Chongqing Hengbiao - Industry-leading Technological Breakthrough: Hengbiao's Weighing-Linked Intelligent Sprinkler System Upgrade Project Successfully Delivered and Put into Use   Recently, a fully automatic conveyor belt weighing and dust suppression system independently developed and implemented by Chongqing Hengbiao Technology was successfully completed and delivered. After 15 days of on-site installation and commissioning, the system was officially put into use, with results far exceeding customer expectations. This intelligent dust suppression solution, developed based on weighing and control technology, is a first in the sand and gravel aggregate industry, marking a new milestone for Hengbiao in the field of intelligent environmental dust control and providing a new implementation model for the spraying transformation of domestic mines and sand and gravel aggregate production lines. It is understood that the original self-managed spraying system by the client had significant drawbacks: relying on their own experience, the client created their own spraying device by drilling holes in the conveyor pipeline, lacking water control and start/stop management design. The water output was uncontrollable, with frequent large-scale water spraying eroding the production equipment, causing multiple mechanical failures, resulting in significant water waste and disrupting continuous production line operation. The client's actual production needs were clear: the system should automatically activate dust suppression when the conveyor belt is carrying materials, and immediately stop operating and shut down when the system is empty, completely eliminating the traditional manual start/stop mode. Leveraging Hengbiao's years of experience in weighing measurement and control, and automated control systems, along with extensive project implementation experience, the client proactively contacted Hengbiao's manager, Li Pinhua, to propose a customized intelligent sprinkler system upgrade. Upon receiving the project requirements, Hengbiao quickly organized a special seminar with its R&D and technical departments. Taking into account the layout of the six conveyor belts on-site, the dust generation patterns, and the existing pipeline conditions, they finalized the overall design scheme for the weighing sensor-linked spray system. The entire system uses Hengbiao's mature weighing detection module as its core hardware. Each of the six conveyor belts is independently equipped with a weight acquisition unit. Once a weight signal is generated when material passes over any belt, the data is instantly transmitted back to the central control system. This triggers solenoid valves to precisely control the start and stop of the water supply pipeline and spray nozzles, achieving fully automatic closed-loop operation with spraying upon material arrival and stopping when no material is available, requiring no manual operation throughout the process. In addition, the system is equipped with a liquid level monitoring module, which can automatically identify water tank shortages and full conditions in real time. It automatically stops the pump when water is low and automatically shuts off the water supply when full, preventing overflow and dry-burning failures from the source, thus achieving the dual advantages of water conservation and equipment protection. After the project commenced, Hengbiao's technical installation team meticulously planned the construction schedule and completed the entire process of equipment wiring, sensor installation, pipeline modification, and central control system debugging in just 15 days. Since its commissioning, the system has precisely solved many historical problems, such as damaged equipment from the original large-scale water spraying system, ineffective water consumption, and cumbersome manual management. The dust reduction effect has been stable and up to standard, and water resource consumption has been greatly reduced, earning full recognition and high praise from customers. Hengbiao has consistently focused on the R&D and manufacturing of industrial weighing equipment and automated control systems, continuously innovating to address the pain points of environmental upgrades in the mining, sand and gravel, and building material aggregate industries. The successful implementation of this industry-first weighing-linked intelligent spraying project marks Hengbiao's formal expansion from a weighing equipment manufacturer to a provider of comprehensive intelligent environmental dust control solutions. Moving forward, Hengbiao will leverage the technological achievements of this project to continuously optimize and iterate its spraying control products, promoting intelligent spraying dust suppression upgrades to major mines and sand and gravel aggregate plants nationwide, and using its core automation technology to steadily advance the construction of green mines.

First, for loading and unloading weighing in ports, docks, and highway transportation. These bulk materials need to be loaded by Truck Scales. To ensure that the tonnage is not exceeded or under-tonnaged, users need to install electronic scales on the Truck Scales to meet this requirement. Second, for train overload restrictions, such as railway freight stations (bulk materials): for example, bulk materials such as coal, ore, and mineral powder transported by train. Third, for batching: the batching scope of Steel Foundation Truck Scales electronic scales is quite broad, covering various fields of industrial and agricultural production. If users do not want to invest a large amount of capital and space to install a weighbridge, such as for the sale of sand and gravel on highways, they can also directly use this scale for weighing and selling. Weighbridge (vehicle scale). It is used to weigh the goods loaded in a vehicle. You can weigh the vehicle first, or the empty vehicle, but you must weigh it twice. That is, if you weigh the vehicle first, you must weigh the empty vehicle again after the goods are unloaded. This allows you to calculate the weight of the goods in the vehicle.

