Cone Crusher Bowl liner

The mantle of cone crusher is one of the key components of cone crusher. It is the inner wall of the crushing chamber and usually consists of several conical tooth-shaped protrusions. Its working principle is as follows: when the cone crusher is turned on and operates normally, the material is fed into the crushing chamber. Due to the rotation of the mantle and the free fall of the material, the material will collide and be crushed multiple times between the mantle and the concave. In terms of manufacturing process, the following are common: 1. Material selection: Commonly used materials include medium manganese steel (mn8), high manganese steel (such as mn13-3, mn13-4, mn13gr2), ultra-high manganese steel (mn18, mn18gr2), etc. Different materials have different characteristics. For example, high manganese steel has high tensile strength, plasticity and toughness, and weak magnetism. Under high-speed and heavy-load conditions, a work hardening layer will be formed on the working surface, which has good wear resistance. And even if the part is worn very thin, the austenite inside can still withstand large impact loads without breaking. 2. Casting process: such as lost foam casting, quartz sand molding casting, resin sand molding casting, etc. 3. Some special manufacturing processes: - Adopting bimetallic composite wear-resistant parts: Hard alloy is inlaid and compounded at the working part, so that the wear surface of the mantle has excellent wear resistance and improves the service life of wear-resistant parts. - New composite mantle: Cast from a new high-performance composite material, with a long service life. For example, the service life is more than three times longer than that of ordinary mantles. The research and development process usually requires wear-resistant material experts to conduct long-term research and experiments to determine a reasonable element ratio and an optimized heat treatment process. - Combined component form: The mantle can be designed as a combined component. According to different wear conditions, the component can be divided into several parts with different materials and connected by bolts. The connecting bolts can also form a wear-resistant belt to protect the mantle at the same time. A hemispherical part and other protective structures can be detachably installed on the bolt head to further protect the bolt from wear. In addition, during the manufacturing process, some details need to be paid attention to. For example, strictly control the parameters such as temperature and composition during the casting process to ensure the quality and performance of the mantle. Conduct strict quality inspections on the product, including inspections of dimensional accuracy, hardness, wear resistance, etc., to ensure that it meets relevant standards and requirements. The advantages of the cone crusher mantle include: 1. High strength: It can withstand high-power crushing force, ensuring the stability and durability of the equipment. 2. Wear resistance: The surface is specially treated and has high wear resistance. It is not easy to wear after long-term use, reducing the frequency of replacing parts and lowering operating costs. 3. Impact resistance: The structural design can withstand the action of large impact force and is not easily damaged when crushing hard materials, improving the service life of the equipment. 4. Energy saving and environmental protection: Adopting advanced crushing technology can realize full crushing and screening of materials, improve production efficiency, and reduce noise and dust generation. In practical applications, it is necessary to select a mantle with appropriate material and manufacturing process according to specific working conditions and material characteristics to ensure the normal operation and efficient work of the cone crusher. At the same time, reasonable operation and maintenance also help to extend the service life of the mantle.
