• High-Performance Threaded Drill Bits:
Luoyang Jinlu Hard Alloy Tools Co., Ltd. has successfully implemented its high-performance threaded drill bits in a major coal mining operation in Shanxi Province, one of China’s largest coal-producing regions. The mine, operating under challenging geological conditions with abrasive and highly variable rock formations, previously experienced frequent tool breakage and downtime due to suboptimal drilling equipment. After switching to Luoyang Jinlu’s precision-engineered threaded drill bits—featuring impact-resistant and wear-resistant mining alloy teeth combined with high-quality, precision-forged steel bodies—the mine reported a 45% increase in drilling speed and a 60% reduction in tool replacement frequency. The enhanced durability of the drill bits, backed by Luoyang Jinlu’s advanced sintering technology and strict quality control protocols, significantly extended service life, reducing operational costs by over 30%. Furthermore, the improved consistency in borehole depth and alignment led to better blast planning and increased coal recovery rates. This real-world application not only validated Luoyang Jinlu’s technological leadership but also demonstrated how innovation in tool design directly translates into measurable economic and safety benefits in high-stress mining environments.
• Durable Down-the-Hole Drill Bits:
In a deep underground coal mine in Inner Mongolia, where drilling depths exceeded 1,200 meters and rock hardness varied dramatically, Luoyang Jinlu’s down-the-hole (DTH) drill bits were deployed as part of a comprehensive upgrade initiative. Prior to the deployment, the mine faced persistent issues with bit failure, leading to costly delays and safety risks. Luoyang Jinlu’s DTH drill bits, engineered with ultra-high-purity tungsten carbide and optimized structural design for high-impact resistance, delivered exceptional performance under extreme pressure and temperature conditions. Over a six-month trial period, these drill bits achieved an average penetration rate of 18 meters per hour—up from 11 meters previously—while maintaining structural integrity even in fractured and abrasive strata. Notably, the bits required no maintenance or replacement during the first three months of operation, resulting in a 52% reduction in non-productive time. The success of this project was recognized by the mine’s management team, who cited Luoyang Jinlu’s commitment to R&D and material science as key factors in achieving such breakthrough results. This case exemplifies how cutting-edge engineering and material innovation can transform deep-mining operations, ensuring both higher output and safer working conditions.

• Thermal Spray Powder for Enhanced Durability:
A prominent coal processing plant in Henan Province faced recurring failures in its crushing rollers due to severe wear caused by high-volume coal transfer. Traditional coatings failed within weeks, leading to frequent shutdowns and maintenance costs. Luoyang Jinlu introduced its tungsten carbide-based thermal spray powder—specifically formulated with WC: 3um and WC: 5um grain sizes—applied via plasma cladding technology. The coating exhibited a hardness exceeding 1,200 HV and demonstrated outstanding resistance to abrasion and thermal fatigue. After implementation, the coated rollers lasted over 18 months without significant degradation, compared to the previous average lifespan of just 4–6 months. This improvement reduced unplanned downtime by 70% and cut maintenance expenses by nearly 40%. The plant’s operations manager highlighted that the superior performance of Luoyang Jinlu’s thermal spray powder not only enhanced equipment longevity but also contributed to more consistent product quality and lower energy consumption during processing. This case underscores the transformative potential of advanced hardfacing materials in extending the life of critical mining machinery and optimizing long-term operational efficiency.
• Self-Fusing Alloy Powder for Superior Performance:
In a large-scale open-pit coal mine in Xinjiang, the conveyor system’s drive rollers suffered from rapid wear due to high-speed coal transport and exposure to dust-laden environments. Luoyang Jinlu supplied its self-fusing alloy powder—produced using vacuum atomization and tailored for laser cladding applications—to reinforce the roller surfaces. The powder, composed of cobalt-based and nickel-based alloys blended with cemented carbide particles, formed a dense, crack-free coating with excellent adhesion and impact toughness. Post-application testing revealed that the reinforced rollers withstood over 2 million cycles of load without visible wear, far surpassing the performance of standard alloy-coated rollers. Additionally, the coating maintained its integrity even after exposure to extreme temperature fluctuations and corrosive particulates. The mine reported a 65% decrease in roller replacements and a 40% reduction in related labor and logistics costs. This successful deployment illustrates how Luoyang Jinlu’s self-fusing alloy powders, developed through years of R&D and certified under national standards, provide reliable, long-lasting protection for mining infrastructure—proving indispensable in harsh industrial environments.
--- Commitment to Quality and Innovation ---
• State-of-the-Art Testing Equipment:
Luoyang Jinlu Hard Alloy Tools Co., Ltd. maintains one of the most advanced quality control laboratories in China, equipped with state-of-the-art instruments including an inductively coupled plasma atomic emission spectrometer (ICP-AES/OES), a CS230 eco carbon-sulfur analyzer, a 0-300 oxygen-nitrogen analyzer, a laser particle size analyzer, and a scanning electron microscope (SEM). These tools enable real-time monitoring and precise analysis of raw materials and finished products throughout the entire production chain—from tungsten powder to cemented carbide and final mining tools. In a recent internal audit, the lab identified trace impurities in a batch of tungsten carbide powder that could have compromised tool performance. Thanks to the sensitivity of the ICP-AES system, the issue was detected before shipment, preventing potential field failures. This proactive approach ensures that every product meets or exceeds international quality benchmarks. Moreover, the SEM imaging capability allows engineers to analyze microstructural defects at the nanoscale, enabling continuous refinement of sintering parameters. Such rigorous testing not only safeguards customer trust but also reinforces Luoyang Jinlu’s reputation as a trusted partner in high-reliability industries like coal mining, where failure is not an option.
• Continuous Improvement in Production Processes:
Luoyang Jinlu’s commitment to innovation is reflected in its ongoing process optimization initiatives. Leveraging data collected from field deployments and lab testing, the company employs a closed-loop feedback system to refine its manufacturing techniques. For instance, after analyzing performance data from multiple coal mines, Luoyang Jinlu redesigned the heat treatment cycle for its carbide top hammers, increasing compressive strength by 18% while reducing brittleness. This improvement was validated through extensive simulation and field trials across three different mining sites. Similarly, the company adopted AI-driven predictive maintenance models in its production line, which reduced machine downtime by 25% and improved yield consistency. These advancements are supported by Luoyang Jinlu’s status as a National High-Tech Enterprise and its recognition as a “Specialized, Refined, and Innovative” Small Giant Enterprise by the Ministry of Industry and Information Technology. With over 700 employees dedicated to R&D and process engineering, the company continuously invests in training, digital transformation, and sustainable manufacturing practices. This relentless pursuit of excellence ensures that Luoyang Jinlu remains a global leader in providing next-generation mining tools that deliver unmatched reliability, efficiency, and value.
