The 17A explosion-proof belt scale has been successfully installed and commissioned at a coal washery, and its post-use production output has been verified as accurate!

Coal cannot be used directly after mining and must undergo the washing process at a coal washery. To monitor coal washing production and analyze output, the coal washery needs to weigh raw materials and waste.

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

The application of belt scales in coal washeries varies depending on the material and working environment. In normal environments, conventional belt scales can be used.

However, in certain situations, such as metering raw coal where coal powder and dust are prevalent and the environment is harsh, explosion-proof belt scales are required for use at the coal inlet.

Recently, Guonuo Technology completed the installation and commissioning of a 17A explosion-proof belt scale at a coal washery. Due to the high volume of coal dust and dusty conditions at the site, along with the long conveyor and the need for a robust, adaptable, and explosion-proof belt scale, the 17A model was chosen.

The structural design of the Guonuo 17A explosion-proof belt scale meets the on-site environmental and metering accuracy requirements of the coal washery.

The 17A explosion-proof belt scale features a double-lever bridge structure, with the main body welded from rectangular steel pipes, providing good rigidity, durability, and strong load-bearing capacity.

The bridge structure has a minimal dust accumulation area, preventing mechanical zero-point changes caused by dust. The equipped sensors and instruments have sealed explosion-proof enclosures, effectively preventing dust ingress into internal components, and are moisture-proof, rust-proof, and resistant to impact.

Therefore, the Guonuo 17A explosion-proof belt scale can well adapt to the dusty environment of the coal washery. The double-lever structure extends the effective weighing area of the belt scale, and the bridge uses a four-point ear-axis support design, improving the linearity and sensitivity of the scale frame, while also providing advantages in resisting mechanical vibration and belt misalignment, ensuring stable metering operations in the mechanical environment of the coal washery.

Additionally, the Guonuo 17A explosion-proof belt scale is equipped with highly sensitive and stable weighing sensors, featuring functions such as lateral force resistance, low-temperature compensation, and overload protection.

It uses an Omron encoder core speed sensor with a double-wheel rubber-coated design roller to real-time collect the speed of the upper belt's lower surface, ensuring accurate belt speed detection. The high-performance instrument offers one-key zero calibration, online calibration, self-diagnosis, and automatic alarm functions.

Each component of the 17A explosion-proof belt scale fully meets the metering accuracy requirements of the coal washery. After installation and commissioning by Guonuo's after-sales engineers, on-site application confirmed accurate and stable metering precision.

The information functionality of the Guonuo 17A explosion-proof belt scale meets the production monitoring and management needs of the coal washery.

To achieve production monitoring and output analysis, the coal washery requires real-time belt scale metering data. The Guonuo belt scale instrument features rich information interfaces, allowing it to be connected to the coal washery's network.

By configuring a belt scale upper computer system, managers can remotely view real-time and historical data of raw coal/products/waste through their computers, 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 the installation and commissioning of the 17A explosion-proof belt scale by Guonuo's after-sales engineers, it was put into actual production application. Observations confirmed stable metering accuracy, accurate real-time and historical data from the instrument and remote belt scale system, providing support for production monitoring and analysis at the coal washery.
