Cone Crusher Mantle Concave Liners High Manganese Chrome Alloy Mining Wear Parts

Cone Crusher Mantle Concave Liners High Manganese Chrome Alloy Mining Wear Parts

Product Description

This product consists of the mantle liner and concave liner for cone crushers, which are the core wear parts used in the crushing cavity. The mantle is mounted on the main shaft and performs a gyratory motion driven by the eccentric sleeve, while the concave is fixed on the adjustment ring. Together they form the crushing chamber and crush materials through extrusion, bending and impact. As direct contact wear parts, the material selection, casting quality and cavity design of the mantle and concave directly affect crushing efficiency, product size, equipment uptime and operating cost.

Cone crushers can be classified into spring cone crushers, single cylinder hydraulic cone crushers, multi cylinder hydraulic cone crushers and compound cone crushers. The mantle and concave for different models vary in shape, size, mounting method and cavity profile. We can produce mantle and concave liners to match various cone crusher models based on the model number, drawings or physical samples provided by customers, meeting the requirements of different crushing processes for cavity profile and product size.

Alloy steel liners combine strength and wear resistance through alloying element control and heat treatment adjustment. Ductile iron liners have good comprehensive mechanical properties and damping performance, suitable for specific working conditions. Customers can choose the appropriate material solution based on actual working conditions and budget.

Applications

This product is suitable for secondary and tertiary crushing with cone crushers, widely used in crushing production lines in mining, metallurgy, building materials, highway, railway, hydropower and chemical industries. It can process iron ore, copper ore, gold ore, lead zinc ore, granite, basalt, diabase, limestone, dolomite, river pebble, quartz and other materials. It is applicable to mineral processing plants, sand and aggregate production lines, cement plant raw material crushing workshops and construction waste recycling facilities.

In mineral processing plants, cone crushers are often used in the secondary and tertiary crushing stages. The cavity design and wear resistance of mantle and concave liners directly affect the product size and the efficiency of downstream grinding operations. In sand and aggregate production lines, cone crushers are mainly used for shaping and sand making of hard rock materials. The wear resistance and cavity stability of liners have an important influence on the particle shape and grading of finished aggregates. In cement plant raw material crushing workshops, cone crushers are used for secondary and tertiary crushing of limestone and other raw materials, requiring liners with good wear resistance and impact toughness. Different applications have different requirements for liner material and cavity profile, and targeted selection and custom production can be carried out according to actual working conditions.

Production and Quality Inspection

Products are melted in medium frequency furnaces, with chemical composition precisely controlled according to material requirements. Raw materials are inspected for composition upon arrival to ensure alloying elements and trace elements meet standard requirements. During melting, the molten steel or iron is adjusted for composition and controlled for temperature to ensure pouring quality. After pouring and forming, products undergo standardized heat treatment processes including quenching, tempering and water toughening treatment to optimize the metallographic structure and mechanical properties. High manganese steel liners after water toughening treatment have excellent work hardening capacity. The surface can rapidly harden under impact and extrusion to form a high hardness wear resistant layer, while the core maintains good toughness. High chrome cast iron liners after quenching and tempering treatment have high hardness and wear resistance, suitable for strongly abrasive working conditions. Alloy steel liners obtain good strength and toughness matching through quenching and tempering treatment. Ductile iron liners obtain good comprehensive mechanical properties after heat treatment.

Quality inspection covers the entire process from raw materials to finished products, ensuring dimensional accuracy, internal quality and performance indicators meet requirements. Raw materials are inspected for composition upon arrival to verify chemical composition meets standards. Hardness testing is carried out during production to verify the hardness distribution of the surface and core of liners meets technical requirements, ensuring reasonable depth of the wear resistant layer and hardness gradient. Finished products are inspected by 3D scanning for dimensions and geometric tolerances to ensure assembly accuracy and fit of mating surfaces with the crusher. Internal defect inspection uses MT magnetic particle testing and UT ultrasonic testing to detect surface and internal defects such as cracks, porosity, slag inclusion and shrinkage, ensuring product safety under alternating and impact loads. Metallographic analysis is also carried out to observe grain size, carbide morphology, matrix structure and graphite spheroidization rate, evaluating wear resistance, toughness and structural uniformity of materials. Dimensional inspection covers key mounting dimensions, mating surfaces, conical surfaces and threaded holes to ensure products can be installed smoothly and run stably. Material reports, inspection reports and certificates can be provided according to customer requirements.
