The SST 720 provides a really large and long screening drum – and thus plenty of screening area that is always optimally utilized thanks to the controlled material feed system. This in turn ensures ideal screening results.
SPECIALS
The drum of the SST 720 has a diameter of 2 m and a length of approx. 7 m, providing a screening surface of 38 m2 that is fully utilized thanks to the patented material infeed that is controlled in line with machine loading.
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. Power is effectively and mechanically transferred by the direct sprocket wheel drive with geared motors to the screening drum’s body. The enclosed design of the drum housing ensures that the emissions from the SST 720 are not released to the environment but are removed using extraction devices in a controlled manner.
The screening drums of the SST 720 are identical to those used in our mobile machines and are thus interchangeable. In this context, there are a wide range of screening drums available that ensure the right drum for every application and maximum flexibility, particularly for continuous operation requirements.
