping rate – the entire contents of the holding tank are passed through the mill up to eight times per hour, resulting in a faster grind and narrower particle size distribution,” Major added. “Unlike a continuous machine where the slurry makes a single pass, the material makes many passes through the grinding chamber until the precise desired particle size is obtained.”
