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 S-400 batch, wet-grinding Attritor for a customer in the roofing industry.

The S-400 represents the largest batch Attritor ever built by the 66-year-old company. Batch Attritors have the advantage of grinding material up to ten times faster than traditional ball mills. They are simple to operate, energy efficient and do not require premixing.

The largest ever batch Attritor has a new frame design utilizing a pivoting drive cantilever which allows for easy removal of the agitator shaft for maintenance and cleaning. The Attritor features a 400 HP TEFC inverter duty motor with a heavy-duty variable frequency drive controller.

The large tank accommodates 12,000 lbs. of through-hardened carbon steel grinding media.

Sales Manager Emery Li commented, "As indicated by this request for the largest ever batch Attritor, our grinding system seems to be an emerging opportunity for the building materials and construction industries. They are finding that Attritors, no matter how large, are reliable workhorses that can handle the needs of virtually any requirement."

Union Process is the inventor and developer of Attritor technology and manufactures wet and dry grinding mills as well as horizontal bead mills.
