Engineering Overview & Design Highlights
Jay Mahakali Engineering & Fabricators (JMEF) designs and manufactures state-of-the-art Industrial Air Classifiers engineered for high-precision particle size separation. Operating dry without the use of water or chemical reagents, our air classifiers efficiently segregate ultrafine, fine, and coarse fractions across industrial minerals, chemicals, and food products.
Working Principle & Mechanical Operation
The machine operates using the aerodynamic drag force counterbalanced against centrifugal force created by a high-speed classifying rotor. As raw pulverized material enters the classification chamber, fine particles are carried inward by the controlled air vortex toward the exhaust cyclone, while coarse particles are thrown outward against the casing and discharged separately through the bottom rotary valve.

Frequently Asked Questions About Industrial Air Classifier
What is the minimum particle cut-point achievable with JMEF Air Classifiers?
Our precision air classifiers can achieve cut-points as fine as 5 microns (1,000 mesh) depending on the material density and feeding characteristics.
Can we process abrasive materials like silica and quartz?
Yes, JMEF provides specialized wear-resistant ceramic lining (alumina tiles) and tungsten carbide coated blades specifically engineered for abrasive mineral applications.
