Cement storage silo means establish a cone mixing chamber in the middle of silo bottom in order to reduce discharging pressure inside silo and remove funnel flow. There are 8-12 feeding holes inside cement storage silo and there are 8-12 aeration area between mixing chamber and wall of silo, which will cause air flow to make homogenization of cement, so the homogenization value is 5-9 while electrical consumption is 0.15-0.30kwh/t.
