Technical Field

[0001] The utility model relates to the technical field of liners, in particular to a gyratory liner made of high-strength wear-resistant alloy steel. Background Art

[0002] A gyratory crusher, namely a vertical compound crusher, also known as a compound crusher, is a machine in a crushing production line and a sand-making production line. Liners are installed on the inner wall of the gyratory crusher. The liners protect the cylinder body from the direct impact and wear of grinding media and materials, and improve the service life of the device.

[0003] The utility model patent with the publication number of CN212632796U discloses a gyratory crusher liner, which includes an upper-piece movable cone liner, a lower-piece movable cone liner, a first-layer fixed cone liner, a second-layer liner, and a third-layer liner. The upper-piece movable cone liner and the lower-piece movable cone liner are respectively fixed up and down outside the movable cone main shaft body. Wave-shaped protrusions are provided on the contact surface between the upper-piece movable cone liner and the lower-piece movable cone liner. Inside the crusher frame body, the first-layer fixed cone liner, the second-layer liner, and the third-layer liner are arranged in sequence from top to bottom.

[0004] However, there are still certain deficiencies in the above technical solution: in the above technical solution, there is no connection between the multi-layer liners, which makes it possible for the liners inside the cylinder to be loose. Furthermore, during crushing, the liners are prone to collide with each other, which leads to the loosening of the fixation of the liners, and then affects the use of the overall structure.

After installing multiple lining plate bodies, install the clamping block through the second positioning bolt to limit the top lining plate body, achieving the limiting effect on multiple lining plate bodies and avoiding loosening during crushing.

[0010] As a further solution of the present utility model: A plurality of hemispherical protrusions are fixedly installed on the inner wall of the lining plate body. The lining plate body is composed of a wear-resistant inner layer, a base layer, and an anti-collision outer layer. The wear-resistant inner layer is located inside the lining plate body, the anti-collision outer layer is located outside the lining plate body, and the base layer is located between the wear-resistant inner layer and the anti-collision outer layer.

[0011] By adopting the above technical solution, during use, the hemispherical protrusions improve the friction effect, thereby increasing the crushing speed.

[0012] As a further solution of the present utility model: A plurality of annular steel bars are installed inside the base layer.

[0013] By adopting the above technical solution, during use, the steel bars improve the strength of the overall lining plate body.
