Cone Crusher Parts

Introduction

Cone crusher wearing parts are the sacrificial components that protect the crusher’s main structure while performing the actual rock-breaking work. They are subjected to extreme abrasive and impact forces during the crushing process and must be replaced periodically to ensure equipment integrity and optimal performance.

The two primary wearing parts in a cone crusher are the mantle (mounted on the moving cone head) and the bowl liner/concave (mounted in the upper frame). Together, they form the crushing chamber where material is compressed and reduced . Additional wear components protect other vulnerable areas of the crusher from premature failure.

Manufactured primarily from high-quality manganese steel with work-hardening properties, modern cone crusher wear parts are engineered to match specific crushing applications, delivering extended service life, reduced downtime, and lower cost per ton.

Working Principle

Cone crushers operate by compressing feed material between the mantle (moving crushing shell attached to the head) and the bowl liner/concave (stationary or adjustable crushing shell mounted in the frame).
Feed Entry: Material enters the crushing chamber from the top.

Compression Crushing: The mantle gyrates eccentrically within the concave. As it approaches the concave, the material is progressively crushed. When the mantle moves away, the crushed material descends by gravity. Gradation & Discharge: The narrowing gap towards the bottom ensures final sizing. Processed material exits through the bottom of the chamber.

The selection of appropriate wear parts—including chamber profile (Standard, Short Head, or specific concave/mantle combinations like EC, C, MC) and metallurgy—directly impacts efficiency, product shape, and wear life.

Applications

Cone crusher wear parts are critical across industries requiring high-capacity secondary, tertiary, or quaternary crushing of hard and abrasive materials:

• Mining:Crushing hard ores (iron ore, copper, gold, etc.).
• Aggregates & Quarrying:Producing crushed stone (granite, basalt, limestone) for construction.
• Recycling:Processing concrete and asphalt rubble.
• Industrial Minerals:Size reduction for chemical, cement, and refractory materials.

Features

Mantle (Head Liner)

The mantle is the moving wear part that covers the cone head. It works directly with the bowl liner to compress and crush material. Key considerations include:

• Materials: Premium manganese steel (Mn13Cr2, Mn18Cr2, Mn22Cr2) ; often featuring a concave profile to improve crushing efficiency .
• Lifting Tools: Specialized tools facilitate safer and easier maintenance .
• Accessories: The feed cone (distribution plate) should be replaced every time the mantle is changed .

Bowl Liner / Concave

The bowl liner is the stationary wear part fitted inside the upper frame. It comes in various profiles for specific applications .

• Chamber Profiles: Available as Extra Coarse (EC), Coarse (C) , and Medium Coarse (MC) for primary/secondary crushing, or Fine (F) for tertiary applications .
• Special Designs: Segment bowl liners (for larger crushers) reduce casting complexity and facilitate easier handling .

Additional Wearing Parts

To ensure complete protection and reliable operation, these ancillary parts should also be inspected and replaced when liners are changed :

• Main Frame Liners-Protect the crusher frame from material wear .
• Arm Guards-Shield the frame arms from abrasion .
• Feed Cone / Distribution Plate-Directs material evenly into the chamber; replaced with the mantle .
• Counterweight Liners-Protect the counterweight assembly from wear .
• Padding Material-Used as shock absorption during installation for certain models (e.g., HP200-HP500) to cushion the liner and prevent movement .

Material Options & Selection

Selection of the right material and chamber profile is critical for maximizing performance and minimizing cost per ton.

• Mn13Cr2-High impact resistance; standard work-hardening-General-purpose crushing .
• Mn18Cr2-Enhanced wear resistance-Highly abrasive materials .
• Mn22Cr2-Superior durability and work-hardening capability-Heavy-duty, extreme abrasion.
• Super Hard Inserts-PCD/CBN or cemented carbide tips embedded in liners, Ultra-abrasive applications to extend life significantly .
• Chamber Selection Factors: The optimal chamber (mantle + concave pairing) depends on feed size, desired product gradation, and the abrasiveness of the material. OEMs offer standardized choices (e.g., Sandvik's A, S, B mantles and EC, C, MC concaves) or customized solutions through simulation software.
