Maxfire igniters

MAXFIRE IGNITERS

Maxfire is the first ever 1.4S pyrotechnic initiation system with timing capability. It is also the foremost electrical or shock tube based system providing powerful initiation of propellant cartridges.  Timing/delay initiation has previously only been possible with conventional detonators. Delay precision is equal to traditional detonator systems.

The Maxfire initiation system features a highly accurate delay element encased in each igniter. Therefore it is possible to delay individual holes, or sets of holes, and thereby initiate the Royex propellant cartridges in a pre-determined sequence. Numerous delay sequences are available allowing the coordinated blasting of complete panels and development ends. No other system in the world is capable of this versatility.

Initiation heat and pressure is essential for the performance of non-detonating cartridges. The Maxfire initiation capability is the most powerful available on the global market today and this feature enhances the reliability and efficiency of the Royex cartridge making the Royex system cartridge the most powerful deflagrating cartridge available worldwide.

Maxfire igniters are connected and fixed into the Royex cartridge using a wingnut screw fitting that smoothly connects with the Royex igniter plug. The connection is secure and waterproof, ensuring that the igniter is firmly connected into the cartridge and in place during the loading and stemming operation.

Royex initiation machine Bart 1

Royex Initiation machine BART 1

BART-1 is a medium energy hand cranked blasting machine that comes with a built-in line continuity tester. It uses a hand generator and the operator does not need an external power supply or batteries. The blasting machine is portable, compact and lightweight, and can easily be operated by a single person.

The integrated line tester verifies the line’s integrity and uses a two color LED that indicates to the user whether the resistance of the line and igniters/detonators is below or above 700 Ω.  For safety reasons, the line tester current is limited to 1 mA.

BART-1 includes an output pulse tail cutting to limit the impulse to 4ms and quench the remaining capacitor charge. These safety features are necessary to eliminate potential secondary explosions of the flammable dust generated during the blast.

The device comes in an aluminum enclosure that includes ON–OFF/L-test switch, terminal for connection of electric igniter/detonator lines, two color LED for line testing and a crank handle for capacitor charging. Both sides of the panel include “READY” LEDs to indicate the capacitor charge state.

Royex Initiation machine BART 2

BART-2 is a powerful high energy hand cranked blasting machine. The device uses a hand generator and the operator does not need an external power supply or batteries. The blasting machine is portable, compact and lightweight, and can easily be operated by a single person.

BART-2 can be used to initiate up to 80 Maxfire igntiers or detonate most insensitive electric detonators that require high energy to detonate, including class C4 highly insensitive detonators.

BART-2 includes an output pulse tail cutting to limit the impulse to 4ms and quench the remaining capacitor charge. These safety features are necessary to eliminate potential secondary explosions of the flammable dust generated during the blast.

The blasting machine includes a number of important safety features to avoid accidental initiation. The crank handle can be removed by the operator when the firing line and the igniters/detonators are inspected or not ready to be fired yet. BART-2AS also includes a mechanical safety cover above the terminals that prevent cranking when the line is connected. Lastly, there are two FIRE buttons that need to be pushed simultaneously for initiation.

The device comes in an aluminum enclosure that includes ON-OFF/L-test switch, terminals for connecting electric firing line, and a crank handle for capacitor charging. Both sides of the panel include “READY” LEDs to indicate the capacitor charge state.

ROYEX SURESTEM CLAY PLUGS

The Royex surestem clay stemming plugs are ideal stemming material for horizontal or up  holes. The clay consistency is specifically selected to ensure excellent blast  confinement while maintaining a mouldability and low water absorption content.

The surestem plugs are ideal to be used in  conjunction with the Royex cartridges for horizontal or up holes. The plugs are packed in fine paper and  offered in 43 x 150 mm with a weight of 450 gram each. They are sold in a case of 45 units totaling a weight of 22 Kg. 

Custom sizes, consistency and dimensions can be made to fit client needs.  

THE ROYEX HOLE IRON

Made of purpose matched steel, the hole iron is applied at the end of the drill hole and ensures that the gas energy is contained and propagates through the rock rather than out of the drill hole. This minimizes the risk of hole blow outs and ensures optimum results, even in drill hole depths as short as 60 cm. The product is especially useful in dimensional stone quarrying where straight cuts are needed and where normally shallow blast holes are used.

The Royex hole iron is made in two sizes, 32 mm and 25 mm for drill hole diameters of 35-40 mm and 28 – 32 mm respectively.

Royex initiation machine Mars 2

Royex Initiation machine MARS

MARS-2 is a medium energy blasting machine that comes with a built-in digital line tester. The blasting machine is portable, compact and lightweight, and can easily be operated by a single person.

The integrated line tester measures the  firing line resistance to identify short circuits, breaks in the blasting line or circuits with excessive resistance prior to the blast. For safety reasons, the line tester current is limited to 1 mA.

MARS-2 includes output pulse tail cutting to limit the output pulse to 4 ms and quench the remaining capacitor charge. These safety features are necessary to eliminate potential secondary explosions of the flammable dust generated during the blast.

The device comes in an ABS enclosure and includes push button switches, terminals for connecting electric detonator line, digital LCD screen for line testing and LEDs showing the state of the capacitor charge and the battery level.

For safety reasons there are two FIRE buttons. The operator has to push both buttons simultaneously for initiation.
