ROTASCREEN® Trommels serve a limited range of applications that vibrating or oscillating screens can’t handle. They may be used in resource recovery to segregate solid waste in various forms including MSW (garbage), compost, incinerator ash and construction debris, or in mining and aggregate operations for scrubbing rock and sand.  Cost per ton-hour of capacity is high, compared with conventional screening machines.  Screening drum diameters range from 4’ to 10’, and lengths from 6’ to 70’.  Distinguished from low-end standardized designs, each ROTASCREEN is customized to its application, choosing from a variety of options in construction and power transmission.
