The gyratory crusher is widely used in various industrial fields, especially in large and medium-sized mineral processing plants and related industries, primarily for crushing ores and rocks of different hardness. The main gyratory crusher wear parts include the lower concave liner (movable cone) and the upper concave liner (fixed cone), with the gap between them referred to as the crushing chamber.
During operation, ores located between the movable and fixed cones are crushed due to compression and bending forces. The crushed ores are then discharged by gravity as the movable cone moves away from the fixed cone. The movable cone, as a key component of the crusher, is typically fitted with replaceable ring-shaped manganese steel liners on gyratory crusher wear parts outer surface to prevent wear. A layer of zinc alloy or epoxy resin is poured between the liners and the cone body to enhance their strength and fit. The cone body and the main shaft are statically fitted, with zinc alloy poured between them, and newer equipment typically integrates the cone body and main shaft into a single unit. The bottom end of the main shaft is securely connected to the upper friction disc, which is in contact with the convex spherical surface of the middle friction disc.
Duma Machinery is a professional gyratory crusher parts Manufacturer. To improve the performance of the crushing mantle and bowl liner, the company has conducted extensive research on alloying, micro-alloying, carbon-manganese content adjustments, and precipitation strengthening treatments. The newly developed composite material bowl liners and crushing mantles have been widely used in production practices, gyratory crusher wear parts receiving unanimous praise from customers.
