Fly ash is one industry powder type. To storage fly ash needs to avoid wet air. Spiral steel silo is the best steel structure for fly ash storage. Bidragon spiral silo adopts imported LIPP technology from Germany. All of our steel silo are in round shape with diameter from 3 meters to 30 meter per silo.
Bidragon fly ash silo includes hopper bottom steel silo and flat bottom steel silo. The conical hopper bottom silo capacity always be small and not more than 2000 ton. Each fly ash silo will be equipped with some accessory equipment, such as vibrator on silo hopper, aeration box on silo hopper, in order to ensure the fly ash discharge smoothly. The flat bottom silo always has invert cone inside steel silo bottom, whose function is to reduce the pressure when discharging fly ash from the center of steel silo top. For this type, the invert cone can avoid the fly ash flowing down to the aeration box directly. Here, the aeration box is used to make the fly ash discharge smoothly. During the flat bottom silo for fly ash storage, sometimes we will design several invert cones inside silo bottom.
Bidragon ash silo structure includes steel structure and concrete foundation structure. Steel structure foundation silo is always be small and this small silo capacity is less than 1500 ton, while the concrete structure foundation silo generally big and silo capacity is more than 1500ton.
