Coal ash is a kind of industrial waste residue. Some studies show that more fine the coal ash is, higher activity the coal ash release,and more useful the coal ash finess is. It has been proven very effective as a cement performance enhancer which improved strength, permeablility and corrosion resistance properties. What’s more, it also can be widely used in baking free brick, cement plant, ceramics, glass, steel,plastic,ruber and highway foundation project. So the coal ash fine grinding industry spring up, to expand and develop widely coal ash application area.
We have cone crushers. We have usually wear problems. Life of concave wear plate is 60 days.We did experiment.We genarally use 120Mn13. Perhaps we are making heat treatment or machining. But Where?
You need to be more specific with a problem description. There are many reasons for wear. It is helpful to concentrate on your problem. First, give some details on:
