Vertical roller mill development and research

With the country vigorously promote technological innovation and new dry cement design optimization, in order to meet market demand for cement, relying Anhui Conch Group Zongyang two 2500t / d clinker production line of domestic construction projects, in 2001 the successful development of the country has a advanced level of similar products MLS3626 vertical roller mill (hereinafter referred to as MLS3626 vertical roller mill). This is a top research and development results, fill the gaps in our large vertical roller mill, to achieve the country 2500t / d cement production line technology and equipment of a major breakthrough. This paper mill in respect of research and development work of a late presentation outline. (1) Determine the main parameters. According to the movement of materials with speed and strength in the grinding disc, the roller diameter, roller width, disc speed, material bed thickness, wind speed and other factors on disk grinding speed; studied mill grinding capacity and bake dry capability, and according to the material test results on MLS3626 vertical roller mill to determine the type and yield MLS3626 vertical roller mill, power consumption indicators (mill main motor power) and so on; determining an effective weight disc liner according wear indicators to ensure this two life of wearing parts are greater than 10000h. (2) optimization of the grinding mechanism design. Studied the effects of the disc, the curvature of the roller grinding capacity, unit power consumption, in order to determine the optimal grinding curvature. Large parts of the disc holder and pressure frameworks were the main bearing static analysis and calculation of structures under dynamic loads, optimize the framework of cross-sectional dimensions determine the pressure to find the disc holder stress equally conducive to optimum shape of the casting process, and fully consider the impact of thermal stress analysis of the research, the development of modular design and efficient classifier for MLS3626 vertical roller mill. Key consideration separator area portion control and particle motion, limiting the mill appear as irregular exercise, from the surface to reduce the cycle load, improve grinding efficiency. (3) the development of highly efficient combined classifier design. Based on the research and analysis of contemporary art and efficient modular separator (eg LVT separator, O-sepa separator, SEPOL separator, RAR separator, etc.), the development and design for efficient vertical roller mill MLS3626 combined classifier. Key consideration separator area portion control and particle motion, limiting the mill appear as irregular exercise, from the surface to reduce the cycle load, improve grinding efficiency. (4) optimizing mill maintenance equipment and other ancillary equipment design. The main disc, roller liner structure to achieve maintenance and replacement easy, shorten the maintenance cycle, improve equipment operation rate; designed with air lock features three gates, in order to ensure better continuity of feed and can be adapted relatively high material moisture requirements; design manual bypass machine has, beside the machine automatically controls the remote control and operation functions of the three electrical control systems.
