What are the Concave and Mantle?
The cone crusher concave and cone mantle are components of a cone crusher used for crushing materials such as rocks and ores. The concave is fixed, while the mantle moves along the axis of the concave.
Crusher Concave
The concave, also known as the bowl liner, is the fixed part of the cone crusher's crushing chamber. The cone crusher upper mantle protects the upper accessories of the machine.
Crusher Mantle
The mantle is the movable part of the cone crusher's crushing chamber. It covers the cone head and protects it from wear. It acts as a sacrificial wear resistant lining.
Mantle & Concave: Technical Guide for Buyers
Working Principle of the Mantle and Concave
The mantle cone and concave are components of the cone crusher that work together to compress and crush materials. The mantle cone is a vibrating moving part, while the crusher concave is a stationary ring.
How it works
Fragile materials are fed into the cone crusher.
The cone crusher mantle moves in an eccentric motion, meaning it slightly oscillates as it rotates.
The moving cone compresses the material toward the bowl at the point where the gap is smallest.
The material is forced toward the bottom of the chamber.
As the material moves downward, it is repeatedly compressed and crushed.
Once the material is crushed to the desired size, it exits the crusher.
Material of the Fixed and Movable cone liner plate
The fixed cone liner plate and movable cone liner plate of a cone crusher are typically made from high-manganese steel, such as Mn13, Mn13Cr2, Mn18, Mn18Cr2, or Mn22Cr2, which is a material that can work-harden. They may also be made from other materials, such as modified high-manganese steel, manganese-chromium alloys, or advanced composite materials.
Surface Treatment
Galvanizing: The mantle and concave can be galvanized.
Polishing: The crusher concave and mantle can be polished.
Duma also supplies TiC insert mantles and concaves for extreme-abrasion applications. View TiC parts →
Production Process of the Mantle Concave
Cone crusher parts are widely used in various industries due to their high strength, good wear resistance, and durability. The production process of high manganese steel casting parts is complex and involves several stages. Below is a detailed description of the production process for manganese steel castings:
Application of Mantle and Bowl Liner
Application: Widely used in the mining industry, metallurgical industry, construction industry, chemical industry, and silicate industry for crushing hard and medium-hard ores and rocks, such as iron ore, limestone, copper ore, sandstone, etc.
Factors to Consider When Selecting a Concave Mantle
When choosing a concave mantle for cone crusher, factors such as feed material, eccentric throw, and closed-side setting (CSS) should be taken into consideration. These factors determine the product size, the rate at which material passes through the crusher, and energy consumption.
Feed Material
The size distribution of the raw material entering the crusher
The range of screens used to classify the feed
Sampling of the feed throughout the crushing process
Eccentric Throw
The distance the mantle moves away from the center of the crushing chamber
The speed at which material passes through the crusher
The range of motion of the high manganese cone mantles
Closed-Side Setting (CSS)
The narrowest gap between the cone crusher mantle liner and concave
The final crushing zone
The minimum possible product size output
Other Factors
Open-Side Setting (OSS), which is the maximum gap between the Cone Crusher Mantle&Concave
Machine reliability
Power consumption
Wear condition of the crushing chamber

Q: What crusher brands do your cone wear parts fit?
A: We supply direct-fit replacements for Metso (HP200, HP300, HP400, GP300, GP500), Sandvik (CH420, CH430, CH440, CH660, CS420, CS430), Terex, Kleemann, Telsmith, Shanbao, and Liming. Over 4,000 patterns on file — confirm your model and we verify fit before order.
Q: What manganese grades do you offer, and how do I choose?
A: Standard grades are Mn13, Mn13Cr2, Mn18, Mn18Cr2, and Mn22Cr2. For high-impact, softer rock: Mn13 or Mn18. For extreme abrasion or hard rock: Mn22 or TiC insert liners. Share your ore type and we recommend the right grade.
Q: Do you offer TiC insert mantles and concaves?
A: Yes. TiC (titanium carbide) insert liners are available for extreme-abrasion applications where standard manganese grades wear too fast. Lead time and pricing depend on size — contact us with your crusher model.
Q: What is your lead time?
A: Stock parts (HP200, HP300, HP400, GP300 standard profiles) ship within 7–10 days. Custom castings typically take 35–45 days from drawing confirmation.
Q: Do you accept trial or small orders?
A: Yes. We accept small trial orders for quality verification before committing to bulk supply.
Q: Can you produce parts from drawings or worn samples?
A: Yes. We support both drawing-based OEM production and reverse engineering from worn samples. Our engineering team can also take measurements if no drawings are available.
Q: What documentation comes with each order?
A: Every batch ships with a material certificate, dimensional inspection report, heat treatment curve, and metallographic report. Full traceability by batch.
Q: How do I confirm the part will fit my crusher without buying first?
A: Send us your crusher model, serial number, and any reference part numbers. We cross-reference against our pattern library and confirm fit in writing before you place the order.
Q: How do I choose the right liner profile (coarse / medium / fine)?
A: Profile selection depends on your feed size, closed-side setting (CSS), and target output gradation. Share your feed specs and we recommend the correct cavity profile.
Q: How do I avoid rapid wear or early liner failure?
A: Main causes are incorrect CSS, oversized feed, uneven feed distribution, and iron contamination. Ensure feed is within the crusher's rated size, maintain consistent choke feeding, and remove tramp metal upstream.
Q: How do I minimize downtime when replacing liners?
A: Key steps: cool new copper bushings with dry ice before installation (do not hammer), clean all mating surfaces, verify CSS after installation, and bed-in at reduced load for the first few hours. Avoid mixing new and worn components in the same chamber.
Q: What is the HS code for cone crusher wear parts?
A: The standard HS code is 84749000, covering parts of machinery for working mineral substances.
Q: What is your MOQ for bulk orders?
A: No fixed MOQ for standard parts. For custom profiles, MOQ depends on pattern tooling cost — we will advise at quotation stage.
Q: Are you a trading company or a factory?
A: Direct factory. We operate a 42,000 m² in-house facility covering casting, heat treatment, machining, and inspection. No third-party production.
Q: How quickly can you respond to a quote request?
A: Within 24 hours on business days. Provide your crusher model, part name, quantity, and any drawings or photos for the fastest response.
