Hosokawa Alpine offers a wide range of classifiers, for a wide variety of different products and fineness  
ranges, tailored to meet the technical and commercial requirements of the individual application.

Gravity classifiers
Gravity classifiers are used for sharp separations in the range of 0.3-10mm. Classification takes place in  
every kink of the zig-zag tube allowing an extremely high and steplessly adjustable precision of the cut  
resulting in clean fines.

Wheel classifiers
Single or multi wheel classifiers are used for ultrafine separations. Coarse particles are rejected by the  
classifying wheel and discharged.

Hosokawa Alpine innovated the concept of multi wheel classifiers for increasing the capacity of the  
classifier, which grants super fine powders with much higher capacities.

Example products: ATP Turboplex, TTD air classifier.

Circuit-Air classifier
The requisite flow of classifying air is generated by a main fan in the classifier head. A spiral air is generated  
which leads to the separation of the fines from the air flow and discharged usually by means of a rotary  

Example product: Ventoplex air classifier.
