The Nihot DDS windshifter (Double Drum Separator) is the ideal solution for a three-way and high-volume separation. The DDS has two separating sections, this unique separating solution separates the input into three fractions:
heavy
mid-heavy
light
The DDS windshifter is especially capable of processing e.g.:
High moisture content
Abrasive materials (glass, inert, car scrap, etc.)
A high volume percentage of light materials (plastics and film)
Principle separating process
The picture below shows the operating principles of the DDS. The three-way fraction is created with dual air separation points and two splitter drums.
The DDS has many advantages, offering:
3-in-1 separation at high capacities
High operational reliability
Dust free operation – positive effect of negative pressure technology
Versatility to process a wide variety of waste streams
Adjustable separation settings during operation provide superior separation efficiency
Low energy consumption due to our unique configuration with a recirculation fan (less ductwork)
Low maintenance and very few wearable parts, i.e. reduced downtime, low operational costs
Equipped with stone catcher to prevent blockage inside the blow ducting
