The material to milled is led out of the feed hopper by a mechanical feed dosing device into the feed inlet or suction spout of the mill. The rate of feed needs to be controlled for ensuring a uniform trickle feed so that uniform milled product is obtained without blocking or overloading the mill. Suitable controls are provided with the mill.

In the feed inlet of the mill a strong permanent magnet can be provided to catch hold of any ferrous tramp matter. The feed material mixed with a quantity of air aspirated by the running of the mill rotor, enters the milling chamber near the central axis of the rotor. The material is hurled vigorously outwards toward the periphery of the rotor by centrifugal force and progressively reduced in size by the milling rotor till it reaches the circumferential sieve ring. After passing the sieve ring the milled powder has to be separated from the accompanying air.

The degree of fineness achieved will depend on the nature of product, type rotor and the sieve ring fitted. It is also influenced by rate of feed, the quantity of air sucked into the mill with the feed and the peripheral speed of the rotor.

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.

Micro Pulverizer is a rugged, high efficiency grinding unit which grinds variety of products from granular to fine grinds economically. Built with an eye to precisely achieve controlled particle size, this Mill provides high production at low cost. Micro- pulverizer can easily be designed for variety of materials and output capacity ranging from 50 – 4000 kg/hr. Micro-pulverizer can be used as standalone machine or integrated with Dust collection system to ensure dust free operation and enhanced yield. GMP grade machines can be supplied for Pharma and Fine chemicals.

All RIECO Micro-Pulveriser consist of a rotor assembly, fitted with hammers generally operating at a high speed; a cover fitted with either a multi deflector or plain liner; a retaining screen at the point of mill discharge and a feed screw mechanism whereby the unground material is uniformly fed to the grinding chamber. The grinding action in Micro Pulveriser takes place due to impact between rapidly moving hammers and the particles on liner.
