OPERATING PRINCIPLES AND EFFICIENCY – Van Tongeren

The coarse product is scrubbed by the secondary air as it slides off into the coarse discharge outlet. Secondary air flow dislodges any fines adhering to coarser particles. They join the stray fine particles entrained by the eddy current and are returned to the classifier inlet point (9) and reintroduced into the classifying zone (10).
