![]() | CLQM is one of today’s most widely used grinding machines for reducing dry fine chemicals, food products, and other materials. It combines a mechanical impact mill with dynamic air classifier for middle-small volume continuous processing. After several years experience, it can be customized to different materials.The mill can be equipped with different grinding tracks as well as different impact elements, depending on the product and final product specs. |
Appication of Air Classifier Mill
With over 1000 references worldwide, it is used the most industry:
Chemicals: bisphenol, tartaric acid, E-PVC, fungicides, herbicides, stearates.
Powder coatings: epoxy, polyester, hybrids, UV-curing acrylates, polyamide.
Food: sugar, cacao, starch, fish meal, xanthan, guar flour, lactose.
Pharma/cosmetics: face powder, ascorbic acid, tartaric acid.
Minerals: talc, kaolin, calcium sulphate, bauxite, limestone.

Structures of Air Classifier Mill
CLQM mill mainly consists of the screw feeder, grinding unit, classifier, power section, cyclone,
filter, blower, electrical panel etc. The main motor, mill disc, mill blocks, classifier, inlet liner,
