ISRO , in collaboration with the Central Manufacturing Technology Institute ( CMTI ) in Bengaluru, has developed the world's largest 10-tonne vertical planetary mixer for processing solid rocket propellants. Handed over to the Satish Dhawan Space Centre (SDSC SHAR) in Sriharikota, this milestone boosts India's self-reliance under the Atmanirbhar Bharat in Space initiative. Purpose : Precision- blends sensitive solid propellant ingredients (such as ammonium perchlorate, aluminium, and binders) to ensure uniform composition, high structural quality, and reliable thrust for heavy-lift launch vehicles (like PSLV and GSLV)
