Dry Ball Mill Classifying Plant

1.International standards and also most popular dry processing technology in mineral powder industry.
2.The handling of ball mill classifying systems is much more easy than with vertical roller mill systems, etc.
3.Variation of finenesses with ball mill classifying systems is more wide, from 300 mesh up to 3,000 mesh is possible, depending on the selection of classifier size.
4.Maintenance and costs for wear parts are very low with ball mill solutions.
5.Life-time of the system is much longer with ball mill solutions.
    Working Principle:Classifier, together with cyclone separator, dedusting filter and radial fan, forms a system of classification. Under the lashing force of radial fan, feed materials are brought with uprising air stream into classifying cavity from feed inlet of classifier. Under strong centrifugal forces of high-speed rotating turbo wheels, coarse and fine materials are separated. Coarse materials, together with some fine materials, lose speed after bumping against wall and fall to secondary draught. During strong washing of the secondary drought, coarse and fine materials are separated once again. Fine materials go up to classifying cavity to be classified continuously, while coarse materials fall down to discharging outlet and let out.
