The Alpine ATP Turboplex Air Classifier is ideal for ultra-fine classification of superfine powders. The patented multi-wheel design offers the same sharp top cut as a single wheel Alpine ATP, but can achieve up to 6 times the capacity of a single-wheel classifier. The classification of the product is a function of the peripheral speed or the speed of the classifying wheel and the radial speed of the air flowing through the classifying wheel. The material’s fineness can be controlled by altering the speed of the classifier wheel. Rejected material is discharged at the bottom of the classifier.

 The Alpine ATP Turboplex Air Classifier can produce fines in the range of D97=4 µm or finer. The mono-bloc classifier wheels are available in SiC or Alumina. In this wear-resistant construction, the unit can operate at the same speed as the steel classifier and thus achieve the same particle size cut. The mono-bloc design is ideal for processing abrasive materials such as feldspar and quartz.
