The SM 514 trommel screen is the most powerful entry level trommel in the industry. With a throughput that can outpace much larger (and more fuel hungry) competitive machines, the overall performance of the SM 514 is unprecedented. Loaded with all the same innovative features as the entire SM series trommel line from Doppstadt, the SM 514 saves time, money and space without sacrificing output.
For lower-volume operations that still need to accommodate higher volumes on occasion, the SM 617 provides a step up in performance without having to invest in a significantly larger trommel. Available in both wheeled and tracked configurations (as are all SM series models), the extra horsepower and screen size of the SM 617 is there when you need it without sacrificing efficiency and footprint. Screen more in less space with the SM 617.
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, 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.
The largest trommel in the SM series collection, the SM 726 delivers the most efficient, high-volume output of any trommel screen on the market. This is the perfect machine for operations that screen in excess of 1,000 yards of materials daily, as it can be effectively employed across a very wide range of applications and materials. Available in wheeled and tracked chassis configurations, the flexibility of the SM 726 trommel screen makes it a top performer for both organic and inorganic material sizing.
The Doppstadt electric trommel screens are built to screen the most difficult of materials. Its helical-guide drum is a well-proven drum design with replaceable screening drums that can easily adjust to different screening tasks. The efficient mechanic power transmission is carried out by four direct wheel drives with compact geared AC motors.
