Description

Technical Field

[0001] The utility model belongs to the technical field of ball mill liners, and particularly relates to a ball mill liner which is convenient to replace. Background Technique

[0002] The ball mill liner is an important component of the ball mill. The ball mill liner is used to protect the cylinder body of the ball mill, so that the cylinder body is not directly impacted and rubbed by the grinding medium and the material. At the same time, different forms of liners can be used to adjust the motion state of the grinding medium to enhance the crushing effect of the grinding medium on the material. The ball mill liner helps to improve the grinding efficiency of the ball mill.

[0003] After retrieval, the publication number is CN211755616U, which provides a ball mill liner. The ball mill liner includes a connecting bottom plate and a liner body; the connecting bottom plate is a fan-shaped ring, and the fan-shaped connecting bottom plate includes a first inner arc surface. A connecting groove is arranged on the first inner arc surface, and a plurality of arched leaf springs are arranged at the bottom of the connecting groove. The axial direction of the arched leaf spring is parallel to the axial direction of the connecting bottom plate; the liner body is adapted to the connecting groove, and the liner body is arranged in the connecting groove. The liner body includes a second inner arc surface and a second outer arc surface. Both the second inner arc surface and the first inner arc surface are arranged as wavy curved surfaces and are located on the same circumference. The arched surface of the arched leaf spring contacts the second outer arc surface.

[0004] However, the above application has the following defects in the process of its implementation:

[0005] Most of the liners in the existing ball mills are of an integral structure. After long-term use, the internal liners may be locally worn after long-term friction and impact with the grinding medium and the material, and need to be replaced later. However, the replacement process of the integral ball mill liner is too cumbersome, and the liners in the ball mill cannot be utilized to the maximum extent, and the applicability is low.
