Buyer context
Who this guide is written for.
Quarry operators, mining maintenance teams, aggregate plants, crusher repair workshops, and distributors preparing jaw plate, cheek plate, liner, screen media, and wear protection RFQs.
A crusher wear part inquiry can look simple from the outside. The buyer may only write jaw plate, cheek plate, liner, or screen panel and attach a photo. In practice, the supplier still has to understand the machine model, installed position, wear face, fixing method, material route, and whether the part is being replaced alone or as part of a shutdown package.
The most expensive mistake is not always a broken part. It can be a part that almost fits, a hole pattern that is slightly wrong, a liner supplied without the right fixing detail, or a material proposal that cannot be judged because the operating condition was never described.
A useful RFQ does not need to be long, but it should be line based. Each item should show the part name, machine or drawing reference, dimensions, material expectation, quantity, photos of the worn part, and any deadline linked to planned maintenance.

Mismatch risks
Where quotes usually go wrong.
The jaw plate profile is treated as a generic item.
- Cause
- The RFQ gives only the crusher model or a worn photo without chamber position, profile, drawing, or old casting mark.
- Buyer loss
- The part may fit poorly, reduce crushing performance, or require urgent replacement during the next maintenance window.
- Control
- Send machine model, fixed or movable position, old part number if available, profile photo, main dimensions, and hole layout.
Material comparison is not meaningful.
- Cause
- Different suppliers quote different material routes, but the buyer only compares the final unit price.
- Buyer loss
- A low quote may not match the same wear expectation, impact condition, or heat-treatment route.
- Control
- State handled material, feed size, impact level, target material or hardness notes, and whether material certificates are required.
The liner fits the surface but not the fixing layout.
- Cause
- Photos show the wear face, while countersunk holes, bolt spacing, slot direction, or backing plate details are missing.
- Buyer loss
- Installation slows down, site drilling or cutting is needed, or the liner cannot be used during shutdown.
- Control
- Provide drawing, bolt pattern, hole type, plate thickness, bend direction if any, and photos of the installation face.
Screen media is quoted with the wrong aperture or fixing.
- Cause
- Panel size is sent, but aperture, open area, fixing rail, hook edge, deck position, and screening condition are not confirmed.
- Buyer loss
- Production output, grading accuracy, or panel life can be affected even when the panel size is close.
- Control
- Confirm aperture, panel size, fixing style, wet or dry screening, material handled, and current panel photos.
A mixed wear package has no shutdown priority.
- Cause
- Crusher parts, screen panels, hopper liners, and GET items are sent in one list without marking critical items.
- Buyer loss
- Suppliers spend time on low-risk items while the parts that stop production are not reviewed first.
- Control
- Mark urgent shutdown items, preferred shipment split, and whether partial delivery is acceptable.
RFQ fields
Information to put in the first email.
| Scope | Send | Why it matters |
|---|---|---|
| Crusher wear parts | Crusher model, fixed or movable position, old part number, drawing or measured dimensions, profile photos, and quantity. | Jaw plates and cheek plates need chamber and fit review before the quote can be compared properly. |
| Wear liners | Liner drawing, plate thickness, bolt pattern, installed position, handled material, impact condition, and photos of the worn area. | Liners fail as a system of material, geometry, fixing, and working condition, not as a plate name only. |
| Screen media | Panel size, aperture, fixing style, deck position, wet or dry use, material handled, and required quantity by panel type. | The same outside size can have different apertures, fastening details, and screening behavior. |
| Hopper and chute items | Drawings, plate layout, liner map, welding scope, lifting points, coating notes, and transport size limits. | Fabricated wear structures need fit, welding, packing, and site handling review. |
| Material and inspection | Target material, hardness or heat-treatment notes, inspection requirement, certificate request, and sample approval need. | Wear-part quotations can only be compared when the material and inspection scope are visible. |
| Commercial details | Quantity by item, urgent line items, destination port, packing requirement, partial shipment option, and deadline. | Shutdown work often needs staged delivery and packing review before lead time is confirmed. |
Review route
How this RFQ should be cleaned up.
- Separate crusher, screen, liner, and fabricated items.Do not ask for one price for a mixed wear list. Each line should have a part name, reference, drawing status, quantity, and urgency.
- Confirm fit before asking for material alternatives.A supplier can discuss material only after the chamber position, hole layout, liner fixing, or panel fastening detail is clear.
- Describe the actual wear condition.Feed size, abrasive material, impact point, moisture, and operating position explain why one material or liner route may be more suitable than another.
- Mark what must arrive first.For planned shutdowns, critical items should be reviewed before slow-moving or low-risk replacement parts.
- Lock the inspection and packing scope before order.Hardness checks, dimensional checks, part marks, pallet separation, and crate protection should be tied to the final item list.
Factory review points
Control points buyers should ask suppliers to check.
- Crusher model, chamber position, old part number, and drawing revision confirmation.
- Jaw plate profile, hole layout, casting mark, and main dimension review.
- Wear liner plate thickness, bolt pattern, backing face, and installed orientation check.
- Screen panel aperture, outside size, fixing method, and deck position confirmation.
- Material route, hardness or heat-treatment checkpoints where required.
- Item marks, mixed-package separation, pallet protection, and urgent-line packing plan.
FAQ
Common questions before sending this inquiry.
Can crusher wear parts be quoted from a machine model only?
The machine model helps, but it is usually not enough. The supplier still needs position, old part number or drawing, photos, dimensions, and quantity before confirming the correct route.
Should material be specified in the first RFQ?
Yes, if the buyer has a target material or hardness requirement. If not, describe the handled material, feed size, impact condition, and expected service position so the supplier can ask the right follow-up questions.
How should a mixed quarry wear list be sent?
Use one line per item. Separate jaw plates, liners, screen panels, hopper parts, and GET items, then add quantity, drawing status, photos, and urgency for each line.
Why do two crusher wear part quotes vary so much?
Price can change because of material, weight, heat treatment, machining or drilling scope, inspection, packing, and whether the supplier has enough information to quote the same part.
