Our Achievements

We are the stalwarts, who:

  • Indigenously developed GRINDING MILLS and solved challenging size reduction problems.
  • Developed Sulphur Grinding Mill with Inert Gas Atmosphere, the grinding of which is supposed to be highly explosive & hazardous and thus able to develop almost Explosion Free Sulphur Grinding System.
  • Attached Pulveriser in Flash Dryers & gave an Ultrafine dry product in one single operation.
  • Ran the Pulverizer Automatically under maximum yield conditions through our Digital (Automatic) Feed Controller.
  • Designed and developed ‘Free Silica Separation System’ & Static Classifier in Pulverizer which resulted in minimal quantity of Free Silica & Grits in product.
  • Separated metal from it’s dross during Grinding.
  • Designed and developed equipments especially for Pesticide industries which are supposed to be very complicated and thus have played an important role in “THE GREEN REVOLUTION”.
  • Converted Pulveriser in to Open Circuit Grinding by attaching Reverse Jet Pulse Air Bag Filter thus reducing power consumption to almost 50%.
  • Designed and developed continuous drying system for the drying of Phosphorous Penta Chloride.
  • Designed & developed cooler grinding system for the spices grinding thus protecting all volatile matter during grinding operation in the end product.
