When the material layer is too thin, the feeding amount should be increased to increase the equipment pressure difference, stabilize the material layer, and reduce equipment vibration. If the material layer is too thick, you should immediately reduce the amount of feed and increase the amount of ventilation to ensure a smooth discharge system.
