TROJAN® RINGPRIME
|
TROJAN RINGPRIME cast booster is a detonator sensitive, high density, high energy molecular explosive, cast into a plastic shell. It has a single tunnel and capwell located centrally in the booster which will accept both NONEL® and DigiShot® Plus or SmartShot™ electronic initiation system detonators. TROJAN RINGPRIME cast boosters are formulated from the highest quality PETN and other high explosive materials ensuring reliability, consistency and durability in underground environments. In addition, the top of the TROJAN RINGPRIME wells are recessed to protect the initiation line from damage and the recessed bottom allows the insertion of a loading hose to assist in positioning the primer in the borehole.

APPLICATION RECOMMENDATIONS
• The TROJAN RINGPRIME cast booster is specifically designed for use in underground angled or vertical upholes. It is ideal for priming 64mm (2.5 in) to 159mm (6.25 in) upholes loaded with ANFO, cartridgde or bulk emulsion products.
• ALWAYS snap on the spider assembly and insert the detonator through the tunnel and into the cap well. Insert the loading hose into the recess at the bottom of the TROJAN RINGPRIME and gently push the assembly into position using the loading hose. The spider legs will lock into the side of the phole and secure the TROJAN Ringprime in place.
• ALWAYS maintain a firm grip on the NONEL® tube or leg wires while loading to prevent the loss of the initiation line.
• Minimum detonator is No. 8 strength for temperatures above -40º C (-40º F). A high strength detonator is recommended for temperatures below -40º C (-40º F).
• ALWAYS use detonating cord with a coreload of 10.6 g/m (50 gr/ft) or higher when iniitiating the TROJAN RINGPRIME booster with detonating cord.
• The detachable spider is designed to centrally locate and lock the TROJAN RINGPRIME in the borehole. Other features allow the spider to unlock should the unit need to be retrieved from the borehole.
• Extremely low temperatures do not affect the performance of cast boosters with commercial detonators. Low temperatures do affect detonators and detonating cord. Be certain your initiation system is suitable for your application in extremely low temperatures. Cast boosters are more susceptible to breakage during handling
in extremely cold temperatures.
