Rieco Industries Limited

RIECO 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.

Working Principle:
The material to be grinded is conveyed from the hopper to the grinding chamber 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 circulating air stream and return to Rotor for additional grinding.

Features:

• Modern, Economical, simple
• High Pressure Mills for dust explosive materials
• Closed Loop systems in inert atmosphere for explosive, heat sensitive and hygroscopic materials.
• Heat Exchanger based cool grinding system for non-explosive heat sensitive material.
• Grinding and Classifying in one machine with online granulation adjustment.
• Dust free Operation
• Uniform particle size distribution with narrow bandwidth.
• Mills can be provided with Online classifier (Micron separator) to further achieve sharp particle cut point
• Low specific energy requirement
• ACM variant with Independent Drive classifier available for sticky materials.

Safety:

• All RIECO ACM mills are equipped with protection devices for safe operation. These measures include a safety switch on the cover of the grinding chamber. It is thereby ensured that the drive motors cannot be switched ‘ON’ when the grinding chamber cover is open
• The plant is supplied along with a control panel and MCC which provides the necessary interlocks and operating switchess
• The mill and all drive components are mounted on a rigid welded steel frame. All rotating parts are dynamically balanced for smooth operation. There is no need for special foundation.
