A device containing a small amount of explosive, a signal transmitter and in some cases a timing mechanism, usually enclosed in a cylindrical metal shell. It is used to initiate less sensitive or secondary explosives. Modern blasting relies on detonators for the safe and precise control of explosive energy release to achieve desired blast outcomes.Top 5 Companies Involved in Explosives ,Currently, they are essential in fields like construction, mining, engineering, and quarrying.
