PROBLEM TO BE SOLVED: To provide a continuous abrasion testing device capable of performing an abrasion test not in a batch style but continuously in succession without opening a lower tank or an upper tank, and improving efficiency. SOLUTION: This device includes the upper tank 1 for storing powder and granular material S, an abrasion test part 2 for allowing the powder and granular material S dropped from the upper tank 1 to collide with a test piece T to abrade the test piece T, and the lower tank 3 for receiving the powder and granular material S colliding with the test piece T in the abrasion test part 2. The device additionally includes a conveyance means 11 for returning the powder and granular material S received by the lower tank 3 into the upper tank 1, and an integrated flow rate measuring means 12 for measuring an integrated flow rate of the powder and granular material S returned into the upper tank 1 by the conveyance means 11.
