coal dust buffer tank with transport system to the mill; As part of the work carried out, the conveyor belt supplying coal dust from the coal hall to the coal dust tank was partially covered and the transfer of coal dust was reinforced. This enabled the installation of an explosion decoupling system by means of HRD cylinders on the hopper.
Central cross belt sampler is used to the coal moving stream which is installed on the coal conveyor belt. The working principle of central cross belt sampler is sampler rotates along the axis of the center line of the conveyor belt. The primary sampler size must more than 30mm. Stationary sampling method
Monitoring and diagnosis of coal mill systems are critical to the security operation of power plants. The traditional datadriven fault diagnosis methods often result in low fault recognition rate or even misjudgment due to the imbalance between fault data samples and normal data samples. In order to obtain massive fault sample data effectively, based on the analysis of primary air system ...
