Detonators

Image

Detonators of different varieties are manufactured in a modern plant using highly sophisticated techniques with built in safety, process control and quality control measures. High quality process technology and precision mechanism with in - built process control and quality control measures ensure higher reliability and superior performance under all conditions. An automated process control at the final crimping assembly using specially designed fuse heads ensures total fool proof in quality of detonators. Special Co Precipitated delay timing precision within the close tolerance to avoid delay time overlapping.

Specific Lengths on specific requirements will be supplied.

APPLICATION
  • ROD - Fired with safety fuse n quarry, well sinking and other areas.
  • EDC - For use in underground coal mines of Degree I seam with permitted explosives.
  • MSDD - For use in non-coal mines, drives cross cuts, shaft sinking, tunneling etc.
  • EDC - Used in quarry, well sinking metal / mineral mines and other non-gassy areas.
  • PDD - For use in underground coal mines of Degree I seam with permitted explosives.
  • HSDD - For use in non-coal mines, cross cuts, shaft sinking, tunneling etc.
