Crusher Chamber Wear Parts
Jaw plates, cheek plates, mantles and bowl liners, blow bars, impact aprons and hammer tips for jaw, cone and impact crushers.
Features
- Manganese steel work-hardens in service, so it suits compression crushing in jaw and cone chambers where load is sustained.
- Martensitic and ceramic-insert blow bars suit impact crushers, where tip hardness matters more than work hardening.
- Chamber profile is chosen with feed gradation and required product, since a coarse profile in fine feed wears without crushing.
- Jaw plates are turned end for end at the right point in their life, which recovers even wear across the plate.
- Wear parts are changed as a set in one chamber, because a new liner against a worn mating face crushes unevenly and cracks.
