The 17A explosion-proof belt scale has been successfully installed and commissioned at the coal washing plant

After coal is mined, it cannot be used directly and must undergo a washing process at the coal washing plant. To monitor coal washing production and analyze output, the coal washing plant needs to weigh raw materials and waste products.

Belt scales are widely used in coal washing plants, primarily for metering raw materials (raw coal), products (clean coal, middlings), and waste products (gangue, etc.), thereby providing quantitative analysis for detecting and controlling coal washing production.

The application of belt scales in coal washing plants varies depending on different materials and working environments, and the requirements for belt scales also differ.

In ordinary environments, conventional belt scales can be used. However, in some cases, especially for raw coal metering where coal dust and powder are abundant and the working environment is harsh, explosion-proof belt scales are required when applied at the coal outlet.

Recently, Guonuo Technology completed the installation and commissioning of the 17A explosion-proof belt scale at a coal washing plant. This was due to the harsh working conditions at the site, characterized by a large amount of coal dust and a long conveyor, necessitating a robust, adaptable, and explosion-proof belt scale.

The structural design of the Guonuo 17A explosion-proof belt scale meets the requirements of the coal washing plant's on-site environment and metering accuracy.

The 17A explosion-proof belt scale features a double-lever bridge structure, primarily formed by welding rectangular steel tubes, providing good rigidity, durability, and strong load-bearing capacity. The bridge structure reduces dust accumulation areas, preventing mechanical zero-point changes caused by dust.

Equipped with sensors and instruments housed in sealed explosion-proof enclosures, it effectively prevents dust ingress into internal components, is moisture-proof, rust-resistant, and has a certain degree of impact resistance.

Therefore, the Guonuo 17A explosion-proof belt scale can well adapt to the dusty and ash-laden environment of the coal washing plant.

The double-lever structure extends the effective weighing area of the belt scale. The bridge structure uses four-point support designed as trunnion supports, improving the linearity and sensitivity of the scale frame, while also providing advantages in resisting mechanical vibrations and belt misalignment, ensuring stable metering operations in the mechanical environment of the coal washing plant.

Additionally, the Guonuo 17A explosion-proof belt scale is equipped with highly sensitive and stable weighing sensors with functions such as lateral force resistance, low-temperature compensation, and overload protection. It also features a speed sensor with an Omron encoder core and double-wheeled rubber-coated rollers to real-time capture the speed of the upper belt's lower surface, ensuring accurate detection of belt speed.

The high-performance instrument is equipped with one-key zero calibration, online calibration, self-diagnosis, and automatic alarm functions. Each component of the 17A explosion-proof belt scale fully guarantees the metering accuracy requirements of the coal washing plant. After installation and commissioning by Guonuo's after-sales engineers, on-site practical applications confirmed stable and accurate metering precision.

The information technology functions of the Guonuo 17A explosion-proof belt scale meet the production monitoring and management needs of the coal washing plant. To achieve production monitoring and output analysis, the coal washing plant needs to obtain real-time belt scale metering data.

The Guonuo belt scale instrument has rich information interfaces that can be connected to the coal washing plant's network.

By configuring a belt scale upper computer system, managers can remotely view real-time data on raw coal/products/waste products, as well as historical data, providing data support for real-time production monitoring and output analysis. In addition to output data, equipment operation status is also shared, stored, and recorded in real-time.

After Guonuo's after-sales engineers completed the installation and commissioning of the 17A explosion-proof belt scale at the coal washing plant and put it into actual production application, observations confirmed stable metering accuracy, accurate and real-time production data from the instrument and remote belt scale system, and retrievable historical data, providing support and basis for the coal washing plant's production monitoring and analysis.
