1. Definition Sandvik crusher wear parts are replacement components designed to fit Sandvik crushing equipment – including CH Series and CS Series cone crushers, CJ Series jaw crushers, and QJ Series mobile crushers. Aftermarket manufacturers produce these parts to OEM dimensions. 2. Working Principle Sandvik cone crushers (CH/CS) use a gyrating mantle inside a concave. Material is crushed by compression. Sandvik jaw crushers (CJ) use fixed and moving jaw plates. Manganese steel work-hardens under impact. 3. Benefits of Aftermarket Sandvik-Compatible Parts Cost reduction: 30–50% lower than Sandvik OEM Extended wear life: Mn22 can outlast Mn18 by 40–80% on abrasive ores Shorter lead time: 4–6 weeks typical Customization: Modify tooth and chamber profiles Obsolescence support: Older Sandvik models supported For cone crusher specific optimization, see <a href=”https://www.tufflexscreen.com/the-core-of-cone-crusher-performance:-mantle-and-concave-engineering.html”>Mantle and Concave Engineering</a>. 4.

Selection Guide for Sandvik-Compatible Suppliers Step 1 – Document your Sandvik crusher: Model (e.g., Sandvik CH440, CJ412) OEM part number (stamped on existing part) Step 2 – Characterize your ore: Abrasion index (Ai) Work index (Wi) Step 3 – Select Mn grade: Ai < 0.4 → Mn18 Ai > 0.6 → Mn22 Step 4 – Request trial set with material test reports. Step 5 – Monitor wear life and calculate cost per ton. 9. Procurement Guide for Sandvik-Compatible Parts Required information for quote: Sandvik crusher model and serial number OEM part number or drawing (PDF, DWG, STEP) Desired manganese grade (Mn13/18/22) Quantity (sets) Destination port Supplier evaluation checklist (score 1–5 each): Previous experience with Sandvik-compatible parts In-house foundry In-house heat treatment ISO 9001:2015 Spectrometer for chemical analysis Brinell hardness tester Dimensional inspection (CMM) Provides material test reports Can manufacture from drawing or sample Lead time ≤6 weeks Typical terms: MOQ: 1–5 sets Lead time: 4–6 weeks Packaging: Steel pallet or crate Shipping: FOB, CIF, EXW 10. Failure Analysis – Sandvik-Compatible Parts Problem Observable Signs Possible Cause Solution Premature cracking Linear cracks on mantle/jaw plate Poor heat treatment Require certified heat treatment records Poor fit Difficult installation Inaccurate pattern Request dimensional inspection report Short wear life <500 hours life Wrong Mn grade for ore Upgrade from Mn18 to Mn22 Uneven wear on cone liners One side worn more Feed distribution issue Check feed chute and crusher setting 11. Maintenance Guide for Sandvik-Compatible Wear Parts Installation: Clean all mating surfaces Apply anti-seize on threads Torque to Sandvik specifications Weekly monitoring: Measure closed side setting (CSS) Record hours and tons crushed Photograph wear progression Cost tracking: Cost per ton = (part cost + labor) / tons crushed 12. Case Study – Gold Mine, Western Australia Customer Type: Mid-size gold mine, 500 t/h Operating Conditions: High-silica quartz ore, Ai=0.65, 16h/day Crusher: Sandvik CH440 cone crusher Original parts: Sandvik OEM Mn18 mantle and concave – 1,000 hours life Problem: Rapid wear on lower concaves, CSS drift every 250 hours, high cost per ton Solution: HUATAO Mn22 mantle and concave with modified chamber profile Result: Wear life increased to 1,550 hours (+55%) Cost per ton reduced by 30% Annual savings per crusher: ~$50,000 13.
