INAUGRATION OF VERTICAL PLANETARY MIXER AT DRDO'S ADVANCED CENTRE FOR ENERGETIC MATERIALS (ACEM)
Dr S Christopher, Secretary, Department of Defence R&D and DG DRDO, inaugurated the largest Vertical Planetary Mixer (VPM) of 3000 litre capacity in Advanced Centre for Energetic Materials (ACEM), Nasik, on 26 October 2015. Speaking on the occasion, Dr Christopher congratulated the team ACEM for the achievement in self-reliance and urged to gear up for future challenges.
The mixer, built by Central Manufacturing Technology Institute (CMTI), Bengaluru, is first of its kind in the country and is equipped with three agitators made of CF8 steel with helical flute design. A heavy-duty flame-proof electrical motor of 80 kW with VFD drive rotates the agitators in controlled axial and planetary motions that can mix propellant slurries of high viscosity (up to 1,00,000 Poise) in change-can bowls. Safety mechanisms for protection of overload, over-current and bowl overpressure and over-torque are included in the design. A PLC-SCADA-based automation with redundant HMI ensures remote operation of the VPM. The indigenously designed and . manufactured mixer will facilitate solid propellant processing for large boosters.
Dr S Christopher also inspected other important facilities like Nitramine Grinding and Spheroidisation Plant (NGSP), Air Classifying Mill (ACM) for oxidizer, Rocket Motor Hardware preparation, Propellant Casting and Curing Facility and MAGNDT. Scientists of ACEM explained various operations involved in the processing of composite solid propellant and their criticality.
