CASE STUDY: Granite Desegregator

The aggregate/cement industry suffers substantial maintenance expenditures due to aggregate wear, erosion and corrosion of the metal substrates on material chutes, sand screws, end loader/dump beds, augers and conveyors – anywhere materials are transported and/or change direction. In this particular situation, an aggregate chute was constantly being damaged by impact and abrasion. Several steel plates with 2" of mechanically attached rubber were fastened to the chute to protect it. This proved to be a short-term solution as these plates would only last about three weeks before requiring replacement. The abrasive movement of the granite wore through the rubber facing to the steel plate and into the steel chute.

The Rhino Linings® system provided excellent protection against aggressive abrasion and sealed the metal substrate, preventing the onset of corrosion. Rhino Linings had been protecting this chute for over 26 weeks with 11,000+ tons (9,977 t) of 3/4" to 1 1/2" (1.91 cm to 6.35 cm) aggregate running over it 5 days per week.
