Sandvik CH and CS Cone Crusher Parts: Compatibility Guide

Why Part Compatibility Matters

Sandvik cone crushers, especially the CH and CS series—are widely used in mining and aggregate production worldwide. From the compact CH420 to the large CH880, they handle demanding crushing duties in copper, iron ore, gold and aggregate operations. When wear parts need replacement, maintenance teams must assess machine identification, part numbers, chamber profiles, materials, quality documents, lead times and site validation.

Part compatibility affects fit, chamber geometry, capacity, energy use, wear and downtime risk. Its impact varies by machine and operating conditions. This guide provides a framework forSandvik crusher parts identification, cross-referencing and quality verification. Final fit must be confirmed from the equipment nameplate, serial number, original part number, current drawings and manufacturer documentation.

Sandvik CH Series Overview

The Sandvik CH series comprises hydraulic cone crushers for secondary, tertiary and quaternary crushing. Interparticle compression produces a good particle shape and high reduction ratio. CH models share Sandvik's patented design principles but differ in throughput, feed size and power requirements.

The CH series uses Sandvik's chamber optimization system. Changing the mantle and concave combination allows selection of extra-coarse, coarse, medium or fine chambers. This supports different crushing stages, but replacement orders must specify the correct chamber profile.

Sandvik CS Series Overview

The Sandvik CS series is designed for secondary crushing where high throughput and consistent product quality are required. A steeper head angle and optimized eccentric throw distinguish CS from CH, suiting high-output mining circuits after a primary gyratory or jaw crusher.

CS wear parts are not interchangeable with similarly sized CH parts. The CS430 and CH430 mantles differ in profile geometry and eccentric-bushing compatibility. Confirm whether the machine is CH or CS before ordering replacement wear parts.

CS and CH model names can look similar, such as CH430 and CS430, but their internal geometry, eccentric bushings and chambers differ. Never assume interchangeability between series.

Key Sandvik Cone Crusher Wear Parts

Sandvik cone crushers contain several critical wear components. Effective maintenance planning requires an understanding of each part's function, wear pattern and replacement criteria.

Mantle (moving-cone liner)

The mantle is the conical liner covering the main-shaft head. As the eccentric assembly rotates, it gyrates relative to the concave to compress the feed. Mantles typically account for 40–50% of wear-part costs and are replaced frequently. Wear concentrates in the parallel zone, where compression is greatest.

Concave (fixed-cone liner)

The concave is the fixed liner in the upper crusher shell or bowl. Together with the mantle it forms the crushing chamber. Its wear is generally more uniform than mantle wear, although the lower section near the parallel zone wears fastest. Most Sandvik concaves use a segmented design to simplify handling and installation.

Eccentric bushing

The eccentric bushing contributes to the head's gyratory motion. Its material and construction vary by model, and fit and lubrication requirements are strict. Wear can cause abnormal motion, uneven liner wear or changes in product size. Set inspection and replacement intervals from the machine manual, clearance measurements and oil-analysis trends.

Spider bushing

The spider bushing, also described here as the upper eccentric bushing, guides the main shaft at the top of the crusher. It carries lower stresses than the main eccentric bushing but still requires monitoring. Excessive clearance permits shaft movement, accelerates mantle and concave wear and can damage the spider assembly.

Dust seal ring

The dust seal ring keeps abrasive dust and contaminants out of the crusher, particularly the eccentric and drive-shaft bearings. Damage allows dust into the lubricating oil and can rapidly damage bearings. Inspect the ring at every liner change and replace it when lip wear exceeds 50%.

Material Selection

Material grade is a major factor in Sandvik mantle and concave performance. The three grades below are austenitic high-manganese steels that undergo work hardening under impact, forming a hard surface while retaining a tough, ductile core. For more information on High-manganese steel properties, see the material reference page.

