As the state 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 country has developed a successful one advanced level of similar products MLS3626 vertical roller mil (hereinafter referred to as MLS3626 vertical mill). This top research and development results, fill the gaps in our large vertical roller mill, to achieve our 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, the main content MLS3626 vertical mill technology development

Determine (a) the main parameters. According to the movement of materials with speed and strength in the disc of grinding, roller diameter, roller width, disc speed, material bed thickness, wind speed and other factors on the disk grinding speed; studied mill grinding capacity and bake dry capabilities, and according to the material test results on MLS3626 vertical mill, determining the type and yield MLS3626 vertical mill, power consumption indicators (mill main motor power), etc.; determine effective weight disc lining wear indicator according to guarantee this two life wearing parts are greater than 10000h.

(2) optimization of the design of the grinding mechanism. The main study of the impact 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 and the seat frame and other major bearing pressure were 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 take full account of the effects of heat stress.

Basic research and analysis, the development and design for MLS3626 efficient modular vertical mill classifier. Control key consideration regional component separator 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 separator design. Based on the analysis in the study of contemporary art and efficient modular separator (eg LVT separator, O-sepa separator, SEPOL separator, RAR separator, etc.), the development and design of efficient vertical mill  for MLS3626 combined classifier. Control key consideration regional component separator and particle motion, limiting the mill appear as irregular exercise, from the surface to reduce the cycle load, improve grinding efficiency.

(4) optimize the mill maintenance unit and other ancillary equipment design. The main disc, roller liner structure to achieve the 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 energy for the more high material moisture requirements; design next machine manual has, next to the machine automatically controls the remote control and operation functions of three electrical control systems. 2 MLS3626 vertical roller mill structure, working principle and main technical parameters

(1) structure. MLS3626 vertical mill mainly by the main motor, main gear, disc, roller set, frame body, tensioning device, separator, consisting of three gates, installation and maintenance, auxiliary transmission device and sealing air piping and other components, see Figure. (2) works. MLS3626 by air swept roller mill closed ......
