Wet stirred ball mill

摘要

A vertical wet stirred ball mill is provided according to this invention, wherein a slurry raw material fed from the top of the mill body is stirred together with a grinding medium in said mill body under pressure and the material is gradually exhausted from the bottom of said mill body as it is milled. A spring-loaded conical separation valve is fitted at an exhaust port of said body. The separation valve retracts when the pressure within the mill body is increased due to plugging, thereby the annular clearance around the separation valve is enlarged to increase the amount of exhaust, leading to elimination of the plugging.
