Perfect Balance of Power and Performance

The workhorse of the SM series trommels, the SM 720 provides the perfect balance of power and performance across a broad array of material applications. For operations that require high-volume screening, but not on a sustained daily basis, the SM 720 is designed to meet those peaks in demand without the need for a larger trommel. No other trommel in the industry offers the same efficiency and throughput. The new SM 720SA comes with a larger hopper and longer conveyors, increasing the throughput and stockpile capacity.
