Case Study | Guonuo Technology FSD Electronic Belt Scale Application in Iron Ore Mine

In modern mining production and sales operations, accurate material measurement is key to production supervision, cost control, efficient operation of production processes, and serves as an important basis for sales settlement.

With technological advancements, electronic belt scales, as precise and efficient online measurement devices, are increasingly widely used in various mining industries, including iron ore mines. Recently, Guonuo Technology's FSD Electronic Belt Scale has been successfully applied at Changyi Ludi Iron Mine, yielding significant benefits.

Changyi Ludi Iron Mine is a well-known enterprise in the local area engaged in iron ore mining, processing, and sales. The company places great emphasis on leveraging high technology to enhance production efficiency and refine management levels.

Its daily production relies on efficient transportation and accurate measurement, necessitating a high-precision, high-stability automated material measurement system to precisely control the entire production process. Faced with measurement challenges during ore transportation, the client, after multiple comparisons, ultimately selected Guonuo Technology's FSD Electronic Belt Scale as the solution.

Guonuo Technology's FSD Electronic Belt Scale is a highly flexible modular combination scale frame. Based on the site conditions, conveyor specifications, requirements, and budget at Changyi Ludi Iron Mine, a product solution consisting of two weighing idlers forming a unit module and equipped with four high-precision load cells was chosen.

The main site conditions and requirements were as follows: belt speed of 1.7 m/s, idler spacing of 1000 mm, belt width of 800 mm, belt length of 31 m, rated flow rate of 0-200 t/h, and a requirement for measurement error not exceeding 0.5%.

Based on the above conditions, the iron ore transportation volume was moderate, and the belt length was not suitable for a dual-lever structure with a complex scale frame and long weighing area.

Guonuo Technology's FSD-M1 Belt Scale met both the site conditions and budget and accuracy requirements. Multiple on-site physical calibrations also proved its measurement performance:

In the first calibration, the zero value was 1.76, the instrument displayed value was 3.52, the calibration value was 3.64, with an error of 0.032, and a calibration coefficient of 0.85238; in the second calibration, the zero value was 1.76, the instrument displayed value was 4.18, the calibration value was 4.2, with an error of 0.0047, and a calibration coefficient of 0.88396; in the third calibration, the zero value was 1.76, the instrument displayed value was 4.3, the calibration value was 4.29, with an error of 0.0023, and a calibration coefficient of 0.87766.

Besides being influenced by the product's inherent quality and technical performance, the measurement performance of an electronic belt scale is also significantly affected by its installation and commissioning, which are crucial measures to ensure subsequent application effectiveness.

After thoroughly understanding the site conditions, Guonuo Technology's after-sales engineers promptly formulated a detailed installation and commissioning plan. Following installation, six physical calibrations were conducted, with the errors in the last four calibrations all being less than 0.5%, earning recognition from the site.

After the hardware installation was completed, the after-sales engineers proceeded with the commissioning of the industrial computer belt scale measurement software system.

Given that the on-site industrial computer system was outdated, Guonuo Technology's engineers assisted in upgrading the system and completed the industrial computer software commissioning. Tests confirmed that measurement data and belt scale operation data were displayed in real-time, with historical data accessible and exportable.

Leaders at Changyi Ludi Iron Mine expressed that the data functionality was highly beneficial for transparent and comprehensive supervision of the production process.

By introducing Guonuo Technology's FSD Electronic Belt Scale, Changyi Ludi Iron Mine has achieved significant benefits, successfully resolving previous measurement issues characterized by low accuracy, inefficiency, management difficulties, and data lag. The application of Guonuo Technology's FSD Belt Scale has notably improved the measurement accuracy of iron ore, aiding in optimization of management and enhancing refined production and management levels.
