Product Description
\t
Independent research and development,based on German technology

AF Air classifier


Description
The feed material enters the classifier with the main air flow which can be a highly cost-effective process option if integrated into a system with direct pneumatic feed. The classifying wheel speed can be steplessly adjusted by means of a frequency converter.By altering the classifying wheel speed,the particle size can be easily adjusted even during operation.Fine particles whose size is below the set cut point are transported through the rotor blades along with the classifying air,are then discharged via the fines discharge in the main air flow,and finally collected in a suitable filter.Coarse particles are rejected by the classifying wheel and are discharged via the coarse material discharge.Before being discharged,the coarse material is rinsed intensively in a spiral flow taken from the secondary air stream to remove any last fine powder,this step improves the precision of cut and increases the fine powder yield.

The dry classification is achieved based on the size,shape and density of particle,the classifier can be used with every kind of grinder in a closed negative operation,the integration of size reduction and classification reduce the production cost,and the flammable and explosive,oxidizable materials can be classified with inert gas shielding.

Feature
1.Optimized impeller structure design of vertical single rotor and horizontal multi-rotor,which can be composed closed circuit system connected with ball mill,using multi-wheel technology to improve product fineness and increase capacity.
2.Classification efficiency can be 60-90%, d97=2.0 ~150um is adjustable.
3.Designed to the infinitely variable speeds and wear resistant,easy clean and change varieties of product.
4.Negative operation is free from dust,low noise and vibration.
5.Eliminate the oversize and superfine particle existing in product,free of particle entrainment.
6.In conjuction with several classifiers,get different particle sizes.

Application
Mineral:calcium carbonate,kaolin,quartz,talc,mica,zircon sand,feldspar.
Chemical,metallurgy,abrasive,ceramic,medicine,pesticide,food,health products,new material,refractory material,etc.
