Union Process Builds Large Circulation Attritor System

Akron, Ohio – Union Process, known globally as a manufacturer of particle size reduction and dispersing equipment, as well as a supplier of grinding media and materials characterization services for a broad range of research and industrial applications, has built a QL100 circulation Attritor for a large automotive accessories supplier.

Chuck Major, sales manager with the company, noted, “A number of things made this project a “win-win”. Not only did the Attritor need to be explosion-proof, but the customer had limited space. So, instead of purchasing several large batch Attritors, we recommended a large 1,000-gallon pre-mix holding tank as part of the system to increase their total production capacity with only one circulation “Q” system Attritor. This same customer previously purchased a large S400 batch Attritor and this time needed a much larger capacity that we could accommodate with the QL100.”

“Therefore, the customer was able to produce 1,000-gallon batches, rather than 300-gallon batches, in less charging and discharging time and was additionally able to do this with the Q-100 Attritor that only required 4,000 lbs. of ¼” through-hardened carbon steel media, rather than 12,000 lbs. of ¼” through-hardened carbon steel media.”

This Q-100 Attritor has a grinding tank with a gross volume of approximately 111 gallons. The mill is powered by a 125 HP, 2-speed explosion-proof motor with a variable speed drive. An IEC starter and pushbuttons with a digital AMP display and emergency stop are mounted in a NEMA 7/9 enclosure and completely wired to the motor.
