Powder Process Design Services Limited

Air Classification

PPDS supply air classifiers both for operation in conjunction with mills and for the independent classification of powders.

We offer new and used classifier solutions for a wide range of throughput and fineness options. Feed capacities from laboratory scale up to 50 tonne/hour can be catered for with separations ranging from 90% passing 250 micron down to 97% passing 5 micron are possible.

Design options are available for the processing of abrasive materials where a combination of PU and alloy steel are used to protect the areas most susceptible to wear. We can also offer solutions on applications where iron contamination must be avoided.
