The rolling mortar wall is an important part of the cone crusher. It forms the cone crusher together with the frame, horizontal shaft, moving cone, balance wheel, eccentric sleeve, lower crushing wall, hydraulic coupling, lubrication system, hydraulic system, and control system. . Also called: broken wall, fixed cone liner, cone crusher liner, cone crusher liner, static cone, fixed cone, crushing plate.

Cone crusher, cone crusher, cone crusher, cone crusher, cone crusher, cone crusher, gyratory crusher, etc.
Cone crushers are widely used in the mining industry, metallurgical industry, construction industry, road construction industry, chemical industry and silicate industry. It is suitable for crushing hard and medium hard ores and rocks, such as iron ore, limestone, copper ore, Quartz, granite, sandstone, etc.
Structure and Characteristics
Since the wall of the rolling mortar is connected by zinc alloy casting, check its firmness after the equipment has been running for a period of time to see if the fastening is intact. The connection between the wall of the rolling mortar and the adjusting ring is fixed by U-shaped fixing screws, and a zinc alloy is cast between the wall of the rolling mortar and the adjusting ring to make it tightly combined. When replacing a new rolling mortar wall, you must pay attention to its fixation, and after the installation is complete, you also need to pay attention to check its firmness after a period of operation to ensure that it will not loosen or fall off. You can fix it by tightening the fixing screws.
The crushing wall and the rolling mortar wall are the main components that work together in the cone crusher and crush the material. When the cone crusher is in operation, the crushing wall will move in a trajectory, and the distance from the wall of the rolling mortar will be close and sometimes far away. The material is crushed by multiple squeezing and impacts of the crushing wall (moving cone) and rolling mortar wall (fixed cone) , At this time, part of the material will be discharged from the open side discharge port. In the cone crushing station, the crushing wall and the rolling mortar wall are the main components that directly contact the material. After a period of use, it will inevitably produce wear.
In general, the crushing wall and rolling mortar of a cone crusher can theoretically be used for 6 months, but it is understood that some users need to replace it after 2-3 months of use. This is because its service life is affected by a variety of different factors, resulting in different wear conditions. In the course of use, when the thickness of the crushing wall and rolling mortar of the cone crusher is worn to two-thirds, or cracks occur, and the discharge port is enlarged to be unable to adjust, it needs to be replaced.
