WSS windshifter

The Nihot WSS windshifter is the ideal solution for any operation, but especially in tight spaces and in retrofits. Material is pneumatically conveyed, creating a great deal of flexibility for conveyor placement and duct routing.

The typical characteristic of a diagonal windshifter (WSS) is the use of a blow nozzle. About 60% of the aspirated air is returned back into the system. This allows for a smaller dust filter. But more over it helps to control the separation efficiency since we can fully adjust the blown air separately from the aspirated air. The WSS windshifter offers high separation efficiency with flexible footprint and can process fraction sizes of 20-400 mm and is mainly used in light packaging waste (DSD/PMD), PET, MSW and compost.

Principle separating process

The windshifter is a combination of a recirculation fan, a separation unit (the actual windshifter), and either a Rotary Air Separator (RAS) or Combi Separator. This configuration is individually designed and ideal for any operation, especially in tight spaces and in retrofits. A RAS can be installed for light weight fractions up to 3 t/h. When more capacities of light weight materials are applicable the Combi Separator can be used instead.

The picture below shows the operating principle of the WSS. The separation unit of the WSS windshifter has a diagonal design. In the diagonal shifter unit, the heavy materials are separated from the light materials.

DDS windshifter producing high quality SRF

The customer, N+P Subcoal®, is more than pleased with the performance of the windshifter. The line is processing pre-separated C&I/MSW waste and the DDS windshifter adds value by protecting the secondary shredder, removing inert and creating high calorific value SRF (used in a kiln or boiler).

One DDS windshifter = three fractions

1 windshifter = 3 fractions The DDS windshifter is specifically designed to separate a waste stream into three fractions (heavy, mid-heavy and light) all done in one pass. It was originally designed for C&D and C&I recovery applications by separating the input into: stones, wood and RDF material.
