Union Process' new attritor.
Union Process' new attritor.

The 250SD dry grinding attritor has CE certification and is powered by a specially engineered 150 HP motor which provides 425% starting torque. It features a mill that was designed specifically for metal-free grinding. The grinding tank is lined with ceramic tiles and the agitator arms are sleeved with tungsten carbide.

The attritor is designed to operate in continuous mode which allows for high product throughput. Material is fed into the attritor at the top, and is reduced in size as it passes through the agitated media bed. The finished ground product is discharged through multiple specially designed dry grind meter valves positioned at the bottom of the tank. A dry-grind aid metering pump is also included, and the final particle size of the material can be controlled by varying the feed and discharge rates.
