Factors to consider before designing a cement ball mill

Ball mill, cement mill as cement plant's main equipment, the power consumption is very large, (about 60 ~ 70% of the entire plant electricity consumption), therefore, whether the design of products or technical and economic indicators of production, for the successful operation of the ball mill equipment are of great significance. In the production of ball mill, must be considered from the following aspects of the requirements and economic indicators. 1. Reliable operation of cement ball mill. Ball mill in order to smooth and reliable operation, must first ensure that the installation is reliable. If the strength, stiffness is not enough, the machine can not be safe operation, become a pile of scrap iron. Therefore, we must first meet the strength conditions and stiffness conditions in order to ensure long-term safe operation of the machine; while the main machine easy to operate and high sensitivity; reasonable structure and high productivity, small size and nice appearance; low power consumption and low cost. 2. Ball mill manufacturing process perfect, reasonable structure. First of all, the structure of the ball mill must be simple and convenient. That is, the machine structure should be as simple as possible, the machining should be as little as possible, the machining process of the parts should be good, and the manufacturing man-hours should be less. the new materials are cheaper and easier to obtain, as far as possible to weld instead of casting, iron instead of steel, less non-ferrous metals and rare metals. At the same time, the overall design, we should focus on the use of standardized parts instead of special parts to reduce the special parts of the type and quantity; should also take into account the assembly requirements of the machine, the assembly process is easy to mechanization. 3. Pre-consider ball mill installation and transportation. Ball mill as a large equipment, must take into account the transport problems in the future, and the installation of ball mill equipment in place. The installation of the machine is simple and reliable; the structure is convenient for the loading and unloading of the modern transportation equipment; the technical conditions are strict and not demanding, that is, the economy is reasonable. In addition, preferably the components can be combined separately, easy to install separately, each group of components is lightweight and not heavy, in order to reduce the labor intensity of workers. In summary, several aspects of the ball mill requirements are often contradictory. Therefore, in the design and production, it is necessary to fully investigate the research, consider repeatedly, compare, in order to choose a more reasonable plan, extensive solicitation of opinions, setting out the preliminary design and the overall design of the main data, size, which is the basis for future theoretical design principles.
