Cascade-gravity classifiers are applied to separate coarse-dispersed materials into the pre-assigned fractions in the size-range between 0,16 up to 5,0 mm.
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 400 mkm size-range.
At present there is an extensive number of tasks to separate materials into several fractions of different sizes. To complete the tasks SPA “Center” specialists have developed classifying complexes of different kinds.
