The load cells of concrete batching plants - From experience-based production to data-driven transformation

In recent years, with the improvement of quality standards for construction projects, the measurement accuracy and production efficiency of concrete batching plants have become the focus of attention in the industry. As a core production equipment, load cells, with advantages such as high precision, intelligence, and strong adaptability, are reshaping the concrete production model and injecting new impetus into the high-quality development of the industry.​

Traditional batching plants often suffer from substandard concrete strength due to measurement errors. The load cells used in the concrete mixing plant of Xinxing Construction Machinery Co., Ltd. have improved the measurement accuracy to ±0.1%, which far exceeds the dynamic measurement requirements of ±1% for materials such as cement and water specified in national standards. Through the linkage between the load cells and the PLC (Programmable Logic Controller) system, automatic raw material proportioning is realized. As a result, the mixing time of the production line is shortened by 25%, and the waste of raw materials is reduced by more than 15%.​

Intelligent upgrading is another core advantage of concrete batching plants. Load cells adopting 2.4G wireless communication technology can transmit real-time data to the ERP (Enterprise Resource Planning) management system. Managers can monitor key information such as silo weight and raw material consumption curves through computers in the monitoring room. The system is also equipped with an automatic alarm function for high and low material levels, which completely solves the problems of silo overflow and dust emission that frequently occur in traditional manual operations, and reduces equipment maintenance costs by more than 30%.​

The adaptability to harsh environments is a prominent highlight of the Xinxing load cells. Aiming at the characteristics of high dust and strong vibration in batching plants, the Xinxing load cells adopt a special protective design, which can withstand an impact of 5g acceleration and work stably in an environment ranging from -30℃ to 80℃. The design of installing them on the silo support structure avoids high-altitude operations, and installation and commissioning can be completed without stopping production, greatly reducing the difficulty of operation and maintenance.​

The application of load cells has promoted the transition of batching plants from experience-based production to data-driven operations, which not only ensures project quality but also helps the industry transform towards green and intelligent development. With the integration of the Internet of Things technology, load cells will play a more important role in concrete production and smart construction site development in the future.
