Air Classifiers Dealers

The VWC classifiers are efficient dynamic air classifiers with a vertical classification rotor. They are suitable for classifying material between 15 to 80 microns material. Operating with a low pressure drop makes these classifiers very economical in operation. Fewer parts in the classifier means this classifier is economical in terms of the initial investment as well. Adjustability of the secondary airstream and the rotor speed allows for a precise onstream control of the sharp cut-point, which allows you to obtain the particle size desired.

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.

We are instrumental in manufacturing and supplying Air Classifier. The offered instrument is used for separating different sizes of particles from two and more kinds of powdered substances. It makes use of centrifugal force and air currents for separation on the basis of weight of the particles. This machine is built in adherence to the industrial standards.

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

It may be operated in closed circuit with a grinding mill or used in open circuit operation, receiving the feed from hoppers, bins screens. Fineness Control The classifier fineness characteristics are controlled mainly by changing the number, size of whizzer blades or by adjustment of vertical slide dampers. These adjustments can be conveniently made to produce the product of required fineness. Tyco classifiers are capable of delivering fine products from 80–85 % passing 60 mesh to as fine as 99.9% passing through 100 mesh depending upon the material characteristics. Application in Closed Circuit Grinding When operated in closed circuit, combination with a Pulveriser the separator skims off the fines as fast as they are made, so that the mill works only on fresh material without wasting power. The tailings are discharge back to the mill for further reduction. The reground material is returned to the separator with the feed, so that constant circulating load set up between the mill & the separator. The Advantages in using Mechanical Air Separator in Closed Circuit with the Grinding Mill for Producing Closely Sized Finished Products include the Following Positive control of Fineness or surface area, and the elimination of over sized particles. For convenient variation of product fineness, vertical dampers permit wild range changes in fineness, externally while the separator is in operation. Increasing the capacity or output of the grinding mill performance, reports have shown increases from 25-75 % or more. Lowering the temperature of the mill & product. Improvement in grinding efficiency, as in the case of Ball mills where ball coating with the fine material can materially impair grinding ball effectiveness.

Whizzer type classifier fitted with distribution plates, coarse cone, fine cone, etc. offers classification of powders into array of different meshes.  

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.
