Application of Rotary Crushers in Ore Crushing and Development of Wear-Resistant Component Technologies
2025-02-18
The gyratory crusher has a long history of application in the industrial sector and continues to be widely used today in large- and medium-sized beneficiation plants as well as other industrial departments, primarily for crushing ores and rocks of varying hardness. Wear-resistant parts for gyratory crushers It mainly includes the moving cone liner and the stationary cone liner, and the space formed between the two is called the crushing chamber.
During the operation of a gyratory crusher, ore located near the fixed cone is crushed due to compressive and bending forces; meanwhile, in the area where the moving cone is farther from the fixed cone, the already-crushed ore is discharged under the influence of gravity. The lower lining plate of the moving cone serves as Wear-resistant parts for gyratory crushers Key components are equipped with replaceable annular manganese steel liners on their outer surfaces to prevent wear. These liners are securely bonded to the cone using either cast zinc alloy or epoxy resin, enhancing both the liner’s strength and its precise fit. The cone is fitted to the spindle via a press fit, again secured with a layer of cast zinc alloy; however, modern, advanced equipment now integrates the cone and spindle into a single, monolithic structure. At the bottom end of the spindle sits an upper friction disc, whose base features a convex spherical surface that perfectly matches the complementary spherical shape of the middle friction disc.
Duma Machinery, as a professional Wear-resistant parts for gyratory crushers The manufacturer is dedicated to enhancing the performance of crushing walls and grinding bowls.
