Cone crushers are the backbone of mining, quarrying, aggregate production, and rock crushing plants. To maintain stable output, reduce unplanned downtime, and extend machine service life, you must stock and understand the most essential cone crusher spare parts and wear components.
Whether you use Sandvik, Metso, Terex, Symons, or other mainstream cone crusher models, knowing these top 10 cone crusher spare parts helps you arrange maintenance, prepare inventory, and avoid production shutdown caused by sudden part damage.
Below we list the must-know cone crusher spare parts with functions, material options and replacement tips for your reference.
1. Mantle
The mantle is the rotating cone liner installed on the head center. It directly contacts raw rocks and undertakes most compression and impact crushing work.
Common materials: High manganese steel Mn13, Mn18Cr2, high abrasion alloy and carbide embedded liner.
It is the most frequently replaced wear part in cone crusher systems.
2. Bowl Liner (Concave)
Also named concave, the bowl liner is fixed inside the adjustment ring. It works together with the mantle to form the crushing chamber.
It controls final aggregate particle size and protects the main frame from severe wear. Custom chamber profiles (coarse, medium, fine) are available for different crushing requirements.
3. Head Liner & Torch Ring
The torch ring and head liner protect the upper feeding area from material impact and abrasion. They prevent premature wear of the main head assembly and stabilize feeding distribution. Ideal for heavy-duty quarry and mining conditions.
4. Main Shaft
The main shaft is the core load-bearing component that connects the head and eccentric assembly. It bears huge torque, impact force and bending pressure during operation. High-quality forging and strict heat treatment are required to avoid shaft fracture.
5. Eccentric Bushing & Socket Liner
Eccentric bushing and bronze socket liner support eccentric rotation and ensure stable running clearance.
Worn bushings will cause vibration, abnormal noise and uneven gear meshing. Regular inspection can greatly extend cone crusher service life.
6. Countershaft & Pinion Gear
The countershaft and pinion gear transmit engine power to the eccentric assembly. Precise gear tooth accuracy and wear resistance guarantee smooth power transmission. Damaged pinion gears will lead to serious equipment shutdown.
7. Adjustment Ring & Clamping Ring
The adjustment ring is used to adjust the closed side setting (CSS) and control discharging size. The clamping ring fixes the bowl liner tightly to prevent loosening during strong crushing impact.
8. Dust Seal & Dust Ring
Dust seal components prevent dust and fine sand from entering the lubrication system and bearing parts. Good dust sealing protects lubrication oil purity and reduces abrasion of internal precision parts.
9. Hydraulic Cylinder & Hydraulic Parts
For hydraulic cone crushers, hydraulic cylinders support overload protection, cavity clearing and gap adjustment. Seals, gaskets and hydraulic cylinder spare parts are essential for daily maintenance and fault handling.
10. Frame Arm Guard
Arm guards protect the main frame arm from material splashing and external impact. They are low-cost but important wearable parts to avoid frame deformation and damage.
