Recently, Luoyang Jinlu Cemented Carbide Tools Co., Ltd. (hereinafter referred to as “Luoyang Jinlu”) completed an on-site comparative test of its cladded wear‑resistant plates (CCO PLATE) at a major molybdenum mining company in Henan Province. The test results show that Luoyang Jinlu’s 10+6 cladded wear‑resistant plates, when used under the operating conditions of a vibrating ore‑discharge machine in hard‑rock molybdenum mines (F14–F16), achieve a service life of 5–6 months—2.5 to 3 times that of comparable products, which typically last about 2 months. This delivers outstanding overall cost‑effectiveness, enabling customers to significantly reduce costs and improve efficiency.

01 Test Background and Operating Condition Comparison

This test was conducted on the Henan Weimeng Vibratory Ore‑Discharge Machine (model 3600×1500), which operates continuously for 24 hours per day, processing up to 23,000 tonnes of ore daily. The ore exhibits a hardness as high as F14–F16, representing extremely severe operating conditions characterized by high abrasion and high impact. The test compared Luoyang Jinlu’s products with wear‑resistant plates from other brands, with the following specific parameters:

02 Significant advantages in service life and wear resistance

The initial thickness of the Luoyang Jinlu hardfacing wear‑resistant plate was 16 mm. After 3–4 months of service, a routine inspection revealed a remaining thickness of 12 mm, with only 4 mm of material worn away. Ultimately, the product achieved an actual service life of 5–6 months, whereas previously used wear‑resistant plates from other brands lasted only about 2 months. With unit procurement costs remaining roughly comparable, Luoyang Jinlu’s wear‑resistant plates, thanks to their extended service life and reduced replacement frequency, lower overall purchasing expenditures, helping customers cut costs and boost efficiency.

03 Maintenance frequency has been significantly reduced, and production capacity has improved markedly.

The group is responsible for the equipment operation and maintenance management of more than ten mines. Under the previous maintenance regime, equipment inspections and repairs were carried out every month. After adopting Luoyang Jinlu wear‑resistant plates, the interval between major overhauls has been extended from one month to five months, reducing the annual number of overhaul cycles from 12 to just 2–3—a decrease of over 75%. Each overhaul now takes an average of one day, and the resulting reduction in downtime translates into an additional annual processing capacity of approximately 70,000 tonnes of ore. Moreover, each overhaul can be completed with only one or two workers, significantly easing labor intensity and lowering operational safety risks.

04 Outstanding Overall Operational Performance

Thanks to its outstanding performance, Luoyang Jinlu wear‑resistant plates offer a longer service life, effectively reducing operating costs for customers. According to customer feedback, if widely adopted across the Group’s mining operations, these plates can significantly streamline mine‑site maintenance and operations, minimize unplanned downtime, enhance overall equipment utilization, and consistently deliver strong economic benefits to the mining enterprise.

Luoyang Jinlu continues to deepen its expertise in demanding applications such as mining and construction machinery, committed to delivering high‑quality wear‑resistant solutions. The recent field tests yielded outstanding results, further validating the exceptional technical advantages and robust reliability of its wear‑resistant plates under hard‑rock, highly abrasive conditions.
