The system usually includes components such as conveyor belts, belt scales, metal detectors, sampling systems, and monitoring software connected to them. These components work together to ensure that the coal transportation process is both efficient and meets environmental and safety standards. System components and functions: Conveyor belt: used to physically move coal, belt scale: used to measure the amount of coal passing through the conveyor belt to ensure the balance between supply and demand, metal detector: detect metal impurities that may be entrained in the coal during transportation, sampling system: regularly extract coal samples to detect their quality and calorific value, monitoring software: real-time monitoring of the status of all the above equipment, and provide alarm, data recording and reporting functions.
