Air Classifier ACL

Overview
The Bauermeister Air Classifier is used for the classifying of dry powders into two fractions, one above and the other below a determined cut size with a high degree of accuracy. The Bauermeister ACLs are designed to operate in a classifying system complete with its own feeding and product collection system, or alternately in combination with any conventional air swept milling system.

Feed material is conveyed with the main supply of air to the spiral housing. Due to the shape of the housing and the rotation of the separating rotor, a spiral current is created, in which the material to be classified is separated into two fractions, fine and coarse material. The fine material is sucked inwards through the rotor and leaves the classifier along with the air. The coarse material is hurled by centrifugal force against the housing wall and falls downward. Air also enters the classifier through a secondary inlet to classify the coarse material again, providing a better yield during the classification. Product is then discharged through a rotary air lock.

Key Features
• Cut size can be set within the range of 3 to 150 µm by variation of rotor speed as well as primary and secondary air volume.
• Available in different sizes for throughputs from 50 lbs/h to 20 t/h.
• Mild steel, stainless steel
• Easy access for cleaning and maintenance through inspection doors.
