The Macheng Iron Mine is located in Macheng Town, Luannan County, Tangshan City, Hebei Province, situated on the resource-rich eastern Hebei Plain. The mining area covers 10.08 square kilometers, with proven reserves of 995 million tons, making it one of the largest deep‑shaft iron mines in China.

The Macheng Iron Mine produces 7 million tons of iron concentrate annually, and the Macheng iron‑concentrate pipeline project is currently the largest in China in terms of throughput.
At 13:28 on July 13, the Dashihe Terminal Valve Station successfully discharged the concentrate slurry, marking the first successful full‑process heavy‑load commissioning of the Macheng Iron Mine’s beneficiation system.
Dashihe Terminal Pump Station
This trial run involves the coordinated operation of 550 sets of equipment across 10 process stages at the Macheng Beneficiation System and the Dashih River Terminal Station, a scale and level of complexity that are both rare in the industry.
To ensure the successful completion of the full‑process heavy‑load commissioning on the first attempt, Macheng Mining conducted advance planning and meticulous scheduling, developing a coordinated heavy‑load commissioning plan that clearly defines responsibility zones, specific tasks, accountable personnel, and deadlines. In light of the new equipment and processes being deployed for the first time in the ore‑processing flow, the company thoroughly explored technical parameters and operational patterns, streamlined the production process, and established a robust data foundation to support ongoing operations.
Pulaisen’s ultrasonic flowmeter and non‑nuclear impact‑type density meter, a highly popular clamp‑on combination in the mining industry, have been engaged in technical coordination and dialogue with the design institute and the client since the very outset of the Macheng Concentrate Conveyance Project. It is an honor that the Macheng Ore‑Processing and Concentrate Conveyance Project ultimately selected Pulaisen Instruments’ clamp‑on flow‑and‑density solution.
The sonar flowmeter and the non‑nuclear impact‑type density meter are installed at the Macheng Concentrate Pump Station and at the Dashih River terminal pump house, respectively, after a 68.5‑km transmission line. The readings from the sonar flowmeters at both ends are consistent, and preliminary sampling and commissioning of the non‑nuclear density meter have been completed.

The full-process heavy-load commissioning of the Macheng Iron Mine’s beneficiation system was successfully completed on the first attempt, marking a significant milestone in the development of an intelligent mine at Macheng and serving as further evidence of customer recognition for Pulsar’s online smart instruments, including sonar flow meters and non‑nuclear density gauges, in the mining sector. Looking ahead, Pulsar will continue to strengthen its core business, remain customer‑centric, and drive continuous innovation to deliver even higher‑quality, more competitive products and services.