After installation, the Electronic Belt Scales needs to be adjusted for overall accuracy, which is the most difficult step in the installation process. Below is a detailed explanation. After installing an Electronic Belt Scales, first perform a simulated calibration. This involves randomly scooping up and shaking a load to calibrate it. Don't worry about the exact accuracy; just get a rough estimate. Observe whether the Electronic Belt Scales is working properly. Then, adjust the throttle compensation. Lift the scooter several times with high throttle, then several times with low throttle, and see if they are the same. If not, adjust it using speed compensation to make them the same. Next, perform single-bucket calibration. Use a weighbridge for comparison to adjust the Electronic Belt Scales to match the electronic weighbridge. The final step is to perform a full-vehicle calibration by loading three or four loads and observing the error. Then, perform a full-vehicle calibration. After these adjustments, the accuracy should be basically satisfactory. If the customer is not loading loads but using the Electronic Belt Scales for material handling, then full-vehicle calibration is not necessary.

Recently, Chongqing Hengbiao Technology Co., Ltd. (hereinafter referred to as "Hengbiao Technology") successfully delivered an intelligent automatic sprinkler dust suppression system based on weighing detection, which was applied to the dust suppression operations of six material conveyor belts of a large building materials company. This company had previously experienced equipment damage due to excessive water flow in its self-installed sprinkler pipes, and was unable to achieve on-demand spraying. Leveraging its deep expertise in weighing equipment, Hengbiao Technology, in conjunction with its R&D and technical departments, quickly tackled the challenges and customized a fully automated sprinkler solution that enables unmanned operation and precise linkage of material conveying. After 15 days of on-site installation and commissioning, the project received unanimous praise from the client, marking a milestone breakthrough for Hengbiao Technology in environmental intelligent transformation. According to Li Pinhua, the project manager at Hengbiao Technology, the client had previously laid sprinkler pipes based on their experience and drilled a row of small holes in the pipes for dust suppression. However, due to the continuous spraying of water and the difficulty in controlling the water volume, large amounts of water were directly sprayed onto the machinery, causing multiple malfunctions of critical components such as motors and bearings. At the same time, the client clearly stated their core requirement: the sprinkler system should only be activated when there is material passing over the conveyor belt; if there is no material (no weight) on the conveyor belt, the sprinkler system must be stopped immediately to avoid wasting water resources and corroding the unloaded equipment. However, traditional manual start/stop methods are slow to respond and prone to misoperation, failing to meet this precise control requirement. As a technology-driven company with a long history of expertise in weighing equipment, Hengbiao Technology quickly identified the technological convergence points behind the pain points. "The customer proactively approached us because they valued Hengbiao's mature experience in weighing sensing and material detection," Li Pinhua recalled. Upon receiving the request, Hengbiao Technology immediately organized joint discussions between its R&D and technical departments, ultimately finalizing an automatic spraying system model that deeply couples weighing signals with the spraying actuator. Based on the customer's actual layout of 6 conveyor belts, Hengbiao Technology installed a high-precision weighing detection device on each conveyor belt to sense the weight of the material on the belt surface in real time. The system logic is designed as follows: when any conveyor belt detects material (weight exceeding the set threshold) passing by, it immediately sends a digital signal to the control room PLC. The control room automatically opens the solenoid valve of the corresponding conveyor belt, connects the water circuit, and starts the spray head in that area to suppress dust. Once the material on that conveyor belt has been transported and the weight has returned to zero, the system immediately closes the solenoid valve and stops spraying. The entire process is fully automated, requiring no manual intervention. Simultaneously, the system integrates a water level sensor module that automatically detects whether the water tank is "full" or "short," sending alerts or interlocking protection signals to the host computer to ensure the continuous and stable operation of the sprinkler system. Compared to the previous extensive approach of "all water on, flooding the system," the new system achieves on-demand water supply with precise targeting, eliminating the potential for excessive water to damage the equipment. “This system is even better than we expected—it truly achieves spraying only when there is material and stopping when there is no material, and each conveyor belt is independently controlled, saving water and protecting the equipment,” said the customer's on-site manager. Manager Li Pinhua revealed that after industry research and comparison, this “weighing-linked spraying” mode has not yet been seen in similar applications, making it an industry first developed entirely independently by Hengbiao Technology.   The successful delivery of this project not only marks a significant step for Hengbiao Technology from a single weighing equipment supplier to a comprehensive “weighing + intelligent control” solution provider, but also provides a replicable, low-cost dust suppression transformation model for dust-generating scenarios such as mines and aggregate plants. Li Pinhua stated, “We will continue to iterate this system and promote it to more industrial sites that require on-demand spraying, contributing to the construction of green mines and smart factories.”

