Liners with high resistance to wear (MMD)
Liners with high resistance to abrasion are made up of a tempered steel support with insertion of a tungsten carbide strip.
Tungsten carbide is a material with high resistance to abrasion, mainly made of carbon and tungsten, and used, among other applications, in the manufacture of tools for working on steel and other very hard materials. They are fixed or extractible liners, made with the same structure as the rest of the liners, in which tungsten carbide blades are inserted. These Liners have Rockwell C hardness of 75 to 80 and are able to resist 3 to 5 million pressing cycles, thereby multiplying the useful lifespan of the liners by at least 4.
