Abstract

 

Twin Screw Continuous Mixers (TSCM) for processing propellants are gaining more importance since they are safer and offer cost-effective alternative solutions to conventional batch mixers. Presently only a few companies/countries across the world have successfully developed twin screw continuous mixers and demonstrated the continuous mixing technology for processing propellant. However, there is a lag in the use of this technology for processing the propellant in India. This paper describes critical technology challenges, constructional features of TSCM, selection of materials, the evolution of geometry of mixing elements, the potential applications of TSCM in other areas, and the various safety features to be considered during the design, and also how these safety features are incorporated in the design of Twin Screw Continuous Mixer developed by CMTI.
