Because the cone hopper type cylindrical bin adopts a self-flow discharging mode, the cone hopper part occupies a certain height of the cylinder body, and the storage capacity is influenced. The larger the diameter of the bin is, the more cone hoppers are required, and the more bin matching equipment on the bin and the more discharging equipment under the bin are required.

The filling factor of the large-diameter silo is low. Because the large-diameter cylindrical bin has large bin allocation area and is limited by the function of bin allocation equipment, the upper part of the bin cannot be filled in any way, so that the bin capacity is reduced; the energy consumption of the equipment is high. Due to the large distribution surface, the material can be separated only by lifting the upper bin rubber belt conveyor to a certain height, so that more equipment and more power consumption are realized; the capping construction difficulty on the bin is large.
