Study On Separator Of Large-scale Vertical Mill

Large-scale vertical roller mill (Large Vertical Mill for short) is used as a devices to separate the grinding powder of the large vertical mill,and it is an equipment which integrate grinding, drying and separating into one and the main use is to grind and dispart cement, clinker and blast furnace slag, etc. Separators are the supporting equipment of the large vertical mill, so far, the design of separator has no sound theory in domestic and the existing separator performance is not high,so,to develop high-performance separator large vertical mill as soon as possible will speed up the process of Chinese and increase the market competitiveness of enterprise.This subject is the sub-topic issues of vertical mill product development topic of the Second Heavy Machinery Factory, and it is based on the developed scientific research projects and made the large-scale vertical mill separator for the study. According to the basic grade separator theory of particle hydrodynamics, the subject analysed the structure and the technical parameters, and bring forward the theoretical formula of the Separator Selection, the main content as follow:First of all, domestic and foreign development state of separator were also discussed, it summed up the characteristics of similar products to study the parameters which impact production and product fineness of the separator. Secondly, according to the basic theory of grading of particle hydrodynamics, it put forward the computing relationship formula of separator production, product fineness, separator power, and basing on this theory, it has designed the high-performance cage-shaped separation which is used in separating the cement raw material, clinker and blast furnace slag. At the same time, it Analyzed and summarized the various wear-resistant materials used for the separator, which provides a theoretical basis for the reasonable choices of wear-resistant materials and anti-wear method.
