Manganese Steel Castings
Cone Crusher Mantles and Bowl Liners
Mantles and bowl liners set the crushing chamber profile. Get the alloy, the fit and the backing right and the chamber wears evenly instead of tearing itself apart.
- Mantles, bowl liners, check plates and wear plates
- Produced to drawing or to a sample of the worn part
- Written specification for melting, pouring and heat treatment
- Matching sets supplied together so the profile stays true
Product Overview
About This Programme
Typical products are cones, check plates, wear plates and others. We supply standard OEM style products and we supply parts that match most machine types on the market.
A cone chamber is a matched pair. If the mantle and the bowl liner wear at different rates, the closed side setting drifts, the product gradation changes and the crusher starts drawing uneven power. That is why we prefer to quote and ship them as a set rather than as two separate line items.
Key Benefits
Key Benefits
Why buyers move this part to us, in their words rather than ours.
Even chamber wear
Mantle and liner cast from the same specification and shipped as a matched set, so the profile stays true through the wear life.
Work hardening under load
Austenitic manganese steel hardens at the working face while the core stays tough, which is what a cone chamber needs under continuous impact.
Repeatable batches
Melting chemistry, pouring temperature and the heat treatment cycle are fixed in a written specification, so batch two matches batch one.
Application Scenarios
Application Scenarios
- Primary and secondary cone crushers in hard rock quarrying
- Gyratory and cone chambers in metal ore processing
- Aggregate plants producing to a fixed gradation
- Mobile crushing spreads where a chamber change stops production
Who It Is For
Who It Is For
Quarry maintenance teams
Ordering chamber sets on a planned change out interval.
Mining contractors
Running hard, abrasive feed where chamber life decides the cost per tonne.
Crusher dealers and service shops
Reordering repeat batches against tooling we already hold.
Problems It Solves
Problems It Solves
If one of these is happening on your plant, send us the part and the current life figures.
- Mantle and liner wearing at different rates and pulling the setting out
- Backing compound failing because the liner seat is not true
- Liners that crack across the section instead of wearing evenly
- Hardness that varies from piece to piece within a delivery
- Lead time on a chamber set that leaves the crusher standing
Technical Features
Technical Features and Materials
Alloy
Austenitic manganese steel, grade agreed against the duty and the feed material.
Geometry
Cast to your drawing or reverse engineered from a worn sample with the seat and bolt geometry checked.
Heat treatment
Solution treatment and water quench cycle controlled to a written specification.
Inspection
Composition by spectrometer, hardness on every batch, dimensions against drawing or master sample.
Manufacturing Process
Manufacturing Process
The moulding route is chosen for the part. It is confirmed in writing with the quotation, together with the tolerance class and the machining allowance.
| Process | Best Suited For | Tolerance | Piece Weight |
|---|---|---|---|
| Green sand process | Small and medium parts with low dimensional requirement | CT11–CT14 | 0.2–200 kg |
| Resin sand process | Medium and large parts with high dimensional requirement | CT10–CT11 | 100–3000 kg |
| Shell molding process | Small and medium parts with strict dimensional requirement | CT7–CT9 | ≤50 kg |
| Lost foam process | Small and medium parts with complex structure | CT7–CT9 | ≤100 kg |
| Vacuum process | Medium and large parts needing good surface roughness | CT7–CT9 | ≤10000 kg |
Quality Control
Quality Control and Certification
Inspection is planned at the stages where a problem is still cheap to fix.
- Chemical composition by optical emission and handheld spectrometer
- Hardness tested and reported on every batch
- Dimensions checked against your drawing or the master sample
- Non destructive testing by magnetic particle, penetrant or ultrasonic method where the drawing requires it
Certification documents are issued by the producing factory for the specific order. Ask for the certificate package that applies to your part before you place the order.
Customization
Customization Options
Material and grade
Any grade in the programme, or a grade you nominate with the local equivalent confirmed before production.
Geometry and fixing

Part number marking, position marking for sets, and export packing agreed before production.
Use Guide
How to Order
STEP 01
Send the drawing or the worn part
A drawing, a 3D file, or photographs with overall dimensions and the machine details. Add the annual quantity.
STEP 02
Confirm material and construction
We propose the grade and, where relevant, the construction, and explain the trade off against your current part.
STEP 03
First article
Tooling is made and the first article is measured and tested before the batch is released.
STEP 04
Batch and inspection
Stage inspections during production and a final inspection to the agreed standard with the reports you need.
STEP 05
Packing and shipment
Export packing marked with your part numbers, with the shipping documents you require.
