Crusher and Screening Parts

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.
