Abrasion wear of austenitic manganese steels via jaw
The abrasion wear of the austenitic manganese steels with 12% Mn and 20% Mn was evaluated via jaw crusher tests. The abrasive mass (i.e. gravel) used per test was 100 kg and 14.3 mm of mean sized particles. The wear characterization was carried out with the evaluation of mass loss, hardness profile, worn surface roughness, and wear micromechanisms.

Know-how
Easy maintenance & low wear. The main wear parts of the jaw crusher are its fixed jaw, moving jaw and cheek plates which can be changed easily and quickly. In contrast to impact crushers, jaw crusher wear parts have a comparatively long service life but jaw crushers cannot achieve the same reduction ratio on material.

Rubber Abrasion Resistance
Abrasion resistance is the ability of a material to resist mechanical action such as rubbing, scraping, or erosion that tends progressively to remove material from its surface. When a product has abrasion resistance, it will resist erosion caused by scraping, rubbing, and other types of mechanical wear.
