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.

Coal ash fine grinding is different from cement grinding. It itself is a kind of powder, the feeding size is min, so it is hard to process to super fine by traditional grinding technology. Henan Liming Road & Bridge Heavy Industry Co.,Ltd produces High pressure suspension mill, LM vertical Mill, and Three rings Mill all can be used for resolving this problem. These three types of mills can process coal ash to 45μm or less. The production capacity can vary from several tons to tens of tons. We always stay abreast with the changing market needs and are always ready to improve the machine performance to meet various of costomers demands.
