Centrifugal classifiers.jpg)
Air-centrifugal classifiers with a dynamic area of separation (КЦ) are applied to obtain fine-dispersed powders of a prescribed fractional composition within 2 up to 80 mkm size-range.The operation of a classifier is based on separation of material into coarse and fine fractions at the cost of interaction between the field of centrifugal forces and the air flow.
The regulation of separation products size is done by variation in rotating speed of the accelerating rotor and also by change of the amount of the air flow.
Classifiers of this type are used to obtain high quality filler ma-terials, pigments, high-brand cements, micro-talc and other materials.
The running of classifiers during a number of years has shown their high effectiveness, reliability in operation and simplicity in ser-vicing.
Air-centrifugal classifiers with a static area of separation (КС) are applied to obtain fine-dispersed powders of a prescribed fractional composition within 63 up to 400 mkm size-range.
The separation of material takes place owing to the interaction between the centrifugal force and that of aerodynamic resistance which have an influence upon a particle of the material. Going through the tangen-tially installed blades a powder-gas flow begins to twist. Coarse particles are thrown off on to the periphery of a classifier under the influence of centrifugal forces and then they are sinking along the walls whereas fine particles are carried away from the classifier by the air flow and then they deposit in cyclones.
The regulation of separation products size is done by the change in the angle of installing of adjust-able blades and in the amount of the air flow.
Classifiers of this type are applied, as a rule, in combination with the mills for the reduction of ore materials and non-metallic materials.
