Belt conveyors are automated devices for transporting bulk materials in enterprises. They can transport materials from one location to another and are widely used in various industries such as mining, coal, building materials, and cement.
In actual production processes, merely transporting materials is insufficient. Enterprises need to control costs in raw materials and improve product quality in production. Therefore, it is necessary to know the weight of the materials.
So, during the transportation process of belt conveyors, enterprises need to weigh the transported materials. In the information age, to optimize production and improve production efficiency and quality, it is essential for enterprises to install scales on belt conveyors. These scales must be automated and informatized belt conveyor weighing devices.
Installing scales on belt conveyors is intended to optimize production and ultimately benefit enterprises. There are strict requirements for the weighing devices on belt conveyors.
Firstly, the transportation of materials by belt conveyors is continuous. Weighing during the stoppage of the conveyor cannot guarantee weighing efficiency. The scales installed on belt conveyors must ensure continuous and dynamic weighing.
Secondly, to improve production efficiency and quality, especially in trade settlement and production control scenarios, enterprises need precise knowledge of material weights. Therefore, the scales on belt conveyors must ensure weighing accuracy and stability.
Finally, with the development of informatization, enterprises are paying increasing attention to informatized management. The scales on belt conveyors must also meet informatization requirements and provide accurate, real-time, and historical measurement data for enterprise management.
So, how to achieve this? It can be realized by using a dynamic belt conveyor weighing device - a belt scale. There are various types of belt scales, mainly including electronic belt scales, nuclear belt scales, and laser belt scales. Among them, electronic belt scales have become widely used belt scales due to their unique advantages and are ideal belt conveyor weighing devices.
Nuclear belt scales are non-contact weighing devices that calculate the weight of the material being weighed based on the attenuation of gamma rays passing through the material.
Laser belt scales use lasers to scan the entire cross-section of the material passing on the belt to obtain the material's accumulation volume and then calculate the material weight based on its density.
Regarding their application limitations, nuclear belt scales have radioactivity, while laser belt scales have requirements for material density.
For materials with large variations in bulk density, accurate measurement cannot be achieved without configuring gamma ray density measurement. After understanding nuclear and laser belt scales, it becomes clear why they are not widely used.
Electronic belt scales differ in principle from the above two types of belt scales. They use a contact weighing method. When the weighing belt passes through the material, the weight of the material is detected by a weighing sensor and converted into a weight signal. The speed sensor detects the belt speed and converts it into a speed signal. The instrument receives and processes the weight and speed signals to calculate the instantaneous flow rate of the material and the cumulative flow rate over a certain period.
The working principle of the electronic belt scale shows that it has a simple structure, no restrictions on the volume and density of the transported material, and no environmental issues. Besides these advantages, the electronic belt scale has become an ideal device for belt conveyor weighing because it meets a series of requirements for installing scales on belt conveyors.
Firstly, the measurement of the electronic belt scale is continuous and dynamic, eliminating the need to stop the belt conveyor for weighing.
Secondly, with the development and application of technologies such as the Internet of Things and sensors, along with improvements in design concepts and structures, the measurement accuracy and stability of electronic belt scales are getting higher and higher. By selecting appropriate structures for different application needs, high-precision electronic belt scales can meet the requirements of high-precision applications such as trade settlement.
Finally, electronic belt scales are becoming more and more informatized and intelligent, providing enterprises with comprehensive data management support. Measurement data is transmitted and shared in real time, allowing remote supervision and operation by leaders.
When installing scales on belt conveyors, it is necessary to consider aspects such as measurement accuracy, stability, informatization management, operation and maintenance, as well as environmental protection and adaptability.
Electronic belt scales, with their simple structure and strong adaptability, can be customized according to user needs to achieve the desired accuracy and stability. They are ideal dynamic weighing devices for belt conveyors.
