Aiming at the problem of serious shutdowns of conveyors caused by abnormal coal flow of scraper conveyors, a coal flow monitoring method based on speckle structured light is proposed. The point cloud data of the coal body on the scraper conveyor is collected through the speckle structured light acquisition system. Then, the proposed PDSAlgorithm (Planar Density Simplification Algorithm) is ...

A minimum airtocoal weight ratio of :1 is desired at full load. The ratio could be higher at lower loads (more air per pound of coal). Failure to provide adequate airflow through the mill can result in spillage of coal. The exhauster discharge pressure is an indicator of flow and velocity through the coal piping.
