The present invention provides a powder coating regeneration method, which comprises the steps of: pulverizing the waste powder coating by putting the waste powder coating into a grinder; removing foreign substances from the pulverized waste powder coating; discharging the waste powder coating from which the foreign substances have been removed in a vacuum; and collecting the discharged waste powder coating as regenerated powder coating. 본 발명은 폐분체도료를 분쇄기에 투입하여 분쇄하는 단계; 분쇄된 폐분체도료로부터 이물질을 제거하는 단계; 이물질이 제거된 폐분체도료를 진공상태에서 배출하는 단계; 및 배출된 폐분체도료를 재생 분체도료로 수거하는 단계;를 포함하는 분체도료 재생방법을 제공한다.
