what happens to the crusher when the manganese liner begins to wear out

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.

Manganese - Is More Better? - Foothills Steel

2012-1-7  These properties make the manganese alloy extremely resilient, and the liners can take a lot strain before they become worn out. Any cracking or holes that appear in liners prematurely can usually be attributed to manufacturing errors. Manganese wear parts are sold in 3 common grades, 14% (Hadfield manganese), 18% and 21+% grades.

2020-3-19  The crusher liner wear profile gauge is used to inspect worn mantle and concave. These examples are the same for all other cone crushers. Inspection can be carried out on new liners to confirm the wear face profile, in the crusher during the life cycle to determine the change-out time, and to monitor the wear rate during service and maximise ...

Therefore as the machine setting is changed to maintain the proper CSS for consistent output gradation, less wear at the top of the liners results in a smaller feed opening.

When do you change cone liners? - elrus

2014-10-6  It is our experience that too many people lean towards too late, the optimum time to change a liner really depends on how much money you are prepared to lose to production losses to get the maximum use out of a wear component. The first condition that is optimum is that the liner change happens when you planned it.