Mn13Cr2 (standard manganese steel)

Mn13Cr2 is a standard manganese steel containing 11–14% manganese. Under suitable impact conditions, its surface work-hardens to 500+ HBW. It is best suited to moderately abrasive duties:

• Secondary crushing with feed larger than 50mm
• Moderately abrasive ore (abrasion index A_i 0.3–0.5)
• Typical aggregate duties on CH420 and CH430
• Duties prioritizing impact toughness over maximum wear resistance

Mn18Cr2 (high-manganese steel)

Mn18Cr2 contains 17–19% manganese and extends wear life by 20–40% over Mn13Cr2 under equivalent conditions. Its stronger work-hardening response can reach 550+ HBW. Recommended duties include:

• Highly abrasive ore (A_i 0.5–0.8)
• Hard-rock crushing: granite, basalt and quartzite
• Abrasive-material duties on CH440, CH660 and CS440
• Duties where fewer changes justify the material premium

Mn22Cr2 (ultra-high-manganese steel)

Mn22Cr2 is the highest-manganese grade in this comparison, containing 21–23% manganese and reaching a surface hardness of 580+ HBW. It is used for the most demanding duties:

• Extremely abrasive ore (A_i > 0.8)
• Large CH870, CH880 and CS660 machines in hard-rock mines
• Copper, gold and iron ore duties requiring maximum liner life
• High-throughput lines with very high unplanned-downtime costs

Part-Number Cross-Reference Guide

Identifying the correct Sandvik part number is the first step in sourcing a compatible replacement. Sandvik assigns proprietary references to wear components; these are a key basis for checking dimensional compatibility. Use the following identification and cross-reference methods:

How to Find a Part Number

1. Inspect the part— Sandvik marks part numbers on non-wearing mantle and concave surfaces. Clean the surface and look for laser-etched or cast alphanumeric markings.
2. Check the crusher nameplate — The frame nameplate gives the model, such as CH430, helping narrow the part search.
3. Consult the operating manual— The spare-parts section contains exploded views and references for each component.
4. Contact Sandvik support— Provide the crusher serial number for an exact parts list; response times may vary.

Common Cross-References

The table lists representative Sandvik wear-part numbers as a starting point only. Confirm each against the specific crusher configuration and chamber profile.

Note: these are representative references. Sandvik periodically updates part numbers, and chamber profiles (EC/C/M/F) use different suffixes. Confirm the exact reference in the crusher documentation before ordering.

Quality Checks for Aftermarket Parts

Quality varies among aftermarket parts marketed for Sandvik crushers. Check the following criteria before ordering. Suppliers such as ANRANST should be able to provide the supporting documentation.

Dimensional Accuracy

Aftermarket mantles and concaves must match the approved drawings and chamber profile. Tolerances vary with the model, dimensional feature and inspection datum. List them individually in the procurement specification and dimensional report:

• Mantle inside diameter— Must match the head diameter for the correct fit
• Mantle cone angle— An incorrect angle causes uneven contact and accelerated local wear
• Concave outside diameter— Must seat correctly in the bowl without excessive clearance
• Thread pitch and profile— For threaded concave retaining rings
• Overall height and parallel-zone length— Determine crushing-chamber geometry

Request a dimensional inspection report, such as a CMM report, comparing measured values with nominal specifications. Treat unwillingness or inability to provide dimensional data as a concern.

Material Certification

Chemical composition directly affects wear performance. Request a chemical analysis certificateto confirm that composition meets the specified grade:

Check that phosphorus and sulfur remain below the limits: excessive levels cause embrittlement and premature liner failure. A qualified supplier provides a chemical analysis certificate for each heat.

Hardness Verification

Austenitic manganese steel in the supplied condition, before work hardening, should be within 200–240 HBW. Excessive hardness can indicate incomplete solution treatment and brittleness; insufficient hardness can indicate unsuitable heat treatment and poor wear performance. Request Brinell results from at least three locations on each part.

Heat Treatment

Austenitic manganese steel generally requires suitable solution treatment and rapid cooling, but temperature, holding time and transfer requirements depend on the grade, section size, applicable standard and qualified process. Buyers should check heat records, heat-treatment curves, hardness and metallography where required. A generic temperature range is not an acceptance criterion for every casting.
