How to Identify Crusher Wear Parts Before Quotation
Identify jaw plates, cheek plates, mantles, concaves and other crusher wear parts using model, serial number, part number, dimensions and application data.
A crusher size or phone photo alone is rarely enough for a safe parts quotation. Match the machine identity, part identity, dimensions, alloy and crushing application before approving a replacement.
1. Identify the machine before the wear part. Record the manufacturer, exact model, serial number and any configuration suffix. Crushers with similar names can use different chambers, mounting patterns or part revisions.
2. Photograph and measure the old part correctly. Clean enough of the part to expose casting numbers and mounting features. Take square-on photos, not only close-ups, and show a ruler or marked dimensions for critical points.
3. Match alloy and profile to the crushing application. Jaw profile and alloy selection depend on feed gradation, rock or ore characteristics, impact, abrasion and operating conditions. A harder alloy is not automatically better if the application has high shock loading.
4. Approve a matching sheet before production. The purchase approval should show the machine model, part description, drawing or verified dimensions, material grade, quantity and supplier deviation. For non-OEM replacements, explicitly confirm that fit and performance responsibility follows the written approval terms.
- Crusher brand, exact model and serial number
- OEM or casting number from the old part
- Photos of both sides, mounting points and worn profile
- Critical dimensions with a ruler or dimension sketch
- Part position: fixed jaw, swing jaw, mantle, concave or cheek plate
- Feed material, maximum feed size and target product size
- Known alloy or previous service-life information
- Quantity, urgency, destination and preferred shipping method
- Machine nameplate and serial-number photo
- Equipment manual or parts-book page when available
- Current chamber configuration and closed-side setting
- Any previous supplier drawing or confirmed part number
- Whether the machine has been modified or rebuilt
- Required fixed/swing jaw or upper/lower mantle and concave position
- Identification: Casting number, stamped number, logo, revision and any readable markings.
- Overall dimensions: Length, width, thickness and approximate weight when known.
- Mounting geometry: Hole spacing, wedge locations, hook shape, seat profile and bolt details.
- Wear profile: Photos showing tooth profile, corrugation, remaining thickness and unusual breakage.
- Part position: Mark fixed/swing, left/right, upper/lower and installation orientation.
- Rock/ore type and, when available, abrasion and work-index information
- Maximum feed size, gradation and moisture or clay content
- Target product size and expected throughput
- Current liner life in operating hours or tonnes
- Observed failure: normal wear, cracking, loose mounting or uneven wear
- Priority: service life, throughput, product shape or reduced downtime
- Dimensioned drawing or signed comparison sheet
- Material grade and hardness or chemistry report requirement
- Unit weight and quantity per machine set
- Fastening kit, wedges, bolts or backing material included/excluded
- Packing method for heavy castings and lifting-point arrangement
- Inspection photos, marking and dispatch evidence
- Can a jaw plate be quoted from crusher size only?: It is risky. Use the exact model, serial number, part or casting number, photos, dimensions and application information to reduce mismatch.
- Why does the feed material matter for a wear part?: Rock abrasiveness, impact, gradation and moisture affect the suitable tooth profile, alloy choice and expected wear pattern.
- What if the casting number is unreadable?: Send full-part photos, mounting details, critical dimensions, machine identity and a parts-book reference. A drawing or sample may be required before production.
- Can different crusher parts ship together?: Yes when weight, packing, readiness and destination allow consolidation. Heavy castings require a packing and handling plan.
