FIELD: transport.SUBSTANCE: invention may be used in air separation units, helium cryogenic system driers, natural gas liquefying units, oil and chemical industry, etc. For granules loading purposed, granule unloading tubes are equipped with controlled rate shutoff devices. Prior to loading granules with closed shutoff devices, the container is filled with drop material composed of, for example, dry clean solid plastic 0.8-1.5D-dia balls where D is maximum diameter of granules. Then shutoff devices are opened to load granulated material via loading tubes to complete discharge of drop material to close shutoff device. At equal rates of drop material unloading and granulated material loading, granules drop smoothly in said container without collapse of granules and dust formation.EFFECT: ruled out destruction of granules. |
