Manufacturing method of cemented carbide bead

摘要

The present invention relates to an apparatus for manufacturing a carbide alloy bead, and more particularly, to a device for manufacturing an ultra-small sized carbide alloy bead utilizing ion exchange reaction and electric charge (or static electricity). Carbide alloy bead production apparatus of the present invention for achieving the above object is a stirring tank for preparing a slurry by stirring the bead molding material is added; A vacuum tank arranged adjacent to the stirring tank to remove bubbles of the slurry discharged from the stirring tank through the first transfer pipe; A second transfer pipe having one end connected to the vacuum tank and transferring slurry discharged from the vacuum tank; A nozzle unit connected to the other end of the second transfer pipe and dropping the slurry transferred from the second transfer pipe; A first reaction vessel in which a space for accommodating the reaction solution is formed, the lower portion is tapered toward the inside, and the slurry dropped on the reaction solution from the nozzle portion is solidified to produce beads; It is characterized in that it is provided spaced apart from the lower portion of the first reaction vessel, a second reaction vessel for collecting beads from the first reaction vessel through a third transfer pipe.
