Micronizing plant for minerals

We have developed a range of import substitute Air Classification Plants for processing various minerals to produce a wide range of micronized grades of minerals like Calcite, Dolomite, Talc, Barytes, China Clay (Kaolin), Mica, Silica etc.

These plants are designed to efficiently separate the fines and coarse oversize particles from the feed material of 300 to 500 mesh powder. The conventional mechanical grinding using either a Pulveriser or a Raymond mill can economically produce powders up to 300/500 mesh size only which generally have a top cut of 50 to 35 microns and average particle size of 20 to 15 microns. Our plants are capable of producing complete range of micronized mineral grades having top cut of 20, 10 and 5 microns having mean particle size of 5, 3 and 1.5 respectively with sharp cut accuracy. Micronized grades of various minerals have good demand in various industries like Paints, Power Coating, Ink, Plastics, Paper, Rubber, Pharmaceutical, Ceramics, Cosmetics, Construction Chemicals etc. In all these industries, the finer the powder the better it is from the processing point of view as well as for the quality of the end product. The process have twin benefits, the Classified products are sold at much higher price to the conventional ground minerals powders (feed product to the Classification Plant), whereas the coarse separated from the fines is sold as a coarse product. Hence, practically no wastage or by product is generated in the Classification process.

Air Classification Plant INTEGRATED with Continuous Ball Mill (CCG)

For optimization of the Classification plant performance by way of better recovery of micronized grades and reduce the generation of the coarse material, we recommend our Continuous Ball Mill (CCG) having Close Circuit Grinding System duly integrated with the Air Classification Plant.

 

Commercial as well as Qualitative advantages

✢   Compared to a Pulveriser or a Raymond mill grinding system, a Ball Mill generates 15-20% extra fines.
✢   Being Close Circuit Grinding system, the coarse rejected from the Classification plant are redirected to the Ball
      Mill for further grinding. Hence, the low value coarse reject from the Classification plant is reutilized.
✢   Lower Primary grinding cost as as instead of grinding 500 mesh only 300 mesh grinding would be required
      for feeding to the Ball Mill. Also the production would be higher.
✢ Overall production cost per MT would go down, due to less initial grinding required in present system, more       percentage of fines being generated in the Ball Mill and minimization of coarse generation.
✢   In case of product blending/coating a more homogeneous and consistent mixing is achieved with Ball Mill
      compared to conventional grinding/mixing system.

Hot air continuous dryer for China Clay

We have designed a customer specific Continuous Duty Slat Conveyor type Hot Air Dryer for the removal of the moisture from the China Clay.

The 60 ft. Long conveyor dryer is capable of drying 2MT per hour of China Clay.
