Coal feeders are specialized conveying equipment used in industrial production to continuously and stably transport coal (or other bulk materials) from storage equipment such as coal silos and hoppers to subsequent production equipment (such as boilers, crushers, coal mills, and belt conveyors) according to preset flow and uniformity requirements. They are the key link between coal storage and subsequent processing and combustion, precisely controlling the coal supply to ensure continuous and efficient production processes. They are widely used in industries that rely on coal as a fuel or raw material, including power generation, metallurgy, chemicals, building materials, and coal processing.
