Air Classifier - Whizzer Type

Air Classification is the process of separating particles according to the settling velocity in a gas. Air Classifiers are used to separate dry materials into different particle size fractions by their size, mass or shape. Air Classifiers are used to modify a particle size distribution, remove the fines fraction of a material or the over size or coarse particles of a material or create two grades of material.

The D. P. Air Classifier is a compact and dust tight machine for fine classification of various powdered materials. The air classifiers are ruggedly constructed to high engineering standards to give long reliable service life to the most arduous duties. Low operating speed ensures that wear and tear is minimised when handling abrasive materials. Easy access to the interior of the machine for inspection and cleaning is ensured by the provision of generously proportioned inspection doors. The rotor is mounted on heavy duty antifriction bearings which are located outside the machine and protect them against ingress of dust. Due to self contained nature of the machine all air flow is contained with the boundaries of the machine.

Applications

The D.P. Air Classifiers are used for a wide range of applications e.g. Cement, Limestone, Soya flour, Hydrated lime, Food Products, Chemicals, Talc, Clays, Metallurgical Powders, Pigments, Fly Ash, Silica, Aluminium Oxide, Graphite, Calcined Magnesite, P.V.C. Resin, Asbestos, Barytes, Quartz, Feldspar, Coal, etc.

Outstanding Features
