Double Inlet and Double Outlet Coal Mill 

In the double-input and double-output coal mill system, raw coal enters the coal drop pipe through the coal feeder with automatic speed control, falls under the conveying device by gravity, and is fed into the cylinder of the coal mill by the rotating winch cage, where it rotates. A certain amount of steel balls are installed in the cylinder to grind raw coal into pulverized coal. The hot primary air enters the cylinder of the mill from the hollow tubes on both sides of the coal mill, dries the raw coal and pulverized coal, and lifts the ground pulverized coal through the circular channel of the grinding cage to feed the coal into the mill. In the separator above the machine, unqualified pulverized coal is returned to the cylinder for re-grinding, and qualified fine powder is sent to the burner of the boiler. The coal mill can easily achieve high-level automatic control; this product has good raw coal pre-drying performance and low-temperature hot air powder conveying function, and t…
