In the mill industry, people are very clear, cement mill equipment is the main equipment for hard materials for grinding, and, along with the progress of society, the development of science and technology, our team also conducted a reform movement ball a few times, developed from the old to the small horizontal ball mill now has different properties. But now many of ball manufacturers for the sake of cheap, still in accordance with the basic theory of the old designs to build machine, set the new mill and disregard. We all know the old mill consumption high, low yield, accidents, maintenance of large, low operating efficiency, these problems are restricting the pace of mill equipment, and the international production of new mill in the comprehensive section electricity, growth, product fineness stability has its significant feature on. We use the new cement mill can handle now spread in the city sludge, waste, and also avoid burning understanding of carbon dioxide, carbon monoxide and other dangerous gas power plants. With respect to the use of municipal waste incineration plants, cement co-processing mill rubbish more thoroughly, it can achieve zero pollution, zero emissions.
