Abstract

PURPOSE: To provide a granular material loading method, according to which granular material is released and dropped with its flow being contracted, after fine powder is scattered out of the granular material and the dropping speed is lowered with the upper portion of granular-material dropping passage being shielded from the outside, whereby it is enabled to lower the void vatio of granular material by reducing the dropping speed at the end portion of the passage and to prevent scattering of fine powdery material to the surroundings if such material is contained in the granular material.
CONSTITUTION: Upper portion 3A of granular-material dropping passage 3 is enclosed by wind- shield 2 connected to the outlet port 1, and granular-material releasing port 3B at the end portion of passage 3 is arranged to be retractable to vary its level for facilitating insertion of the same into a container into which granular material is to be loaded. Vanes 4 are provided in the vicinity of the lower end of wind-shield 2 in passage 3 for decelerating the dropping speed of granular material and for discharging fine powdery material to the outside of passage 3A. On the other hand, void ratio of granular material is lowered by contracting the passage 3A while decelerating the speed of granular material by means of reducer 5 connected to the lower end of wind-shield 2, and then granular material is dropped into the container through releasing port 3B. Further, fine powdery material discharged to the outside of passage 3A in wind-shield 2 is recovered by suction means 6 connected to wind-shield 2 and to an upstreams portion of passage 3.
