Document Type and Number:
WIPO Patent Application WO/2021/166731
Kind Code:
A1
Abstract:
The present invention pertains to a particulate matter spraying method comprising a step for conveying, in a prescribed direction by a conveying means (3), a particulate matter (P) discharged from a hopper (2) and spraying said particulate matter. Said spraying method further comprises: a first conveyance capacity control step for controlling the conveyance capacity of the conveying means such that a spray volume per unit time (ΔS) of the particulate matter (P) matches a target spray volume per unit time (ΔSt) while measurements are being continuously made of the total mass of the hopper and the particulate matter kept inside the hopper (i.e., the total mass of the particulate matter inclusive of the hopper); and a second conveyance capacity control step (C2) for controlling, if a measured total mass (B) of in-hopper particulate matter becomes lower than a threshold, the conveyance capacity of the conveying means by a method different from that for the controlling in the first conveying capacity control step while the particulate matter (P) is being replenished in the hopper until the total mass of the in-hopper particulate matter becomes equal to an initially set mass (B0).
