Advantages / Salient Technical Features IPR Status / Details (India/Abroad)

• Improved stress intensity profiles Improved lift-off • Agitators of stirred mills for fine and ultrafine
the material resulting in less material settlement grinding applications, App. No. TEMP/E-
Improved/uniform grinding; usable to grinding of 1/59632/2021-DEL, CSIR sole patent
different types of ores
Application/Uses
Problem being addressed • Fine and ultra-fine grinding, Secondary
• The varying characteristics of ores need different and tertiary grinding, Size reduction in
grinding approaches. The different designs of stirrers/ Pharmaceutical industry
agitators as have been developed to address varying
range of grinding such as grinding of hard ore, soft Scale of Development
ore, clayey ore etc. • Laboratory prototypes developed (Current
TRL Level : 03)
Environmental Considerations (if any)
• Utilization of low-grade ores at less energy cost Commercialization Status
addresses the environment concerns of industries • No
Utilization of previously dumped low- grade slimes
Compliance with government norms on extracting Techno-economics
maximum valuables and minimal disposal of tailings • NA