In the production of sand and gravel aggregates, the material conveying process involves complex operating conditions and diverse conveying equipment specifications. Achieving high-precision and highly adaptable continuous weighing has always been a pain point for industry users. Recently, three double-scale belt scales from Chongqing Hengbiao Technology Co., Ltd. (hereinafter referred to as "Hengbiao Technology") were successfully installed and deployed in a large sand and gravel plant project in Kunming. These scales cover three mainstream belt width specifications: 800mm, 1 meter, and 1.2 meters, perfectly addressing the complex conveying scenario with a customized solution, once again validating Hengbiao Technology's core strength in "making weighing simpler." This sand and gravel plant has long material conveying lines and numerous transfer points, with different sections equipped with conveying equipment of 800mm, 1 meter, and 1.2 meter widths. Traditional belt scales often use "universal models" to handle different widths, resulting in low installation compatibility and poor weighing stability. Especially under conditions of high impact from falling sand and gravel and frequent fluctuations in belt tension, measurement accuracy is difficult to guarantee. The customer had previously purchased weighing equipment from Hengbiao Technology multiple times and highly recognized the product quality and service responsiveness. Faced with this upgrade and renovation requirement, the customer once again chose Hengbiao Technology and put forward clear requirements: the belt scale must be tailored to different conveyor bandwidths to ensure that each belt scale is perfectly matched with the on-site conveyor structure, idler spacing and installation space, while meeting the requirements for long-term stable operation in heavy sand and gravel load and high humidity environment. Hengbiao Technology's technical team conducted an in-depth on-site survey, meticulously verifying the bandwidth, trough angle, idler roller type, and installation position parameters of the three conveyor lines. They then custom-designed three dual-frame belt scales:   Multiple Specifications: Adaptable to 800mm, 1m, and 1.2m bandwidths, with zero installation dimensional error; Dual-Frame Structure: Employing two independent frames working collaboratively, effectively distributing the impact force of sand and gravel materials, resulting in stronger load-bearing capacity and significantly improved resistance to lateral forces and off-center loads; High-Precision Sensors and Intelligent Instruments: Real-time acquisition of weight and speed signals, using dynamic compensation algorithms to eliminate the impact of belt tension variations and idler roller friction on measurement accuracy.   The dual-frame design is particularly suitable for materials like sand and gravel, which are lumpy, granular mixtures with large instantaneous flow fluctuations. It ensures no deformation under long-term overload while maintaining industry-leading dynamic measurement errors.   Hengbiao Technology dispatched an experienced engineering team to the site for construction, strictly adhering to installation specifications and completing each step, including scale frame positioning, sensor leveling, speed sensor alignment, and instrument parameter calibration. In response to the dusty environment of the sand and gravel plant, the key electrical interfaces were also sealed and reinforced.   After installation, the team conducted repeated comparisons and calibrations using actual materials to ensure that the output data of the three belt scales was consistent and stable under material loading conditions. From arrival to delivery, the equipment was put into daily production smoothly within just a few days, without causing any delays to the client's normal operations.   The successful delivery of the Kunming sand and gravel plant project once again demonstrates Hengbiao Technology's core capabilities in "non-standard customization and precise adaptation" in the field of dynamic weighing of bulk materials. No matter how complex the conveying conditions or how diverse the specifications, Hengbiao Technology consistently helps users achieve efficient, accurate, and stable production metering through deeply customized products and full-process technical services.
