The VIRA engineering’s Air Classifier incorporates a self-contained fan and rejecter blade classification system. Its internal fan design does not require cyclones, air locks or dedicated baghouse for product collection of particles in the range of 60 to 350 mesh. Completely self-contained, requires no process dust-collection equipment
Powder feeding hopper mounted on the top of machine. Powder feeding tube is mounted co-axially inside the vertical hollow shaft. Hollow shaft is supported by heavy-duty bearing which is fitted in housing. Self-contained unit is consists one or two disc with whizzer blades rotate inside cone. Powder distributor disc is fitted bellow lower whizzer hub. Top chamber consists rotating deflector blades. Whizzer blades, Distributor plates, and Deflector blades are driven by motor and produce the internal air circuit. Bearing housing, outer & inner drum, damper, deflector vanes, Upper & lower whizzer cones and fine & tail cone are fixed on main body.
Centrifugal type closed circuit Air Classifier is to separate dry powder into coarse & fine powder. Powder can be separated are from 60-350 mashes. It removes coarser particles like free iron, their oxides, grit, silica, heavy impurities. Alternatively, it can remove fine/light foreign material as to de-dust a product. Deflector blades produce centrifugal force and air current to separate particles and impurities on weight basis.
Classifier is for getting uniform size of powder at out-let. Any powder is fed in Classifier will separate it into coarse and fine powder. It is not grinding any material. Types of material are classified like Cement, Flour, Chemicals, Pigments, food colors, Minerals, Sand, zinc, phosphors , etc.
