Better Material of Cone Crusher
Posted by Deddy from Medan, OT, ID on January 22, 2010
Hi Steve,
What is the better material supplied to have more longer life time for Cone Crusher? We currently use the 13% High Manganese Steel to crushing the Granite stone on site, but hope we can extend the life time by increasing the grade of material.
There are another grate like 18% of Mn and about 21% of Mn. What is the best material to pick? Does the higher grade can cause cracking possibility of Cone while being operated?
If you can determine each characteristic of those each grade it will be very appreciated.
Thank you.
Deddy
Usually, a given manganese wear parts supplier offers two grades of manganese; a regular grade which is around 12% and a premium grade which is around 18%-24%. To increase liner life with the premium grade one has to be crushing a higher compressive strength stone, granite would certainly fall into this category. I have seen that with customers using our premium grade manganese and crushing granite, their liner life has increase by 15%. This does not say that your liners will attain this added service life, but, you should experience some increased service life.
To answer your next question regarding cracking, one must first understand why the liners are lasting longer. Due to the nature of the premium grade manganese, the crushing surface will work harden to a greater extent. Anytime this occurs, you run the risk of cracks forming due to fatigue. We have found that the amount of trace elements help to limit this from happening, thus allows a set of liners to run full term without cracks forming.
