Introduction of Machine
Premium Airoclassifier mill applies impact grinding and air classification in one step. The mill uses air flow to convey feed material to the mill’s grinding chamber, classifies the material into fine and coarse fractions, recirculates the coarse fraction for further grinding, and conveys fine particles out of the mill, all in one continuous operation.
Another benefit of the PREMIUM AIRO CLASSIFIER MILL is its versatility. Not only can the mill grind a wide range of materials, including fine chemicals, minerals, food products, but the mill’s large air flow volume makes it well suited to grinding heat-sensitive materials. The incoming air flow can be heated to help dry moist materials or conditioned to control temperature and humidity for handling heat- sensitive or hygroscopic materials. The mill can be operated in a closed-loop system to allow the conditioned air to be recycled or so that nitrogen or another inert gas can be substituted for air when handling a potentially explosive
Operational Principal of Premium Airo Classifier Mill
The material to be ground is conveyed to the grinding chamber through feed hopper by variable feed screw mechanism. Hammers provide high impact on the material at high velocity against liner, thus causing disintegration of material to higher fineness. The primary air stream, which enters from below the rotor assembly via baffle ring, flowing up the inner wall of the liner, carries, the particles upward via shroud ring and then deflected by the dispersion ring into the separa- tor wheel. In this section two forces opposite of each other affect each grounded particle. The suction force caused by flowing air and the centrifugal force caused by the rotation of separator. If the suction force is prevailing, the material is discharged with the primary air stream as finished product. If the material particles are not yet fine enough, the centrifugal force prevails, then particles are rejected by the separator and thrown back into the grinding zone by means of the secondary air stream. Acceptable fines pass through the separator because of the suction created by the fan on discharge side and collected efficiently in the pulse jet dust collector and then discharge through rotary air lock valve.
