Engineering Case Study: Installation and Application of Automatic Coal Sampling Machine on Coal Conveyor Belts at Jieneng New Energy

Currently, many thermal and power companies still rely on manual sampling for incoming coal, which is time-consuming, labor-intensive, less accurate, costly, and difficult to supervise, making it unable to meet the demands of modern production.

In contrast, mechanical sampling under automatic control is time-saving, labor-efficient, and highly accurate, widely applied in coal mines, thermal power plants, electric utilities, coal washing plants, and other settings. The application of automatic coal sampling machines on coal conveyor belts has become an inevitable trend.

Lianyungang Jieneng New Energy Co., Ltd. is a modern thermal and power enterprise where precise sampling and testing of incoming coal directly relate to its production efficiency and economic benefits. To enhance the automation level and representativeness of coal quality testing, Jieneng New Energy introduced an automatic coal sampling machine on coal conveyor belts from Guonuo Technology.

The practical application has verified that the automatic sampling machine not only optimizes the coal quality testing process but also strengthens the company's overall production management capabilities and economic benefits.

Pre-sales Technical Solution Formulation

At the project's inception, Guonuo Technology conducted an on-site visit to Jieneng New Energy to thoroughly understand the operational status of its coal conveyor system, sampling requirements, and existing technical bottlenecks.

Based on the actual situation and Jieneng New Energy's specific needs, Guonuo Technology tailored a technical solution for the automatic coal sampling machine on coal conveyor belts. The solution covered hardware configuration, sampling strategy design, and took full account of compatibility with existing systems and ease of later operation and maintenance, ensuring the solution was both advanced and practical.

Strict Manufacturing Process Supervision

To ensure the quality of the automatic sampling machine, Guonuo Technology strictly manufactured and supervised the process according to the finalized design drawings. From raw material procurement, production processing to final product inspection, each step adhered to high-standard quality control procedures.

Particularly for key components of the sampling machine, such as the sampler and divider, precision machining ensured stable performance and strong durability. Additionally, the sampling machine underwent rigorous factory testing before shipment to ensure it met both Jieneng New Energy's requirements and industry standards.

Real-time Feedback During Installation

During the installation phase, Guonuo Technology dispatched experienced after-sales engineers to Jieneng New Energy's site for equipment installation and commissioning. The engineers strictly followed the established plan, recording various data and providing real-time feedback on the installation progress. 

Simultaneously, they maintained close communication with Jieneng New Energy's on-site supervisors, promptly reporting progress and addressing any issues encountered, ensuring the smooth progress of the installation work.

For example, according to the design drawings, the first conveyor pipe of the sampling head was supposed to fall vertically, but due to an obstruction from a steel beam on-site, the sampling head and collection box were modified to resolve the issue while ensuring on-site safety and application requirements.

Practical Application Effect Evaluation

After the installation of the automatic coal sampling machine on the coal conveyor belt was completed, it entered a trial operation phase. Jieneng New Energy organized dedicated personnel to conduct a comprehensive evaluation of the sampling machine's performance and application effects, including sampling accuracy, work efficiency, stability, and failure rate.

After a period of continuous operation, the results showed that the sampling machine significantly improved sampling accuracy and efficiently completed sampling tasks without manual intervention. Additionally, the automatic recording and display of sampling data facilitated real-time sampling site supervision and subsequent data management and analysis.

Through this engineering case study, the successful application of Guonuo Technology's automatic coal sampling machine on coal conveyor belts at Jieneng New Energy demonstrates its advantages in enhancing coal quality testing efficiency and accuracy. Guonuo Technology provided robust technical support to Jieneng New Energy with its advanced technical solutions, strict manufacturing processes, and efficient installation services.
