At present, most of coarse manufacturers adopt Raymond mills and ball mills, which can meet the current market demands to some extent. However, with the development of industrial modernization, environmental policies become more and more strict. Energy conservative, environment protection and high yield will be the future market demand. Based on this and adopted with German and China Taiwan superfine vertical grinding technology, Dongguan Vsunny Machinery Co., Ltd developed the VSCM series coarse vertical grinding mill. It use the high-class wear-resistant parts, and the fineness of ground powder product will be from 60~500 meshes. It is a high-tech machine with drying & grinding capability featured by high efficiency and energy-saving, and is widely applied in power plant desulphurization, construction putty powder, gypsum powder production and paper making industries.
