Cone crushers are critical equipment in sand and aggregate production lines, widely used in secondary and tertiary crushing stages. High-quality spare parts from China ensure optimal performance, extended service life, and reduced downtime. Key components include:
– Concave & Mantle: Made from high manganese steel (Mn14Cr2/Mn18Cr2) for wear resistance.
– Eccentric Bushing: Precision-machined bronze bushings for smooth operation.
– Hydraulic Cylinder: Ensures adjustment of discharge opening and overload protection.
A standard 200TPH granite crushing line may include:
1. Primary Jaw Crusher (PE600×900) – Coarse crushing.
2. Secondary Cone Crusher (PYB1750) – Medium/fine crushing.
3. Tertiary Impact Crusher (VSI1140) – Shaping for high-quality sand.
4. Vibrating Screens (3YK2160) – Grading into 0-5mm, 5-10mm, 10-20mm aggregates.
| Part Name | Material | Hardness (HRC) | Lifespan (Hours) |
|———–|———-|—————|——————|
| Concave | Mn18Cr2 | 58-62 | 800-1,200 |
| Mantle | Mn14Cr2 | 55-60 | 700-1,000 |

Q: How often should cone crusher liners be replaced?
A: Depending on abrasiveness of material, typically every 800-1,200 hours for granite applications.
Q: Can Chinese spare parts match OEM quality?
A: Yes, reputable manufacturers use identical materials and heat treatment processes to OEM standards.
Project: Limestone Crushing Plant in Vietnam (500TPH)
Equipment: HP300 cone crusher with Chinese spare parts replacement after 18 months.
