PROBLEM TO BE SOLVED: To provide a polishing grain replacing device for efficiently and easily treating stained polishing grains to the washing treatment because a conventional polishing grain replacing device has only a function of reserving new and used polishing grains and time and effort is required for washing, drying and storing the stained polishing grains. SOLUTION: The polishing grain replacing device consists of a tank unit with integrated tanks for supply and collection, a blower disposed above the tank for collection, a washing machine consisting of a washing tub and a drum, a hose for collection for collecting polishing grains, a hose for supply for supplying polishing grains, a pump for feeding washing water to the washing machine, a pump for draining water from the washing machine, and a tank for reserving washing water used to feeding/draining water.
