The crushing wall is one of the main components of the cone crusher, also known as the moving cone, which is fixed on the cone body with a cone head. The crushing wall of the cone crusher is forged with new composite materials, which has the characteristics of strong wear resistance, high cost performance, and wide application fields. The cone crushing wall is fixed on the cone body by the cone head, and epoxy resin is cast between the two. After the newly installed or replaced cone crushing wall has been working for 6 to 8 hours, the tightening of the cone should be checked and found to be loose immediately. Fasten.
The structure of cone crusher mainly includes frame, horizontal shaft, moving cone, balance wheel, eccentric sleeve, upper crushing wall (fixed cone), lower crushing wall (moving cone), hydraulic coupling, lubrication system, hydraulic system, The control system is composed of several parts.
When the cone crusher is working, the surface of the crushing wall is sometimes close to and sometimes away from the surface of the rolling mortar wall, so that the material is continuously squeezed, impacted and bent in the annular crushing cavity composed of the upper and lower crushing walls to be crushed.
Manganese 13 (Mn13) rolling mortar wall broken wall
Mn13 has high tensile strength, plasticity, toughness, and non-magnetic. Even if the parts are worn to a very thin thickness, they can still withstand large impact loads without breaking. It can be used to cast various impact-resistant wear parts.
Manganese 13 chromium 2 (Mn13Cr2) rolling mortar wall broken wall
The use of Mn13Cr2 material, that is, while reducing the content of C and Mn in the traditional high manganese steel, the Cr element is added to make up for the lack of toughness of the traditional high manganese steel and effectively extend the service life of wear-resistant parts.
Manganese 18 (Mn18) rolling mortar wall broken wall
Especially the standard Mn18 high manganese steel rolled mortar wall, which contains high manganese and carbon content; the as-cast structure of the steel is austenite and carbides. After 1050℃ water toughening treatment, most of the carbides are dissolved in austenite In the body.
