Description

Technical Field

[0001] The utility model relates to the technical field of ball mill lining plates, in particular to a ball mill lining plate which is easy to disassemble and assemble. Background Art

[0002] Domestic high manganese steel is gradually replaced by medium alloy steel lining for ball mill linings. However, with the continuous application of medium alloy steel linings in ball mill linings, it has gradually replaced manganese steel and other linings to become the mainstream of market development. In addition to protecting the cylinder, the cylinder lining also affects the movement of the grinding body. In order to adapt to the requirements of various working conditions (crushing or fine grinding), the shape and material of the lining are also different. When crushing is the main operation, the lining is required to have a strong ability to push the grinding body, and the lining should have good impact resistance. When fine grinding is the main operation, the protrusion of the lining is relatively small, the pushing effect on the grinding body is weak, the impact is small, and the grinding effect is strong, so the lining is required to have good wear resistance.

[0003] China Authorization Announcement No. CN215234717U discloses a new type of ball mill liner, including a base plate, which is annular and assembled from a plurality of arc-shaped bases. The base plate and the ball mill cylinder are detachably fixed, and also include: a wear-resistant roller seat, wherein the wear-resistant roller seat is provided with a plurality of wear-resistant roller seats and is arranged on the inner wall of the base plate, and an inner polygonal raceway for the movement of grinding steel balls is formed between the plurality of wear-resistant roller seats. The new type of ball mill liner provided by the utility model is easy to disassemble and replace, can grind materials quickly, and has a wear-resistant effect through the arrangement of the wear-resistant roller seat. At the same time, it can reduce the wear on the ball mill cylinder, and the overall structure is stable.
