Claims

[Claims for Utility Model Registration] (1) A ball mill comprising a main body enclosing balls and pulverized material, and a drive mechanism for rotating the main body, and pulverizing the material by the balls as the main body rotates. A ball mill characterized in that a convex portion and/or a concave portion is formed on the inner circumferential surface of the main body. (2) The ball mill according to claim 1, wherein the convex portions and concave portions are protrusions and grooves extending in the direction of the rotation axis of the main body. (3) The ball mill according to claim 1, wherein the lid of the main body is provided with a pin that protrudes toward the internal space of the main body.
