Joined forces: disc screen & windshifter

Made by Bulk Handling Systems & Nihot

The SDS and SDi windshifters are generating a precise heavy / light separation for a large variety of waste streams. The DRS disc screen is the accurate sizing tool for a precise fraction size. With both in line you will have the perfect combination for an unbeatable performance.

More and more references of this combination are operational and can be found in China, Czech Republic, Costa Rica, Romania, Poland, Finland, etc.

DRS disc screen

The DRS (BHS Debris Roll Screen®) is the premiere sizing tool for Single Stream, Municipal Solid Waste (MSW), Construction and Demolition (C&D) waste, wood waste, compost, green waste, plastics, glass, tires and various other materials.

BHS Tri-Disc™ Technology

The unique BHS Tri-Discs™ are in-line from shaft-to-shaft, creating a precise opening for highly-accurate material sizing. Their hardened steel, triangular shape provides superior material agitation and true sizing in a small footprint.

Key objectives

  • Due to the special in-line configuration, shape (Tri-Disc™) and specific timing of the discs, long and flexible items are unlikely to wrap.
  • The special designed Tri-Discs generates a very effective ‘wave-like agitation’ to liberate the material while transporting over the screen deck.
  • Strong, completely solid and hardened discs.
  • First 1-3 shafts are used as impact shafts.
  • Inclined and declined decks available, depending on the nature of the waste.
  • Available in single, double and triple deck variations.
  • Double and triple decks impart a ‘waterfall’ effect, flipping material to ensure complete separation

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.
