Union Process Introduces a Lab Model Attritor for Small Media Milling

Akron, Ohio. . .Union Process, Inc., known globally as a manufacturer of particle size reduction and dispersing equipment as well as related services for a broad range of research and industrial applications, has built an 05-SDM hybrid mill capable of small media milling.

The model 05-SDM combines the features of a standard wet grinding, laboratory Attritor batch mill with the added benefits of being able to handle small media milling. The typical Attritor benefits include simple operation, energy efficiency, rugged construction, no expensive shaft seals to maintain, and the ability to inspect and add material at any time during the grinding cycle. By adding a specially designed shaft and proprietary Delta Discs, the mill is able to use mini media from 0.25mm to 3mm and operate at the high shaft speeds (from 300 to 3000 RPM) required to energize small media.

This particular mill was shipped to a European customer and included an electronic variable speed drive (VFD), 3 HP motor and was CE Certified. The operator interface module was programmed to display agitator RPM, motor AMPS, and motor HP being used.

This mill was of stainless construction but metal-free models are also available. The mill processes about 1 to 1-1/2 liters of slurry and has a side discharge with a media retaining screen.

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