Air Classifying Mill (Micronizer)

ULTRA FINE AIR CLASSIFYING MILL (ACM):
Ultrafine Air Classifying Mills are used for size reduction of various products to microfine particle sizes. The system incorporates integral classifier where the fine particles of desired size are segregated and the over size particles back to the grinding chamber and re-grinded until the desired particle size is obtained. Air Classifying Mill (Micronizer) is very compact and efficient, having sharp classifier cut points which are instantly adjustable. The system incorporates grinding and classification in one single compact space saving design.

SALIENT FEATURES :

• Grinding and Classifying in one machine
• Cool and smooth grinding
• Steep particle size distribution
• Sharp Classifier cut point, instantly adjustable.
• Easy cleaning and maintenance.
• Low specific energy requirement
• Compact space saving design.

PRINCIPLE OF OPERATION :
The material to be ground is conveyed from a hopper by screw feeder or pneumatically fed through Rotary Air Lock Feeder to the grinding chamber of the Air Classifying Mill (ACM). The pins/bars of the rotor break the particles of the material. These particles are entrained by an air stream which enters below the pin rotor and are carried up between the inner wall and the shroud ring with baffles which decrease the air swirl. These particle then enter the classifying section where the fine material is carried out with the air through the classifier rotor to the outlet, the course material is thrown against the shroud rind and carried down to the pin rotor for further reduction. After leaving the micronizer air mixed with fine particles enter the bag filter where the fine particles are separated and the clean air is discharged to the atmosphere.

Application
Air Classifying Mill (Micronizer) is used to ground and classify the materials like Phenolic Resin, Sulpher, Ammonium Phosphate, Epoxy/Polyester resin, Fish Meal, Iron Oxide, Lead Oxide, Carbon, Lime Stone, Melamine Resin, Organic Pigment, Sorbitol, Sulpher, PVC, Talcum, etc.

Jet Mill Micronizer is used for micronizing of solids of agro-chemicals, chemicals, pigments, minerals. Pharmaceuticals, thermoplastics and other heat sensitive, corrosive and abrasive materials.

PRINCIPAL OF OPERATION :
Jet Mill works on micronizing of products using compressed air instead of mechanical impacts due to which the micro size is very fine. Micro milled products are obtained in microns after the material collide with each other and reduce themselves by attrition and collision.

APPLICATION :
Jet Mill Micronizers are used in industries like Agro chemicals, Chemicals, Pharmaceuticals, Ceramics, Metals, Minerals, Paints, Plastics and others like Food Colours, Fuller Earth, Toner, Wax, etc.
