摘要： A device for coating surfaces of a powdered material, comprising a combination of a powdered material introduction portion (A) operating by coanda flow or coanda spiral flow, and a coanda spiral flow generation portion (B) for blowing a liquid coating material atomized by diffused gas, surfaces of the powdered material being coated by blowing a liquid coating material atomized by diffused gas through the coanda slit (3) into the powdered material conveyance passage (1) by coanda flow or coanda spiral flow. The method prevents the powdered material from coagulating and applies an even and highly efficient coating to its surfaces.
