For many businesses, an S&B blow-suction classifier is the first step into airstream sorting, and basically provides the appropriate solution when it comes to cost-effective system construction. Our expertise and continuous development have efforts enabled us to design an air classifier which, nevertheless, impresses with its efficiency and flexible scope of application.
Operating principle
The material to be classified is carried to the classifier head by a belt conveyor running with a variable belt speed. A well-aimed air stream is created by a blow nozzle under the end of the belt blowing against the material as it falls down, thus spreading the discharge parabola of the material to be sorted.
The heavy fraction falls down onto a discharge belt, while light material is either sucked up directly or blown onto the baffle plate located opposite. This contributes to an optimized separation of fractions as heavy material still carried along by the air flow will slide down on the plate.
