[0002] At present, multi-cylinder cone crushers are widely used in the medium and fine crushing of materials in the mining, smelting, building materials, water conservancy and other industries. Multi-cylinder cone crushers are mainly composed of a frame, a support sleeve, an adjustment sleeve, an eccentric sleeve and other parts. The transmission device drives the eccentric device to rotate, and the moving cone rotates and swings under the action of the eccentric sleeve, forming a crushing chamber with the mortar wall fixed on the upper frame. The material is crushed by the swinging extrusion and impact of the moving cone. The balance ring of the multi-cylinder cone crusher and the moving cone are connected at the joint with a seal. When the material is crushed in the cone crusher, fine dust will be generated. If the seal is not used for dust prevention, the fine dust will enter the main machine through the joint, polluting the circulating lubricating oil of the main machine, shortening the effective life of the lubricating oil, and when the pollution is serious, it will damage the parts inside the cone crusher.

[0003] At present, the sealing methods of existing multi-cylinder cone crushers are as follows: Figure 2 As shown, by machining mounting grooves on the moving cone 1 and the balance ring 3, a labyrinth structure is formed with the T-shaped sealing ring 2 to prevent dust. This sealing method has strict machining requirements for the mounting grooves on the moving cone 1 and the balance ring 3, and has a large usage and bonding requirements for the adhesive of the T-shaped sealing ring 2.
