Mincon Envirosafe Tri-Lube is specifically formulated for blasthole drilling using rotary drills. Envirosafe Tri-Lube is an environmentally safe, high lubricity, water soluble lubricant, designed to extend the life of air bearing roller stabilizers, drill steel and rotary three-cone drill bits. It is injected into the air or water line at a rate of 1.5 liters (3 US Pints) per hour. Envirosafe Tri-Lube reduces downhole torque allowing joints to be broken easier, thus extending the life of the drill steel. It also reduces bit retipping by transferring heat from the cones and lubricating the cutting edge. Envirosafe Tri-Lube prevents corrosion of tanks and lubricates injection pumps, seals and hoses.
