To provide a separator for used sanitary article processing equipment which can shorten a processing time in the used sanitary article processing equipment which can separate a used sanitary article into plural kinds of blanks which constitute a sanitary article, and can sort the used sanitary article for each of the plural kinds of blanks.SOLUTION: A separator 4 for used sanitary article processing equipment comprises: a housing 7； an outer barrel separation tank 8； an inner barrel separation tank 9； a decomposition water supply part 10 which is provided on the housing 7, and supplies decomposition water 3, in which at least water, lime and a bactericidal agent are mixed at a prescribed ratio, into the inner barrel separation tank 9 while sprinkling said decomposition water onto a used sanitary article 2 from above the used sanitary article 2 which has been introduced into the inner barrel separation tank 9 in the state that the inner barrel separation tank 9 is rotated at a prescribed rotation frequency； and a discharge part 5 which is communicated with a lower side of the outer barrel separation tank 8, and discharges waster water containing dirt together with decomposition water in the outer barrel separation tank 8. By rotation of the inner barrel separation tank 9, the introduced used sanitary article 2 is immersed in decomposition water and is separated to plural kinds of blanks which constitute the sanitary article 2, and the separated plural kinds of blanks are dehydrated.SELECTED DRAWING: Figure 3【課題】衛生用品を構成する複数種の素材に使用済み衛生用品を分離し、複数種の素材ごとに選別することができる使用済み衛生用品の処理装置において、処理時間を短縮することができる使用済み衛生用品の処理装置用分離機を提供する。【解決手段】本発明の使用済み衛生用品の処理装置用分離機４は、筐体７と、外胴分離槽８と、内胴分離槽９と、筐体７に設けられ内胴分離槽９内に、少なくとも水と石灰と殺菌剤とが所定の割合で混合された分解水３を、内胴分離槽９を所定の回転数で回転させた状態で、内胴分離槽９内に投入された使用済み衛生用品２の上部から使用済み衛生用品２上に撒き散らして供給する分解水供給部１０と、外胴分離槽８の下部側と連通され外胴分離槽８内の分解水とともに汚物を含む排水を外部へ排出する排出部５と、を備え、内胴分離槽９の回動により、投入された使用済み衛生用品２が分解水に浸漬されて衛生用品２を構成する複数種の素材に分離され、分離された複数種の素材が脱水される。【選択図】 図３
