Abstract
The ball mill comprises a rotatably mounted casing (1) with lined internal surface and lined end-face bottoms (2,3), provided with inlet (4) and outlet (5) openings. It contains inside at least one perforated partition (6) oriented at an angle (alpha) to its longitudinal axis and dividing the casing into coarse-grinding and fine-grinding chambers (8,9) filled with grinding bodies. - The lined internal surface of the chambers is shaped as truncated cones facing with their larger bases the perforated partition (6), the angle of inclination of the generatrices (12,13) of which is equal to the angle of natural slip of the grinding bodies contained in the corresp. chamber. The volume of the coarse-grinding chamber (8) is smaller than that of the fine-grinding chamber USAB- US4867322 A The ball tube mill includes a rotatable housing with a lined inside surface and end cover plates having an inlet hole and an outlet hole and accommodating at an angle to is longitudinal axis at least one perforated wall dividing the housing into coarse and fine grinding chambers charged with grinding bodies. The lined inside surface of the chambers has the form of truncated cones facing by their large bases the perforated wall. The angle of inclination of a generating line of the truncated cones equals the angle of the slope of the grinding bodies present in the respective chamber. The volume of the coarse grinding chamber is smaller than the volume of the fine grinding
