WESTERIA® WINDSIFTER AirStar®

The windsifters from Westeria® are designed to be rugged, powerful and energy efficient. A powerful method to separate heavy and light materials is what sets the patented Westeria® windsifter technology apart. In the windsifter, the materials are separated by a process that is divided into three main components: the acceleration belt, the air jet and the windsifter separation drum.

With its uniform and single-layer distribution of the input material, which is distributed homogeneously across the entire width of the windsifter and fed to the feeding belt, the windsifter achieves excellent separating results.
The material in the windsifter is accelerated to an adapted speed here and transported to the ejection edge. The materials falling from above get into an up current that is generated through an adjustable air jet that is attached in the windsifter underneath the feeding belt.

The air stream meets the upper area of the rotation drum in the windsifter and is fed through it into the expansion chamber with the laminar flow. The material in the windsifter meets the air flow and is separated into light and heavy materials.

The light materials are transported with an air flow with high speed into the expansion chamber, where the air speed is reduced so much that the light materials reach a container or a discharge belt. The heavy materials fall down from the rotation drum in the windsifter into a container or onto a discharge belt.

The air volume brought into the expansion chamber is removed again in the upper section of the windsifter and, depending on the individual application, is once more drawn in by the blower or routed into a filter system. To retain high-grade recycling raw materials, Westeria® has designed a special windsifter to unerringly sort the input material into three fractions with a high degree of selectivity.
