RIECO’s Air classifier Mill (ACM) is an air classifying mill with integrated grinding, classifying, conveying, and collecting operations for achieving ultra-fine grinding (up to 2 micron*) depending upon the nature of the product.
Air classifying Mill / Air classifier Mill (ACM) can be designed for grinding hygroscopic, heat sensitive and explosive materials in inert gas/ closed loop systems with dry chilled air. Our classifiers are engineered to consistently produce steep particle size distributions that are uniform and homogeneous.
The material to be grinded is conveyed from the hopper to the grinding zone by the variable feed screw mechanism. The grinding occurs when the product meets a pin or bar type rotor disc. As particles are reduced in size they are entrained by the Air stream which enters below the rotor and are carried up between the inner wall and shroud ring with baffles, the particles are then deflected by an air dispersion ring to the separator assembly. Acceptable product is drawn through the exhaust and is collected by a high efficiency bag filter. Oversize particles are carried downward by internal air classifier and return to Rotor for additional grinding.
