Stirred ball mill without retaining device for grinding media

Abstract

The present invention relates to a grinding outlet 10 for a stirred ball mill 20, wherein the stirred ball mill 20 has a cylindrical basic shape, wherein the stirred ball mill 20 has an outlet opening 22, wherein the outlet opening 22 is arranged on a cylindrical end face of the stirred ball mill 20, wherein the stirred ball mill 20 has a centrally arranged shaft 30 and a grinding area between the shaft 30 and the cylindrical outer wall, wherein the grinding area has a first radius rM between the shaft 30 and the outer wall, wherein the grinding outlet 10 has an inlet opening 12, a gas deflection and a gas outlet 14, wherein the inlet opening 12 is arranged in the inner region of the cylindrical end face at half the first radius 0.5 rM from the shaft 30 and is not located in the outer region at half the first radius 0.5 rM from the outer wall.wherein the gas deflection deflects the gas flow, which in a first approximation comes parallel to the axial direction of the stirred ball mill 20, upwards against gravity, wherein the gas outlet 14 is arranged above the shaft 30.
