Nihot supplies Dutch Waste Management giants VAR with combination air separation system for the cleaning of a compost "ent-fraction"

With more than 60 years experience, Nihot is a proven market leader in the supply of air technologies for the separation and upgrading of miscellaneous waste fractions.

In waste processing, controlled air is a perfect separation medium, both in terms of process technology and business solutions. By using air, materials can be separated based on both material density and shape. Air technology is versatile, offers greater flexibility than mechanical separation technologies and it guarantees high separation efficiency.

At waste management company VAR, close to Apeldoorn in the Netherlands, Nihot Recycling Technology B.V. installed in November 2008 a combination of a Single Drum Separator (SDS) and a Windshifter (WS) (mounted at the head pulley of the discharge conveyor of the drum separator) for the cleaning of a compost "ent-fraction".  Both machines were integrated in an existing configuration where little space was available.

The Single Drum Separator processes approximately 20 tons per hour of compost where heavy particles/objects, such as rubble, glass and metal parts are separated from the compost fraction. The Single Drum Separator has an effective belt width of 1m. (Type SDS-1000) and processes a fraction size of 50-250 mm. The Single Drum Separator is fed by an existing star screen where the 0-50 mm compost fraction is being removed.

The heavy fraction, being approximately 1 ton per hour, drops before the splitter drum. The compost fraction is transported over the drum into the Expansion Chamber, after which a Windshifter, mounted at the head of the discharge conveyor of the Single Drum Separator, separates the light fraction such as plastic film, paper, plastic parts, from the compost fraction. This light fraction is taken to an existing cyclone where the material is being separated from the air. With both the SDS and Windshifter operating at full capacity in January 2009, VAR are delighted with the efficiency and end product from the combined system.
