PROBLEM TO BE SOLVED: To provide a centrifuge in which sludge with high specific gravity like machining chips is automatically discharged timely before accumulating much in a rotary bowl. SOLUTION: This separation plate type centrifuge is provided with a vertical rotary shaft 2 driven by a rotary driving means 1, the rotary bowl 3 mounted on the vertical rotary shaft 2 coaxially and integrally rotatably with it, and a treating liquid supply part 5 supplying treating liquid into the rotary bowl 3, and separates the treating liquid A supplied to the rotary bowl 3 into cleaned water a<SB>2</SB>, oil a<SB>1</SB>and sludge a<SB>3</SB>by the action of a centrifugal force caused by the rotation of the rotary bowl 3. Discharge ports 10 are penetratingly provided on the circumferential wall of the rotary bowl 3 with certain intervals in the circumferential direction discharging the sludge a<SB>3</SB>attached on the inner circumferential face of the bowl 3. Each discharge port 10 is provided with a valve mechanism 11 for opening/closing the discharge port in such a manner that a member constituting the valve mechanism 11 does not protrude from the outer circumferential face, penetratedly provided with the discharge port, of the circumferential wall of the rotary bowl 3.
