Air Classifiers

Our classification systems are employed in a wide variety of applications, products and fineness ranges. Whether this is to be employed as an individual bought out equipment to be incorporated into your existing system, or in a closed-loop classification and grinding circuit, our classifiers will economically meet your application and yield the desired result.


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.

The MWC series are versatile and highly capable classifiers. These classifiers are capable offulfilling the need for super-fine cut sizes at high throughput rates.

MWC classifiers are dynamic separation systems which incorporate multiple horizontal classifier rotors. Manufactured to precise tolerances, these rotors ensure a wear and maintenance free operation. The classifier rotors are provided with VFDs to regulate the speed based on the cut size desired. Easy setting of the rinsing gap allows for a hassle free operation.

The MWC classifiers work in conjunction with a second separator to discharge the coarse particles into a separate channel by supply of another cyclonic airstream.It is possible to classify extremely fine products in the range of5 8 ┬Ám.


  • For materials that are highly abrasive in nature, classifiers wheels are provided with suitable protective coatings. Lining can be provided on other contact parts as well.
  • For applications involving food or pharmaceutical material, the classifier can be provided in full buffed stainless steel construction.
