Description

technical field [0001] The invention relates to the technical field of slime separation, in particular to an efficient and environment-friendly slime separation device. Background technique [0002] Accumulative bauxite is the main source of aluminum production in South China. Its typical feature is high mud content, accounting for about 60% of the original ore. During production and processing, about 60% of the clay in the raw ore must be removed by means of ore washing to obtain clean aluminum concentrate. [0003] The application number is 201510602844.8, and the patent name is a kind of slime separator. This utility model includes a dust cover and a double-layer drum screen rotatably arranged in the dust cover; The cylindrical inner trommel and the cylindrical outer trommel are coaxially arranged; the upper end of the inner trommel is provided with a feed port, and the lower end is provided with a coarse ore discharge port. The bauxite is first dried, and at the same ti...
