Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Movable Jaw Plate
Compresses material against the fixed jaw plate in each cycle and is a principal high-consumption wear part in the crushing chamber.
Movable Jaw Plate (Movable / Swing Jaw Plate)— Jaw Crushers Wear part, position 02.
Location and Function
| Material Options | Austenitic high-manganese cast steel, such as Mn13Cr2, Mn18Cr2 or Mn22Cr2, selected for the OEM chamber profile and feed material |
| Typical Properties and Acceptance Criteria | Verify solution heat treatment, impact toughness, work-hardening conditions, internal casting quality and tooth crest integrity. The moving jaw plate is particularly affected by alternating loads and uneven wear. Seating contact, wedge preload and feed distribution matter as much as the material grade. |
| Principal Failure Mechanism | Sliding or three-body abrasion, localized impact and cracking around fastener holes |
Information Required for RFQ
- Equipment manufacturer, machine model, serial number, model details and latest drawing revision;
- Part dimensions, unit weight, key tolerances, assembly and fastening method;
- Current material, chemical composition, heat treatment, hardness and mechanical property reports;
- Processed material, maximum particle size, hardness/abrasiveness, moisture and tramp material records;
- Speed, load, temperature, pressure, process medium chemistry and continuous operating time;
- Failure photographs, wear measurements, crack/fracture locations and current service life;
Materials and values are for preliminary engineering selection. Final chemical composition, heat treatment, hardness and dimensional tolerances must follow the OEM drawings and technical agreement.
