Abstract

The present disclosure relates to a slurry mixer for a secondary battery electrode material and a secondary battery manufacturing apparatus including the slurry mixer. The slurry mixer includes an inner cylinder including an inner cylinder body configured to accommodate a slurry to be mixed and an upper support member having a ring shape and fixed to an upper end portion of the inner cylinder body. An outer cylinder including an outer cylinder body is configured to rotatably accommodate the inner cylinder, with the outer cylinder including a fixed flange fixed to the upper end portion of the outer cylinder body, and the outer cylinder including a cover mounted on the fixed flange and positioned on the upper support member. An elastic sealing portion is mounted on the cover, with the elastic sealing portion being elastically deformable, the elastic sealing portion including a lower end portion in contact with the upper support member, and the elastic sealing portion being configured to prevent the slurry from leaking through a space between the cover and the upper support member.
