APEXCEL TLD (Trunk Line Delays)


Description

APEXCEL TLDs are non-electric initiating devices used for surface initiation in blasts to provide necessary delay between the holes in rows and between the rows. APEXCEL TLD consists of a shock tube with a delay detonator with a suitable bunch connector at one end and the other end is sealed. The bunch connector has the provision to hold six tubes for initiation. The bunch connectors are colour coded to indicate the delay timings.

Advantages

1. Surface air blast is completely eliminated.
2. Use of detonating cord or cord relays is eliminated
3. The bunch connectors are user friendly and allow for easy on-site connection for the blast
4. They provide accurate delay per hole by improving muck file profile and thereby increase the fragmentation and overall blast performance.
