Matched sets, not single pieces
The mantle and the concave (bowl liner) form the crushing chamber together. They wear together and must be replaced together. A new mantle running against a worn concave distorts the chamber geometry — throughput falls, the product turns flaky, and power draw climbs for no reason.
We supply mantle and concave only as matched sets, cast from the same heat where the profile demands it. No mixing, no shortcuts.
Chamber options
One crusher, several chambers. The chamber decides the feed size it accepts and the product shape it makes:
| Chamber | Feed opening | Product | Suited for |
|---|---|---|---|
| Coarse | Largest | Coarse aggregate | Secondary crushing directly after the jaw |
| Medium | Medium | Mid-size aggregate | General quarry production |
| Fine | Smaller | Finer aggregate | Tight product specifications |
| Extra fine | Smallest | Manufactured-sand feed | Sand-making lines |
Tell us your closed-side setting and target product — we recommend the chamber. The wrong chamber in the right crusher still makes the wrong product.
Materials
| Grade | Character | Use it for |
|---|---|---|
| Mn13 | Standard high-manganese; work-hardens in service | Medium-hard rock, general duty |
| Mn18 | Higher manganese; harder working surface | Hard, abrasive rock: granite, basalt |
Cone liners live in continuous abrasion rather than heavy impact, so Mn13 and Mn18 cover the range. We do not recommend high-chrome for cone chambers — the impact at the nip zone is enough to crack it.
Fit across cone types
- Symons / spring cone: 2 ft, 3 ft, 4¼ ft, 5½ ft and 7 ft — PYB, PYZ and PYD series.
- Single-cylinder hydraulic: common Chinese-built models; send the model number and we confirm the pattern.
- Multi-cylinder hydraulic: matched mantle and concave sets to your chamber code.
Send the crusher model plus the chamber designation (for example, "4¼ ft, fine chamber"). A correct-size liner in the wrong chamber profile will not seat properly.
What wears first
The concave usually wears faster than the mantle — it sees the full feed stream. Check the concave at two-thirds of the expected mantle life; replacing the concave once mid-cycle keeps the chamber geometry true and extends the mantle's useful life.
