It is important to incorporate high-quality mining wear parts on underground equipment that is constantly exposed to corrosion and abrasion
Due to excessive heat and friction involved in mining, corrosion and wear is one of the most prevalent problems in the industry. Millions are lost due to halted productions, worker injuries and unscheduled repairs as a result of wear and corrosion on equipment. Although replacement and repairs are an inevitable part of maintaining mining equipment, there are ways to minimise losses for continuous usage under harsh conditions. There are a number of methods that can slow down the effects of wear and corrosion particularly for crucial parts such as heat-resistant steel castings.
Choice of Material
The best way to ensure that parts will hold up against the pressure is to make them with excellent materials. Aside from strength, dent resistance, toughness and ductility, heat resistance should be a top characteristic for materials. Crafting parts using such materials will help improve its ability to resist breaking or wearing down under extreme temperatures.
The equipment used by miners in Ontario are subject to constant friction, tension and compression, which means wear and tear on exposed parts. Continuous use of production equipment regardless of the condition of worn parts can have a huge impact on productivity. Besides failing to extract sufficient amounts of ore, they may eventually break down, resulting in costly downtime.
Mining companies use different techniques to keep their equipment and machines in top condition amidst the pressure they are exposed to throughout each operation. Some of these are the same practices that help prolong the life of more common equipment such as automobiles.
With the Ontario mining industry’s growing demand for improved safety, manufacturers of wear resistant castings for underground equipment requirements must ensure that their products are built to the highest of quality standards. The parts produced by these manufacturers play an important role in providing miners with dependable and high-performance equipment that will keep them safe.
Mining equipment manufacturers and Ontario foundry specialists like Wabi Iron & Steel Corp. have product engineers who are experts in designing safe and reliable products. Some of these companies also have advanced on-site laboratories that help them create customized solutions for specific customer requirements. These firms can address most any abrasion, impact, and heat-resistant casting need for the manufacture of impactor parts, crusher parts, pump parts, chute liners, track pads, mine car wheels, and many other products.
Wabi Iron & Steel Corp. supplies high-chrome abrasion-resistant iron pump parts like casings, suction elbows, suction liners, impellers, and suction covers for original equipment manufacturers (OEMs) Yeomans Chicago Corporation and Pentair Pump Group. The quality wear resistant castings are crafted at Wabi’s Foundry Division that specialises in services like electrical discharge machining as well as static and dynamic balancing.
De Beers Canada operates two diamond mines in Canada. One of these is the Victor Mine, an open pit facility that produces approximately 600,000 carats yearly. Through reverse engineering, Wabi’s specialists will be able to determine the correct dimensions, materials needed, and production operations required to build the needed castings. The process of reverse engineering enables a customer who initially does not have an associated drawing of a specific casting to subsequently acquire a drawing which enables them to access product supply directly from a castings manufacturer.
The Vincent Mine is in need of two castings: the Sizer Top-Cap and the Breaker Block. The Sizer Top-Cap weighs at least 190 pounds and is considered as the initial wear portion of a continuous mining machine; in cases of extreme wear, the tip or the entire top-cap might require replacement.
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.
The large-scale development of industrial smelters on the mineral-rich archipelago has put Indonesia in the spotlight for more than just metals producers wanting to take advantage of the country’s rich ore deposits. With smelters being built in quick succession on the islands, wear resistant castings manufacturers are keeping an eye on the archipelago as well.
Due to the incredible amount of maintenance required to keep smelters producing at peak capacity, manufacturers of heat resistant casting solutions are positioning themselves to support Indonesia’s young smelting industry. Given what’s at stake, being able to offer durable, long-lasting, high-performance wear parts for industrial smelters is the name of the game.
Mining companies must invest in efficient wear resistant castings from companies like Wabi Iron & Steel Corp. for their pipeline operations, especially in relation to pump casings, impellers, sideliners and other wear parts. They should ensure that the impact and corrosion resistance characteristics of such equipment can effectively meet their requirements.
Many systems also involve coating the pipes in various materials that could keep the abrasiveness of minerals passing through them at bay. One such system involves coating with a lining of polyurethane with a high performance property. This also helps ease the burden of maintenance and constant repairs.
