Swing Jaw Plate 600/3012 For A Pegson 1100 × 800 In Liberia
600/3012 swing jaw plate in Mn22Cr2, supplied to a crushing contractor in liberia.
What The Customer Was Dealing With
A Pegson 1100 × 800 jaw crusher working in West Africa needed swing jaw plates on a feed abrasive enough that a general-purpose manganese die was not going to last.
Customer Pain Points
- Abrasive feed consuming standard manganese dies quickly
- A remote site where a second delivery is expensive and slow
- The need for a die that seats correctly first time, with no on-site fettling
What We Did About It
We cast the swing jaw to part number 600/3012 in Mn22Cr2 — 21-23% manganese with 1.5-2.5% chromium — so the crushing face work hardens further before it deforms. The pattern was already held, so no pattern lead time was added to the order.
How The Order Ran Through The Works
Pattern taken from inventory, no pattern-making stage
Bottom-poured from a 5 t intermediate frequency furnace
Sample taken during melting to verify the Mn22Cr2 analysis
Quenched within 30 seconds of furnace withdrawal
Back face and bolt holes machined, dimensional report issued
Packed on a steel pallet for sea freight to West Africa
What Was Delivered
The plate was supplied to the customer in Liberia under part number 600/3012 in Mn22Cr2, packed to international standard for the sea journey.
Customer Benefit
A higher manganese and chromium grade on a remote site means fewer change-outs and fewer deliveries, which on a West African contract is where the real cost sits.
Quality Control
Chemical analysis was carried out on the heat and the sample retained for at least three years. A dimensional inspection report was issued after machining and before packing.
