Making money making topsoil is almost entirely dependent on the screen you use to produce it. Ecoverse offers extremely efficient and highly productive Doppstadt SM series trommel screens, available in a range of sizes and throughput to match any soil screening volume. Durable steel punch-plate drums and quick change sizing screens make Doppstadt trommels the perfect screener for topsoil production. In wetter environments or for high-moisture content soils, Backers star screens offer high-production screening. In two or three-deck configurations, large rocks, smaller aggregate and fine topsoil fractions can all be created in a single pass. Add a pre-screener scalping deck to remove even larger contaminants before entering the screens.
