High Abrasive Material
Posted by Dhruv from Nangal, OT, IN on April 29, 2009
Dear Sir, I am crushing river bed material which has silica around 70%. Please advise me which mateial jaw plate I should use that will give me longer life.
There is more than one thing that determines the alloy recommended in jaw crushers. Given all other things equal, if the silica content is 70% and the compressive strength of the stone is above 40,000 psi than we would recommend a premium grade of manganese. If the compressive strength is below this number, chances are that the manganese will not work harden to its full extent. This basically means that you could by the premium grade of manganese and not achieve its full benefits.
