New "QL" Circulation Attritor Grinds Faster
December, 2001
Akron, Ohio...The "QL" Attritor, a new, improved addition to the company's line of circulation Attritor mills, has been introduced by Union Process, Inc., inventors and developers of Attritor technology.
Like the company's original "Q" mills, the "QL" is a circulation grinding Attritor that includes a large holding tank that is typically about ten times the size of the Attritor. What differentiates the "QL" from other "Q" Attritors is the inclusion of specially configured arms that are designed to grind faster and create more agitation than conventional "Q" mills. The benefits result in a more elficient grind. This new
"QL" design can be adapted to the oriainal "Q" machine with some shaft changes and modifications. Customers who currently own a "Q" machine are encouraged to contact Union Process for details.
The key feature of the "Q" design is high circulation (or pumping) rate. In this unique design, the entire contents of the holding tank are passed through the Attritor about eight times an hour. This high pumping rate results in a faster grind and a narrower particle size distribution.
Grinding media for the "QL" range in size from 3/32" to 1/4" in diameter. Typical media include chrome steel, steatite and zirconium oxide.
