Slag-water separation device and method for uranium dioxide pellet grinding

The invention belongs to the technical field of nuclear fuel components and particularly relates to slag-water separation device and method for uranium dioxide pellet grinding. The device comprises a clarifying tank and a centrifugal separating device, wherein the clarifying tank comprises a liquid lifting tank, a dirty liquid tank and a clean liquid tank which are adjacent to one another; an overflow port is arranged between the liquid lifting tank and the dirty liquid tank and an overflow port is arranged between the dirty liquid tank and the clean liquid tank to allow the liquid lifting tank, the dirty liquid tank and the clean liquid tank to keep a safety liquid level. The slag-water separation device and method has the advantages that the technical problem that an existing manual slag removing method affects production continuity is solved, automatic slag removing can be achieved, low time consumption is achieved, production continuity is affected, a good and stable grinding slag separating effect is ach
