SDi windshifter

The SDi is a semi-mobile, plug-and-play windshifter using industry-leading negative pressure technology to sort a wide range of material by density.

The SDi series is available in two models, semi-mobile and stationary, with an integrated dust filtration system, an electrical cabinet, support and for abrasive materials with a wear resistant (WR) configuration. Usable for virtually all kinds of solid waste up to 250 mm such as: Commercial and Industrial waste (C&I), Commercial & Demolition waste (C&D), Municipal Solid waste (MSW),  Refuse Derived Fuel (RDF), Automotive Shredder Residue (ASR), compost, and more.

Principle separating process

The picture below shows the operating principle of the SDi. The two-way fraction is created with an air separation point and a splitter drum, at which the heavy material is separated from the light material.
