The cement storage warehouse is equipped with a conical mixing chamber at the center of the bottom of the warehouse to reduce the unloading pressure inside the warehouse and eliminate funnel flow. The mixing chamber of the cement storage warehouse is equipped with 8-12 feeding holes, and there are 8-12 inflation zones in the annular area between the mixing chamber and the warehouse wall. During unloading, the wheel flows towards the opposite annular area for inflation, causing some cement to flow towards the central mixing chamber. In the top-down flow process, the horizontal material layer is cut to generate gravity mixing, and after entering the mixing chamber, it is further homogenized due to continuous inflation and stirring inside the mixing chamber. The average value of cement storage can reach 5-9. Electricity consumption is 0.15-0.30 kWh/t
