Aeration system
Bulk powder storage silo has a cone mixing room in the center of bottom silo to reduce discharge pressure in silo and eliminate funnel flow. Mixing room is arranged 8 to 12 inlet holes. There is 8 to 12 aerating zones between mixing room and silo wall/shell. Aerate small circular zone in turn when discharging. Make some cement flow toward central mixing room. Mix them with gravity because of cutting horizontal layer during flowing from up to down. Homogenize then again because of continuous aerating and mixing room. The homogenized valve can meet 5 to 9 and power consumption is 0.15 KWh/t to 0.30 KWh/t.
