Union Process, Inc. has manufactured a C-60 Attritor for continuous processing of proppants used in the growing fracking industry. Proppants are typically comprised of treated sand or man-made ceramic materials that are designed to keep an induced hydraulic fracture open during or following a fracturing treatment. The continuous grinding C-60 tank is constructed from abrasion-resistant steel and has a gross volume of 79 gallons.
The tank lining is a special WellerCLAD composite overlay material that is also abrasion-resistant. The mill is driven by a 150HP motor and has a variable frequency controller that is installed in a NEMA enclosure. An LCD OIM (operator interface module) is programmed to display agitator RPM, motor amperage and motor HP being used.
