Air classifying of dry powders
Due to their particle size distribution, some processed products still do not meet application requirements. Fine fractions or oversized particles interfere with further processing or make the final product unsuitable for the targeted application.
Such products require additional "optimisation" to meet the desired particle size distribution necessary to improve the product's characteristics. Customarily products with a particle size range of > 100 µm can be classified without difficulty using a screening machine, however, air classifiers are essential for finer particle size distributions that require a more controlled separation.
Typical applications for our fine classifiers are the separation of undesired coarse grains and the distinct reduction of fines (de-dusting).
Different machine designs are available, depending on the desired cut points or application. Machine sizes are available for nearly all ranges of capacity. We carry out the project planning, production and commissioning of individual machines as well as complete classifying plants.
When a screening machine cannot be used, due to its separation limitations:
With our „standard“ ultra-fine classifier, CFS, fine powders can be cleanly classified. High performance classification and efficient results are valid for both coarse material and the separation of fines.
Available for finenesses from 10 to 250 µm (d97).
Machine sizes available for gas volume from approximately 50 to 16.000 Nm3 h-1.
CFS Ultra-Fine Classifier
The requirements of many product applications such as improved separation sharpness and finer cut points, are no problem for the CFS/HD-S range of CONDUX High-efficiency Fine Classifiers.
Thanks to the maximum predispersion of the product to be classified, the targeted cut point and sharpness of cut can be optimized distinctly.
Available for finenesses from 2.5 to 60 µm (d97).
Machine sizes available for gas volume from approximately 50 to 16.000 Nm3 h-1.
