It looks like you’re referring to mine blasting exploders or blasting machines, possibly from Thomas Instruments or a similar manufacturer. Here’s some relevant information:
Mine Blasting Exploders (Blasting Machines)
These are devices used in mining, quarrying, and demolition to electrically detonate explosives (such as dynamite or detonators). They generate a high-voltage pulse to ensure reliable ignition of multiple charges in sequence.
# Key Features:
– High-voltage output (typically 500V–5000V)
– Capacitor discharge mechanism for reliable firing
– Hand-cranked or battery-powered models
– Safety interlocks to prevent accidental firing
– Used in mining, construction, and military applications

2. Davey Bickford – Specializes in electronic detonation systems.
3. Orica Mining Services – Leading supplier of explosives and initiation systems.
4. CIL Exploders – Canadian brand known for hand-cranked blasting machines.
