Product Details:

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.

Product Details:

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.

Product Details:

Phenol Formaldehyde Resins are prepared in special reaction vessels called kettles by reaction of phenol with formaldehyde in the presence of acidic or base catalyst at 120 °C. The product formed is liquid Phenol-formaldehyde, which is then collected, and air cooled in large trays beneath the kettles, thus the product obtained is rigid and brittle. This rigid product solidifies throughout the trays and needs to be broken manually. Further, we offer solutions for handling and fine grinding of dry phenolic resins.

Dry phenolic resins of 4-10 inches can be pre-cut in Heavy duty crusher to the size of 5mm and less with capacity a range from 500-2000 Kg/hr. Further, these pre-cut resins are formulated with hardener, binder, and fillers in our high efficiency pre-blenders (Ribbon blender) for homogenous mixing. Ribbon blenders are designed to achieve maximum efficiency at minimum power consumption. These homogenous mixtures are transferred further for fine grinding to the Air Classifying Mill (ACM). ACM helps in achieving uniform particle granulation with narrow bandwidth which is most suitable for phenolic resin application. ACM can be provided with Heat exchanger system for cool grinding to take care of the hygroscopic and heat sensitive nature of fine phenolic resin powder. ACM intakes feed size of 3-7 mm & less and delivers output fineness of 99% pass 200 MESH BSS. The fine grounded product is pneumatically conveyed to the product collection system (High efficiency Bag Filter) ensuring dust-free operation complying to stringent pollution norms.
