Air classifier STRATOPLEX ASP II

The Stratoplex ASP air classifier has long been a guarantee for high performance in the fine to medium-fine separation range. In close cooperation with our customers, we have improved the classic once again. The result: an optimised machine concept with reduced wear and lower energy requirements. • Air classifier for high throughputs in the fine to medium-fine separation range of d97 = 10 to 150 µm • High fines yield at high precision of cut and high loading • Wear protection through ceramic coating on both sides • Low energy demand Principle of operation Because the drive of the Stratoplex air classifier is fitted underneath the classifying zone and the feed product is fed centrally from above, the result is an optimum distribution and dispersion of the product. The feed product is charged by means of the feed unit via the product intake to the centrifugal plate of the classifying wheel, where it is distributed uniformly and then catapulted radially towards the baffle ring. The feed material is deflected by the baffle ring and routed downwards into the classifying zone. The classifying air enters the spiral housing and flows through the helical vanes of the vane ring and the classifying wheel in centripetal direction. The fines portion is removed thereby from the feed material as it gravitates downwards in the classifying zone, i.e. the zone between the vane ring and the classifying wheel. The fines, extracted as a function of the cut point set on the classifier, are entrained in the classifying air and flow towards the fines discharge. The fines must be separated from the classifying air in a downstream collection device (cyclone, filter).
