speed of conveyors in coal mining coal appliion and uses

Measuring level of coal on conveyors, silos and trains

The coal is carried up a lift and stocked in 2 buffer silos (18 m high). The two of them are half full with only one load from the lift. The level of the silo contents is regulated by a conveyor belt used for extracting the coal from below the storage silos and transporting it to a shuttle conveyor who leads the coal into the empty cells of 36 storage silos (20 m high).
