Special Features

The screening drum of the SST 1525 has a diameter of 2.5 m, and with a length of approx. 2 x 7 m it provides a screening area of approx. 95.8 m². The patented material infeed that is controlled in line with machine loading ensures that this expansive screening area is optimally utilized.


To cater to the different areas of use, Doppstadt offers a variety of different mesh sizes to choose from for the screening drum. The machine may also be combined, e.g., with air separators or shredders from Doppstadt. This enables it to deliver consistently good results when screening compost, soils, light-weight building rubble, household waste, commercial waste, plastic, glass, paper, wood, biomass, sand, gravel, scrap or slag.


The screw is positioned internally, permitting a horizontal installation of the machine. The drive system or power transmission is realized using four drive units, which ensure a safe and quiet operation at all times in conjunction with the corresponding drum surface running on Vulkolan rollers.
