LHU Contraflow Classifier

The LHU Contraflow Classifier is the best choice for the classification of the sticky, aggregated, illiquid and low density material, can separate the superfine powders from 2~150μm efficiency, connected with other classifier also is available.


Air classifier






The material enters the classifier through the air suction device, and the particles are classified by the centrifugal force generated by the classification wheel and the gravity generated by the airflow guide device.


1. High classification efficiency: the ultra-fine particles can be separated from d97 = 5-250 microns most efficiently. Compared with other classifiers, the classification efficiency is increased by more than 30%.
2. Strong dispersion: It is the best solution for materials with viscosity, agglomeration, poor fluidity and light specific gravity.
3. The grading range D97 = 5-100 microns is adjustable.

4. Processing capacity of 0.05-50t / h models is available.
5. It can form online operations with other classifiers.

6. It can be connected with various grinding equipment such as ball mill, Raymond mill, impact mill, jet mill and so on.
