crushing rollers for detonating cord

PROCESS AND APPARATUS FOR PREPARING DETONATING

Another length of the detonating fuse was removed before passing through the crushing rollers, and then tested for detonating ability. The fuse detonated only 7 inches out of a 16 inch length, thus evidencing the importance of crushing, in imparting the necessary sensitivity to the fuse.

A Few Timing Concepts – Quarry

02/01/2012  Electric pyrotechnic delay detonators (circa 1900) and cord initiating systems followed. Second interval delay detonators entered the market in the 1920s. Each progression of detonator type had its pros and cons, with many mines around the globe still choosing detonating cord on surface for their large-scale paddock blasts, as it is viewed as a cost-effective form of initiation.

As well as the detonating cord, many canopies unlock at the front when the ejection handle is pulled. The airflow gets under the lip of the canopy and tears it off the aircraft. The hinges at the back are designed to break in this scenario. Other canopies have explosive charges which detach the canopy. The Harrier, amongst other examples, might require the pilot to eject at zero or low forward ...

CA2410465C - Detonating cord and methods of making

The velocity of detonation of an explosive such as detonating cord (18, 22) is controlled by the addition of a diluent to the explosive, e.g., to the core of the detonating cord (18, 22). An explosively inert diluent, or a diluent comprised of an explosive of lower brisance than the principal explosive comprising the core of the detonating cord, will serve to reduce the velocity of detonation.
