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.
The cone crusher concave plate, also known as the cone crusher bowl liner, is fixed at the upper part of the crushing chamber. It serves as a wear-resistant liner to protect the upper accessories of the cone crusher. Together with the mantle for cone crusher, it forms the crushing chamber and comes into direct contact with the material.
the advantages of the crusher mantle and crusher bowl liner?
The bowl liner and mantle in a cone crusher enhance the efficiency and durability of the crushing process. They are used in various industries, including mining, construction, and road building.
Efficient Crushing
The cone crusher bowl and mantle compress and break down materials, achieving efficient and precise crushing.
Durability
The liners protect the cone head and components from wear, thereby extending the equipment's lifespan.
Easy Maintenance
The liners are replaceable, reducing downtime and simplifying maintenance.
Consistent Output
The stable and mobile parts of a cone crusher provide reliable and high-quality output.
High Wear Resistance
The liners are made from high-quality materials with excellent wear resistance and long service life.
Increased Capacity
The liners can be designed to allow oversized rocks to pass through the chamber, thereby increasing capacity.
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.
As the mantle liner moves, it crushes the material against the concave at the point where the gap is smallest (the stones in the feed also compress against each other--this is known as inter-particle crushing). Once the feed is crushed, it falls and exits the crusher through the space at the bottom.
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.
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
Maintenance tips of Concave and Mantle for Cone Crusher include:
● Regular Inspections: Conduct weekly inspections, including a thorough check of the Cone Mantle Concave and Bowl Liners.
● Adjusting the Closed-Side Setting (CSS): The CSS is the distance between the bottom of the mantle and the concave at the crusher's discharge point. Adjusting the CSS helps control product size and shape.
● Selecting the Correct Liner Profile: The shape and design of the crushing surfaces of the Moving and Fixed Cone Liners impact efficiency.
● Maintaining Bearings: Inspect the lubrication, temperature, and seals of the bearings.
● Checking Instruments: Ensure that instruments are functioning correctly and that oil pressure is accurate.
● Inspecting Pinion Shaft Lubrication: Regularly check the lubrication of the pinion shaft.
● Checking Gear Clearance and Seals: Regularly inspect gear clearance and seals.
● Documenting Wear Patterns: Record any wear patterns and their impact on production.
● Replacing Worn Components: Replace worn cone crusher mantle parts and bowl liner for cone crusher.
It is crucial to avoid combining new and worn components, as this can alter the crushing chamber profile and reduce productivity.

FAQ
Q: What are the wear parts of a cone crusher?
A: Cone crusher wearing parts include crushing wall, cast concave, main shaft and cone bushing, thrust plate and gear, frame and spherical bearing, eccentric bushing and straight bushing, bushing, taper bushing, etc. Consumable parts need to be replaced periodically.
Q: What are the main parts of a cone crusher?
A: The main components of a cone crusher include the main shaft, mantle, concave, cone, eccentric bushing, drive, crown gear, frame, and tramp release mechanism (mechanically or hydraulically actuated).
Q: What is the material of cone crusher mantle?
A: Austenitic Manganese Steel is the industry standard material for cone crusher liners.
Q: What material is used in crusher liners?
A: Manganese steel
Manganese steel has been used in crusher wear parts for decades because of its work-hardening properties. As rocks meet the surface of the manganese steel its exterior layer hardens. This results in a material that is harder to wear down during operation and can handle higher impact blows compared to other alloys.
Q: What is mantle in a crusher?
A: A mantle is a moving part in a cone crusher that crushes material by swinging against a stationary concave liner. The mantle and concave form the working surfaces of the crusher.
Q: How to avoid rapid damage to cone crusher parts?
A: The operator should master the correct cone crusher operation skills. Maintain the uniformity of the feed particle size and prevent special hard materials such as iron from entering the crusher and causing damage to the cone crusher's wearing parts.
Q: How to customize cone crusher parts?
A: Request a Custom Quote
Speak directly with a product expert to receive a tailored quote for parts that suit your specific crushing needs.

Q: How to choose cone crusher liners?
A: When choosing a cone crusher liner, you should consider the feed, the material being crushed, and the liner's manganese content.
Q: How to minimize equipment downtime when replacing the wear liners?
A: 1.Remove the eccentric sleeve and grind the worn areas of the straight and conical bushings to ensure the smoothness of the friction surfaces.
2.Before replacing the lower copper bushing of the moving cone and the eccentric sleeve bushing, check whether the inner diameters of the moving cone and the eccentric sleeve meet the standard requirements, and then install the new bushings.
