The present invention relates to a lift bar for a rotational ball-mill drum. The lift bar can easily block the inflow of ground particles through the gap between rubber plates forming the inner walls of the rotational drum and the rubber lift bar. Accordingly, the rotational ball-mill drum (20) can grind minerals stored on the inside by being rotated by the rotational power delivered from a driving motor (10). Multiple rubber plates (30) are formed on the inner walls of the rotational drum (20) at predetermined intervals. The rubber lift bar (40) is coupled to the rubber plates (30) while protruding by a predetermined height. An inflow blocking jaw (41) protrudes from both side walls of the rubber lift bar (40) to block the inflow of the ground particles through the gap between the rubber lift bar (40) and the rubber plates (30). |
