Crushing Rollers For Detonating Cord

PROCESS AND APPARATUS FOR PREPARING DETONATING AND

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.

DETONATING CORD AND METHODS OF MAKING AND USING

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.

The Effects of Blasting on Crushing and Grinding

subjected to blasting by one and by two pieces of detonating cord (1996). For taconite, a substantial reduction in work index was calculated. The reduction was greater for the two detonating cord case than for the one cord test. We have used data about core dimensions and the detonating cord used, found in their paper, to calculate a powder factor.

Initiation TRACE Fire and Safety

Non-electrical detonators or fuse caps are thin metal or paper cylindrical shells, open on one end for the insertion of safety fuse, which contain various types of primary and secondary explosives. They are sensitive to heat, shock and crushing and are designed to be initiated with safety fuse or detonating cord.

The detonating cord (Refer to Figure 2) The lowest core load detonating cord is recommended for use with the non–electric delay detonators, in the shaft sinking applications. The detonating cord has a core load of 3.5g/m of PETN, which is encased in a series of ribbons and yarns for maximum tensile strength and abrasion resistance.
