Later, the aggregate industry and Sturtevant realised that if the whirlwind air classifier was used in an open circuit, the coarse discharge could be recovered as the dust-free main product. Hence, a new use for the whirlwind air classifier was born, giving many sand producers a choice between wet washing and dry washing.

The throat air classifier is able to classify the feed into three different products: the primary product is a manufactured sand with an improved particle size distribution to be used as fine aggregate in concrete, the secondary product is the coarsest fraction of the dust removed from the feed and the tertiary product is the finest fraction of ...
Several types of Zigzag classifier are produced by Alpine [5] for separation of ferruginous ore, fertilizers, plastic, wooden dust, etc. at cut sizes ranging from 0.1 to 10. mm.. The number of parallel chambers varies from one to 16 with output ranging from 1 to 10 t/h.Although multiple scavenging improves separation, coarse particles crossing the …
Conventional air classifiers have in general cut sizes of above 1 μm (ϱs = 2710 kg/m3). The development of new and better products, for instance in the toner industry, depends on the possibility ...

for heavy met-als, depicted in Figure 1. Dry sepa-ration methods can basically be bro-ken down into three main types of mechanical separation procedures: air classification, s. reening and specific-gravity separation. Process engineers are routinely challenged with the ubiquitous problem of how to most effectively and efficiently perform ...
In precise dry classification of different fractions of sand, a complete solution for separation and dust collection is needed.

Air classifier effectively combines gravitational, and aerodynamic forces to classify materials at cut points, ranging from 5 to 200 mesh (300 to 75 microns) for concrete sand. Dry classification is innovation over wet classification method, which is more environment friendly, as there is no water wastage and is much more economical due to the ...
Fine powder separation equipment. Fine powder separation equipment operates by one of two mechanisms: mechanical separation or air classification. Mechanical separation uses screens that allow small particles to pass through while holding back and redirecting oversized particles. Air classification uses airflow to separate …
Air classifiers are normally employed when dry material particle size for separation is too fine for screening. The beauty of an air classification system is that it defeats the blinding and breaking issues associated with screening. The most significant advantage is its dry process for de-dusting aggregates.
