Efficient ball mill for processing cement

The utility model discloses an efficient ball mill for processing cement. The efficient ball mill comprises an outer barrel, an inner barrel, a feeding hopper, bulges, a discharging hopper, a filter screen, a discharging opening, a grinding ball filling hole, an air pressure sensor, an exhaust tube, a vacuumizing machine, fixed shafts, rotary motors, bearings, supporting columns and supporting bases. According to the efficient ball mill, the discharging hopper is arranged at the bottom of the inner barrel, so that materials are conveniently collected, the filter screen can be replaced according to the need, and the convenience of the ball mill in use is improved; the vacuumizing machine can vacuumize the inner barrel to enable the interior of the inner barrel of the ball mill to be in the vacuum environment, so that the working efficiency is improved; a plurality of bulges are arranged on the inner wall of the inner barrel, so that the grinding effect and the working efficiency of the ball mill are improved; the bearings are arranged at the contact parts of the fixed shafts and the outer barrel, so that friction between the shafts and the outer barrel is avoided and the service life of the ball mill is prolonged; a sound insulation sponge layer is arranged between the outer barrel and the inner barrel, so that noises generated during working of the ball mill are reduced and the working environment of operators is improved.
