Discharging, the compressed air from the tank into the bottom of the tank, the permeability of the cement layer of fluidization device into the small streams, filling evenly into the cement, the formation of air - the cement mixture in the container under the action of pressure difference inside and outside the cement that is along the discharge tube escape. Pneumatic discharging discharging method is fast, dusty little long flexible discharge tube can be used to discharge any of the advantages of height and distance, and rain days in the open operation.
