Cone Crusher

 · Check the drain of the water seal. If there is no water in the water seal, the crusher must stop running. Pay attention to the sound of engine and gear, and check whether the working current of the motor is normal. Check the wear of liner regularly, and pay particular attention to the fixed bolt on the adjusting ring which may make liner loosen.

Work hardening in cone crusher liners

Cone crushers are used in the aggregates and mining industries to crush rock material. A computer program was previously developed in order to predict the geometry of a worn cone crusher. In that model there was some discrepancy between predicted and measured geometry. The liners in rock crushers are made of manganese steel, a material known for its capability of work hardening.

Manganese steel wear liners — SRP

Austenitic manganese steel – steel alloyed with more than 10% manganese – is work-hardening. That means that high impacts – like those in a crushing chamber for example – cause the formation of a extremely hard surface layer that is two to three times harder than the rest of the alloy If impacted enough, this results in a hard exterior layer backed by a softer core.
