[0014] In order to further describe the utility model, the utility model discloses a ball mill ore drawing operation device in further detail below in combination with the drawings and examples.

[0015] A ball mill ore drawing operation device is suitable for all ball mill ore drawing operations. The device is conical through the ore drawing cabletow cage 1, and is internally provided with the spiral grid block 2, so that the coarse aggregate is conveniently discharged and smoothly discharged into the receiving hopper, and the coarse aggregate is prevented from falling into the ore drawing pool, and the problem of the blockage of the inlet of the slurry pump is effectively avoided. The device is connected with the ball mill through the flange 3, so that subsequent installation and maintenance are facilitated, and the normal needs of production can be met. The device is provided with a plurality of apertures 4 on the surface of the taper of the ore drawing cabletow cage, so that the slurry is conveniently discharged.

[0016] The slurry and the coarse aggregate enter the ore drawing cabletow cage through the discharge end of the ball mill, the ball mill drives the ore drawing cabletow cage to rotate, the slurry falls into the ore drawing pool through the apertures on the surface of the ore drawing cabletow cage, and the coarse aggregate is moved to the outlet of the ore drawing cabletow cage through the centrifugal force of the internal grid block of the ore drawing cabletow cage and falls into the receiving hopper.

[0017] The utility model discloses a ball mill ore drawing operation device, contain: connecting flange, ore drawing cabletow cage, internal spiral grid block etc. The slurry and the coarse aggregate enter the ore drawing cabletow cage through the discharge end of the ball mill, the ball mill drives the ore drawing cabletow cage to rotate, the slurry falls into the ore drawing pool through the apertures on the surface of the ore drawing cabletow cage, and the coarse aggregate is moved to the outlet of the ore drawing cabletow cage through the centrifugal force of the internal grid block of the ore drawing cabletow cage and falls into the receiving hopper.

[0018] Through the installation of the discharge cage, the smooth entry of the slurry into the discharge pool and the fall of the coarse aggregate into the receiving hopper are effectively ensured, and the equipment operation rate and the subsequent maintenance frequency are effectively improved.
