About the Powerscreen / Finlay / Pegson
Mobile and track-mounted units put the crusher on site, which means the wear parts have to be changed from a service platform rather than a workshop. Liner weight, lifting points and handling therefore matter as much as wear life.
This family covers the jaw, cone and impact chambers used on mobile plants, so the same casting and metallurgy experience applies — only the handling is different.
Wear parts we supply for the Powerscreen / Finlay / Pegson
- Fixed and swing jaw plates for mobile jaw units — Mn13Cr2 · Mn18Cr2
- Bowl liner and mantle for mobile cone units — Mn18Cr2 · Mn22Cr2
- Blow bars and impact plates for mobile impactors — Cr26 · Mn13Cr2
- Scraper plates, cheek plates, side liners — Mn13Cr2
- Wedge and clamping systems — mild steel / Mn13Cr2
- Compact sections to keep handling weight down — cast to drawing
Casting materials
| Material | Character | Typical use |
|---|---|---|
| Mn13Cr2 | Work-hardening manganese, good toughness | General quarry and recycling duty, cheek plates, chamber liners |
| Mn18Cr2 | Higher manganese, better resistance to heavy impact | Primary jaws, cone liners on coarse feed, gyratory mantles |
| Mn22Cr2 | Highest toughness of the manganese range | Large primary liners where impact is severe |
| Cr26 / Cr20 (high chrome) | High abrasion resistance, lower toughness | Blow bars, VSI tips and anvils, fine-crushing chambers |
| Bronze | Bearing grade, machined | Eccentric bushings, socket liners, thrust and step washers |
Material is chosen from the feed size, the rock type and the amount of uncrushable material in the stream — tell us how the current liners fail (worn out, cracked, or deformed) and we will match the grade.
How to order
- Send the machine model and part number, or your own drawing, measured sample or photos with dimensions.
- We confirm the profile, material and weight, then quote — FOB Ningbo or Shanghai for sea freight, with an air option for urgent stops.
- Patterns: a large pattern library is already on hand; where there is no pattern we make one (3D-printed pattern with a machined mould).
- Pouring, heat treatment and machining are carried out in our own foundry, then the parts are inspected against the drawing before packing.
FAQ
Can the liner be cast in a lighter section for mobile use?
Where the drawing allows, yes — sections can be kept to the minimum that still gives full service life, which makes manual liner changes in the field practical.
Do you supply wear parts for both the jaw and the cone on the same machine?
Yes. A mobile train with a jaw unit and a cone unit can be supplied from one order, with the liner profiles matched to each machine.
How fast can a replacement set be shipped?
Lead time is quoted per order and depends on whether we already hold the pattern. For critical stops we can also confirm air freight in the offer.
