Cone Crusher Replacement Parts

Jiangxi Duma Machinery Manufacturing Co., Ltd. is one of the most credible manufacturers and suppliers of cone crusher replacement parts in China. Welcome to buy discount cone crusher replacement parts in stock here and get quotation from our factory. We also accept customized orders.

Stop sacrificing your tonnage to low-grade aftermarket liners. At Duma Machinery, we specialize in high-performance Mn18Cr2 and Mn22Cr2 mantles and bowl liners specifically engineered for Metso (HP & GP), Sandvik (CH & CS), and Symons crushers, providing reliable cone crusher replacement parts for demanding mining and quarry applications. Operating from our 42,000 m² integrated foundry, we bridge the gap between durable metallurgy and factory-direct pricing. During crusher operation, the mantle and concave move in a circular motion against the rock, causing wear over time, and Duma's replacement parts are precisely engineered to maintain the correct crushing chamber geometry and ensure optimal particle size control.

A "one-size-fits-all" liner is a myth. Duma's engineers analyze your feed material-whether it's abrasive basalt or tough iron ore-to recommend the perfect cavity configuration (Extra Coarse to Fine). Our precisely machined seating surfaces ensure a flush fit, eliminating the vibrations that cause premature fatigue in your crusher's head.

Duma Machinery's mantle and bowl liner sets are widely used in mining, quarrying, and aggregate production applications. They are suitable for crushing a variety of materials, including granite, basalt, limestone, and other hard or abrasive stones. Designed to perform under demanding working conditions, these liners ensure stable operation, consistent output size, and long service life across primary, secondary, and tertiary crushing stages. 

 

High-Performance Mantle & Bowl Liner - Durable, Precise, and Efficient

 

Duma Machinery's mantle and bowl liner sets deliver exceptional crushing performance through optimized design, premium alloy steel, and precise fit, making them ideal cone crusher replacement parts for demanding mining and aggregate operations. Manufactured from Mn13Cr2, Mn18Cr2, or Mn22Cr2, each liner provides a durable wear surface that ensures smooth material compression, consistent particle size, and reduced downtime. Fully interchangeable with OEM parts and available in customized cavity profiles, these replacement liners can extend wear life by up to 30%, offering a reliable and cost-efficient solution.

 

In-House Metallurgy: The Duma Quality Standard

 

 

 

Unlike trading companies, we control the production process of your wear parts in our 42,000 m² facility.

Water Toughening Process: We use digitally controlled furnaces to perform solution heat treatment, followed by high-power water quenching. This locks the structure into a 100% pure austenite state, eliminating the brittle carbide networks that cause other liners to crack.

Traceability: Every batch comes with a "Birth Certificate," including chemical composition analysis and Ultrasonic Testing (UT) reports.

Factory & Production

 

Our foundry is located near a major seaport, enabling fast and cost-effective export logistics. This strategic advantage helps reduce delivery time and lower shipping costs for global customers.

 

Duma integrates melting, sand casting, machining, and quality inspection in-house. Each cone crusher liner is tested before delivery, including chemical composition analysis, ultrasonic testing, and hardness inspection to ensure stable quality.

FAQ

 

Q: How to choose the right material for cone crusher liners?

A: The choice depends on feed hardness, size, and working conditions. For medium-hard materials, Mn13Cr2 is a cost-effective option, while for harder or highly abrasive ores, Mn18Cr2 or Mn22Cr2 provides superior wear resistance.

Q: How much longer will Duma liners last compared to standard aftermarket parts?

A: Based on field feedback from quarries in Russia and South Africa, our Mn22Cr2 with TiC reinforcement liners typically deliver a 20%–40% increase in service life. This is achieved through a dynamic work-hardening process, where surface hardness increases from HB200 to over HB500 under impact conditions.

Q:Can Duma liners be used on other cone crusher brands?

A: Yes. Duma manufactures replacement liners that are compatible with major brands such as Metso, Sandvik, Terex, and Telsmith. Customization of cavity shape, thickness, and material is also available upon request.

Q: How do I know when it is time to replace the liners?

A: When liner thickness is reduced by more than 70%, or the discharge size becomes unstable, replacement is required. Regular inspection helps ensure consistent crushing performance.

Q: What kind of after-sales support does Duma provide?

A: Duma provides full technical guidance, wear analysis, and liner optimization recommendations based on your actual operating conditions. On-site or remote support is available to ensure efficient operation.
