The design of belt and apron feeders at a coal mine

  • ApronSeal Single Skirting- Belt Sealing

    At a generating plant, 5000 tons per day of PRB coal are metered via belt feeder onto conveyors and into the plant's ten bunkers. With surge of material as railcars unload, combined with the high head pressure from the hoppers, the belt feeders suffered extensive spillage. This spillage was compounded by the worn-out condition of the chutes.
