The chute, with a 5’ x 3’ throat opening, is equipped with a unique ore pass insert, isolating the entire installation from upward ground movements. Wabi manufactured the chute to ensure protection against high-stress abrasions and impact forces. Since the chute is used as a main transfer point between the ore pass and a 40-ton capacity haulage truck, its lining system is designed to endure sliding abrasion that comes with high muck stream flow rates. Rapid material loss may occur as a result of sliding abrasion when exposed under high loads, and particularly when the liner plate’s hardness is diminished below the plate’s surface. With the softer core material being exposed, gouges that form in the liner plate caused by sharp contact may result in preferential wear patterns being etched on the surrounding surface.
