PURPOSE:To produce a fused flux contg. no water with less driving power in such a way that the grain size thereof can be adjusted by running downward the molten flux, bringing the flux into collision against a flow regulating plate consisting of a cooled rotary circular truncated cone, and granulating the flux. CONSTITUTION:A cooled granulator 3 is provided with a granulating plate 13 consisting of a rotary circular truncated cone body supported by a revolving shaft core 26, a revolution transmission pipe 27, a suspension hook 12, etc., a water sprayer 18 which ejects cooling water from many sprinkling ports 38 and cools said plate 13 from the rear, a water recoverer 36 which collects and discharges the cooling water, and a flux receiver 20 which rotates and has an annular and sectionally recessed shape. The molten flux charged from a melting furnace 1 into a charging furnace 2 in such a device 3 is dropped onto the plate 13 through a feed port 2a by tilting the furnace 2 to bring the flux into collision against said plate, whereby the flux is cooled and granulated. The grain size thereof can be easily adjusted by the position of the melt falling onto the plate 13, the rotating speed of the plate, etc. The scattering of the granules is prevented by an anti-scattering plate 19 and the granules are dropped into the receiver 20, from which the granules are taken out through a suction pipe 37. |
