When selecting a milling system, a material's particle size requirement is often the first and best criteria to hone in on a particular method of size reduction. A vast majority of applications call for reduction of material particle size from 6 inches to sub-micron. Prater's equipment selector can help manufacturers match an appropriate ...
Material to air flow ratio can have dramatic effects on classifier efficiency. 4. Excessive wear. Check the internal areas of the classifier for wear. If you discover any holes, then your material could start to migrate between the fines and coarse side of the classifier by sheer gravity.
Classification in an air classifier is the result of opposing forces in the system. Typically, the classifier comprises a rotating disk that imparts an outward centrifugal force on the particle. Opposing that force is the inwardly moving air flow that provides an inward force on the particle. Both the outward centrifugal force and the …
Hosokawa Alpine classifiers and air classifiers make everything fine! No matter what fineness you require, our classifiers were developed for a wide range of applications. As a result, they cover a wide fineness range: from d 97 = 2 µm to d 97 = 200 µm. See the individual machine pages for details of the fineness ranges.