3.When installing a new copper bushing, first cool the new copper bushing with dry ice or liquid nitrogen for at least 2 hours, then freely install it into the cone body and eccentric sleeve. Do not use hammering or pressing methods for installation.
4.Before installing the moving cone assembly and eccentric sleeve assembly, clean the outer wall of the eccentric sleeve and the spindle. After replacement, proper bedding-in must be performed according to operating procedures.
5.Adjust the tooth gap and side gap of the crusher’s large and small bevel gears. The gear gap can be adjusted by adding or removing shims under the thrust bearing.
6.Clean the horizontal shaft blower filter to prevent the filter from clogging or dust from entering the crusher, which could contaminate the lubrication oil.
7.Check whether the temperature sensors, pressure sensors, tooth counters, material level sensors, and hydraulic station button box are functioning properly. If damaged, they need to be replaced.
However, when assembling the cone crusher’s moving cone liner, first tighten the moving cone head to create preload with the spindle threads. After fastening the liner, secure it with the locking gear, and then pour zinc to cushion the impact of the liner on the equipment, preventing the liner from cracking.
Q: What is the difference between the fixed concave surface and the lower moving cone cover of the crusher?
A: In a cone crusher, the "fixed concave surface" refers to the stationary, bowl-shaped liner that forms the inner wall of the crushing chamber, while the "lower moving cone cover" is the bottom part of the rotating mantle (also called the "head"), which moves eccentrically within the concave, creating the crushing action by alternately closing and opening the gap between the two surfaces as it rotates; essentially, the concave is the fixed part, and the moving cone cover is the part that actively crushes the material by moving closer and further away from the concave.
Q: What is a crusher mantle?
A: The mantle is a moving part that gyrates in an eccentric motion. That is, it doesn't remain completely centred – it swings slightly as it rotates, continually altering the gap between the mantle and the concave (the ring outside the mantle that stays fixed in place.)
Q: What is a bowl liner?
A: The bowl liner, also known as concave, is the sacrificial wear liner that sets inside the upper frame to protect the upper accessories of the cone crusher.
Q: What is the Nip angle?
A: The nip angle is the angle between the mantle and bowl liner. Too large a nip angle reduces the capacity and increases the wear as feed material will tend to slip back upward in the cavity rather than crush. This can be observed as bouncing or boiling of the feed material.
Q: What is a cone liner?
A: A "cone liner" is a replaceable, bowl-shaped lining plate within a cone crusher machine, primarily used in mining and aggregate processing, that acts as the main wear part by protecting the crushing chamber from the impact of rocks being crushed, typically made from high-quality manganese steel to withstand heavy abrasion; essentially, it's the inner lining of the crushing cone in a cone crusher.
Q: What is a cone crusher liner?
A: A "cone crusher liner" is a replaceable wear part within a cone crusher, typically made from high manganese steel, that lines the crushing chamber and directly contacts the material being crushed, essentially acting as the surface that crushes rocks by compressing them between the moving "mantle" liner and the stationary "bowl" liner; it is considered the primary wearing component of a cone crusher.
Q: What material is used for cone crusher liners?
A: Cone crusher liners are typically made from manganese steel due to its excellent work-hardening properties, which means the material becomes harder as it is impacted by rocks, making it highly resistant to wear and tear in crushing applications; this is considered the industry standard for cone crusher liners.
Q: What are cone crusher liners made of?
A: Cone crusher liners are made from manganese steel, a material that hardens as it wears. The most common grades of manganese steel used for cone crusher liners are Mn13, Mn18, and Mn22.
Q: How do cone crusher mantle and concave components affect crushing efficiency?
A: In a cone crusher, the mantle and concave components directly impact crushing efficiency by defining the crushing chamber's size and shape, which determines the force applied to the material being crushed; a proper fit between these parts ensures optimal crushing action, while a poor fit or worn-out components can significantly reduce efficiency by causing uneven crushing, increased wear, and potential material jamming.
Q: What are cone crusher parts?
A: The main parts of a cone crusher include the frame, main shaft, mantle, concave, and drive. Other parts include the bearings, bowl liners, and tramp release mechanism.
Q: What is the hs code for crusher parts?
A: The HS code for crusher parts is typically 84749000. This code refers to "Parts of machinery for working mineral substances of heading 8474, n.e.s" which encompasses various crusher components likemn18cr2 concave and mantle, jaw plates, grinding discs, and other spare parts.
