Versatile Controlled air is a perfect medium in waste separation processes. It is versatile, offers higher flexibility then mechanical separation technologies and it guarantees a high separation efficiency. By using air, materials can be separated based on differences in specific density and shape.

Flexibility The Nihot Windshifters are characterized by their great flexibility: • Different (mechanical) settings are installed for exact and precise controlling of the air flow and thus the separation efficiency • Instead of a Combi Separator, a Rotary Air Separator can be installed when smaller capacities of light weight fractions are applicable • Flexible footprint; the Combi Separator or Rotary Air Separator can be placed anywhere within the installation Combination The Windshifter is a combination of a recirculation fan, a separation unit (the actual Windshifter) and a Combi Separator...

WS-S: Diagonal Windshifter The typical characteristic of a diagonal Windshifter (WS-S) 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. Process WS-S The input material is transported by conveyor (1) to the Windshifter separation unit (2) where the heavy materials are separated from the lighter materials. The heavy materials fall down (3) against the air flow. The lighter...

WS-V: Vertical Windshifter Is an ideal solution for removing light fractions from liberated and densified input materials. The WS-V is normally used in combination with a Rotary Air Separator for smaller fraction sizes and capacities. Process WS-V The input material is transported by conveyor (1) to the Windshifter separation unit (2) where the heavy materials are separated from the lighter materials. The heavy materials fall down (3) against the air flow. The lighter materials are aspirated by controlled air through a material duct (4) into a Rotary Air Separator (5). In the RAS the air...

WS-Z: Zig Zag Windshifter When the density of the heavy and the light fraction is very close and the fraction size is not exceeding 50 mm, a Zig Zag Windshifter proves to be a good solution. Process WS-Z The input material is transported by vibrating feeder (1a) or conveyor (1b) to the Windshifter separation unit with adjustable cascades (2) where the heavy materials are separated from the lighter materials. The heavy materials fall down (3) against the air flow. The lighter materials are aspirated by controlled air through a material duct (4) into a Cyclone (5) to separate the air from the...

Drum Separators Innovation Due to the changed composition of waste over the years, the percentage of light weight material in waste streams has increased substantially. To be able to process the high volumes of lightweight materials, Nihot has developed an innovative air separation technology to separate waste streams into two or three fractions; Drum Separators. The Nihot Drum Separators are designed to process up to 35 t/h of light weight fraction with a single unit. The handled input can easily go up to 50 t/h or more, depending on the nature of the input waste.

Flexibility The Nihot Drum Separators are characterized by their great flexibility. • Various (mechanical) settings are installed for exact and precise controlling of the air flow and thus the separation efficiency • The Light Weight discharge Conveyor can be adapted in different lengths and angles. Ideal when a certain height needs to be reached • The Light Weight discharge Conveyor can be adapted in different widths. Ideal for direct feeding of an optical sorter or evenly dosing a secondary shredder Combination The Drum Separator is a combination of a recirculation fan, a separation unit...

SDS: Single Drum Separator Single Drum Separators separate waste into two fractions; heavy and light. Process SDS The input material is transported by a frequency controlled input conveyor (1) into the Drum separation unit (2). Here the separation takes place. The heavy materials will fall down (3) before the rotating splitter drum and against the air flow. The light materials are aspirated and conveyed over splitter drum into the expansion chamber (4). Inside the expansion chamber the air expands by which the light materials drop onto the Light Weight Conveyor belt (5) and are discharged...
