Union Process Builds Four QL-100 Attritors for Specialty Ink Manufacturer

Akron, Ohio. . . Union Process, Inc., a manufacturer of grinding and dispersing equipment for a broad range of industrial applications, recently shipped four QL-100 Circulation Attritors to a large specialty ink manufacturer.

These high-production grinding mills are distinguished by their capability to take high pumping rates that result in a faster grind and a narrower particle size distribution. The Attritor circulation system typically includes a separate holding or premix tank (not shown) that can be ten times larger than the size of the mill. The entire contents of the holding tank will pass through the grinding chamber at least once every 7-1/2 minutes or approximately eight times an hour. Attritor circulation milling improves efficiency by passing material through the mill multiple times. The QL design includes specially configured agitator arms that are designed to increase production.

Each mill has a gross tank volume of approximately 122 gallons powered by a 150-HP inverter duty, explosion-proof motor. The mills were also mounted on 44-1/2" custom designed frame risers per the customer's specific requirement.

Other features of the circulation processing mode include:

  • Large-scale production capability
  • Easy and safe operation
  • Low maintenance and power consumption
  • Excellent temperature control
  • Ability to continuously monitor slurry throughout the grinding process
  • Requires smaller investment in grinding media
