Air Classifiers Dealers

Features Strong construction of mechanism and casing ensures long life. Close control over product uniformity. Minimum loss of fines in the tailings. Special liners are available for processing abrasive materials. Advantages The Air Classifier is a centrifugal type classifier used to separate dry powdered materials into fine and coarse fractions. It may be operated in closed circuit with a grinding mill or used in open circuit operation, receiving the feed from hoppers, bins screens.

When material particle size is important for end product performance or further processing air classification offers separation by particle density and diameter into the required fractions or regular screening machines are not satisfying the the accurate classification need, Air classifier comes into the role. Selection of the right air classifier and specification of the most appropriate model is crucial if accurate end product characteristics are required.Umatech Micron has developed two types of Classifier : Whizzer type Classifier and Dynamic type Classifier.Umatech Micron Whizzer type Air Classification is an airstream classifier where the feed material is pneumatically or with screw fed to the unit and is used in the medium to fine range of classifications, 20 - 150 microns, with high separation ration. Umatech Micron Dynamic Air Classification is an airstream classifier where the feed material is pneumatically fed to the unit and is used in the medium to fine range of classifications, 2 -20 microns, with high separation ration. The Umatech Dynamic Air Classifier is frequently operated in closed circuit with ball and table roller mills. Typical application is in the minerals field for; Limestone, quicklime, fertilising lime, bentonite, dolomite, gypsum, quartz and feldspar, silica, ceramics and other chemicals also. Abrasive materials can be processed by wear protecting the internals. The relatively slow speed also helps this. Whatever your powder classification need, Umatech Micron can supply the best solution.

Features:   Particles are reduced to finer and more uniform sizes. Use of cyclone separator leads to less dusting on output side. No dusting from feeding hopper because feeding is done under negative pressure. It runs at lower speed , hence it requires much less maintenance. They are easy to clean & wash. It is manually fed as normal practice & can be supplied with automatic feeding as well. It uses air classification which does not require screen. Hence, it is free from problems like conking, Printing & frequent replacement of screen do not arise.

We are offering fab ultrafine classifier. Applications the fab ultrafine classifier produces fine powders by separating a defined grain size from a fed turbulent air flow by creating a “virtual” mesh with a fast rotating classifier wheel. The suction force of the air stream normally produced by a ventilator forces the fine particles though that wheel into a filter where the particles are separated from the air stream. The coarse particles fall down and are washed out again through new incoming air and feed material. the classifiers can be fed from below for fine applications and for coarser classifications the material is fed from the top using the gravity force and covers so a wide range of possible cut-points. the internal geometry of the machines a final product with hardly no coarse particle contamination as well as a continuous process. features and benefits: · operating particle size range of 1 to 150 microns · very high efficiency · minimum undersize returned in product oversize · lowest specific energy · low pressure drop · compact design. · effective particle distribution · easy access and cleanability.

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.Know Process of AIR CLASSIFIERMaterial fed into inner tube from inlet hopper. Rotating distributor plate distributes powder radilly outward into upward sweep of circulating air stream generated by deflector blades. Every particle is got downward gravity force and upward air stream force. Gravitational force is higher on grits and impurities due higher weight. Upward air stream force is not enough against gravity force. Particles prevails gravity force than flows downward force and pass it through tail cone. Light weight (fine) particles move upward because air stream force is more than gravity force on it. Both raw of Whizzer blades are provide to adjust resistance to particles by add/remove blades. It helps to reduce or increase the escape of particles towards deflector blades. Whatever Particles pass through both whizzers will discharged into circular space between inner and outer drum due to centrifugal force and discharged through center fine cone. Air after releasing fine in outer cone returns through the deflectors vanes to the inner cone, setting up a continuous air circuit. Thus heavy particle discharge through tail cone and fine are through fine cone. Fine and coarse grade separation ratio is varying from 95-5 to 60-40. Pattern of classification can be change by regulation and controlling air stream. Air stream can be reduced by closing air dampers and increase by opening. Dual purpose is removing heavier impurities for better quality and removes grit of particle for better size distribution. 

These Clasifiers have been developed specially for achievement of below 40 micron down to 8/10 micron or finer particles. Best yields at very low specific energy consumption can be achieved. Various options are available such as stainless steel construction / ceramic lining against corrosive and abrasive materials. We can run semi-industrial tests in our test facility
