Air-Classifier Mills (Screenless) are ideally designed for micron particle size. High air through put unique multi-tip rotor and serrated liners create numerous air-whirls, turbulence and progressive grinding. The direction and speed of the particle is suddenly changed within extremely short period resulting into turbulent collision between particles .This ensures micronised fine & free-flowing product. The great turbulence and high air volume ensures a minimum temperature increase facilitating handling of sensitive materials. The classifier retains coarser particles, while suction fan discharge fine powder to the cyclone separator and dust is collected in the bag filter unit. Rotary Air Lock Valve is recommended for such Mills.
