NOLL‘s SeparaNo®-E classifier series – specially designed for the classification of non-abrasive and non-sticky materials – represents a new, revolutionary classifying technology. We have reversed the classifier‘s direction of flow and provide a new, improved product input. We have also optimized housing geometry: the classifier‘s arrangement is now eccentric, permitting a considerable reduction of the additional air required, while minimizing abrasion. Neither coarse particles nor grinding elements get in the way of classifying performance.
WORRKING PRINCIPLE CLASSIFICATION
The product enters via the primary air stream and is directly transported to our specially designed NOLL classifying wheel. Dry, oil-free air ensures uncontaminated feed material. Using centrifugal forces, the classifier wheel separates the fine particles from the coarse, allowing very steep particle size distributions.
The coarse material flows back down into the coarse material separation zone, where its particles mix with turbulent air, thus further separating small dust particles and eliminating agglomerates. The treated coarse particles continue through the bottom timing flap exit to be discharged and packaged.
The classifying performance is controlled and optimized by adjusting air volume and throughput, as well as by the classifying wheel‘s rotational speed. A specially generated air stream along the classifier wheel insures that no powder can enter the bearings or block the classifying wheel. The fine material according to specification exits the machine through its tangential exit, where it is packaged into the appropriate packaging
medium.
