Jinlu Cement Cutter Head – An Essential Tool for Milling and Scarifying Concrete Pavements

As China’s demand for road infrastructure maintenance continues to grow, projects such as the reconstruction and expansion of rural cement pavements and internal roads within industrial parks are becoming increasingly common. Consequently, the market is placing ever-higher demands on the efficiency, precision, and cost-effectiveness of cement pavement milling. Traditional milling cutters often encounter significant challenges—rapid wear, frequent replacement, and substantial overall cutting resistance—when processing high‑hardness cement concrete pavements of C30 grade or higher.

Luoyang Jinlu PDC Centerless Drill Bit: Solving the Challenge of Drilling Efficiency in Medium-Hard Rock Formations

In geotechnical engineering operations, the efficiency and cost of drilling directly impact the progress of the entire project. Particularly in medium‑hard rock formations, conventional drill bits often suffer from slow penetration rates and short service lives. To address these challenges, Luoyang Jinlu has introduced its PDC coreless drill bit, which, thanks to a suite of proprietary technological advantages, has become an ideal solution for enhancing the overall performance of drilling operations.

Luoyang Jinlu hardfacing wear-resistant plates extend the service life of vibratory ore-discharging machines by several times.

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

Advantages and Applications of Post‑Processing Techniques for Alloy Column Tooth Surfaces

I. During drilling in highly hard (rock hardness coefficient F14–16) and highly abrasive formations, the carbide teeth of down-the-hole drill bits are subjected to intense impact and cutting‑friction against the tough rock. Conventional manufacturing processes often result in carbide teeth with poor surface stress states, insufficient surface densification, and reduced toughness. Under sustained loading, microcracks propagate rapidly, leading to premature failure modes such as tooth chipping, fracture, and excessive wear, ultimately rendering the drill bit unusable. Frequent replacement of drill bits not only significantly increases mining consumables costs but also severely disrupts continuous production operations.

Introduction and Applications of Tunneling Drill Rods

Rock‑drilling tools include drill bits, drill rods, and drill shanks, and are used to bore blast holes in rock. The drill rod serves as the link between the drill shank and the drill bit, transmitting the impact energy and rotational torque required for rock drilling.

As solid as a shield, operating with peak efficiency: A “hardcore” solution for repairing the roll surfaces of high-pressure roller mills.

In the fields of bulk material comminution and mineral processing, the high-pressure grinding roll (HPGR) is undoubtedly the “heart” of enhancing material‑crushing efficiency. However, when dealing with highly hard, strongly abrasive ores, the severe wear of the roll‑face liners has long been a persistent technical challenge for major mining companies. Frequent shutdowns for maintenance not only erode production profitability but also drive up operating costs.

Jinlu Asphalt Multi‑Purpose Cutter – A Must‑Have Tool for Asphalt Road Repair

As China’s demand for road infrastructure maintenance continues to grow, urban road reconstruction, highway upkeep, and pavement cold recycling are placing increasingly stringent requirements on the efficiency, precision, and cost-effectiveness of milling operations. When dealing with high‑hardness asphalt mixtures and complex working conditions, operators often encounter challenges such as rapid tool wear and frequent component replacements.

Golden Years, New Beginnings: The 2026 Reserve Cadre Specialized Training Program Concludes Successfully

To help the 2026 cohort of newly recruited reserve cadres swiftly transition into their roles and integrate into the company’s development rhythm, while strengthening the organization’s pipeline of young talent, Luoyang Jinlu held a two-week specialized training program for the 2026 reserve cadre class from July 6 to 17. The program empowered these new young employees by solidifying their theoretical foundations, enhancing their professional competencies, and aligning them with clear career‑development pathways.

Pragmatic Action Fuels Growth; Steadfast Execution Ushers in a New Chapter — The 2025 Reserve Cadre Annual Defense Conference Concludes Successfully

On the morning of July 18, Luoyang Jinlu successfully held and concluded its annual defense session for the 2025 cohort of reserve cadres. The event provided a comprehensive assessment of the reserve cadres’ achievements over their first year of on-the-job rotations and frontline experience. Ten reserve cadres took to the stage one by one to present their performance reports, while members of the company’s Executive Committee and other relevant leaders attended in person, jointly witnessing the growth and transformation of these young talents.
