According to Xinxiang Great Wall Machinery related to human, GRMS series vertical roller mill in slag grinding, drying, powder and the integration of production, equipment has the advantages of simple process, low cost, low power consumption, very much in line with the green environmental protection, low cost concept of enterprise development, many visited Xinxiang great wall machinery the annual 6 00000 tons of slag vertical roller mill production line of customers more clear consciousness to the observabil

Polysius vertical roller mill (RM type vertical roller mill) 3-6 are polysius vertical roller mill structure schematic diagram, with surface grinding roller and a bow shaped disc, each grinding and by two narrow roller and installed together, the grinding roll with rotating disc movement, grinding and two rollers can respectively adjust speed with respect to the lap. Roller pressure is adjusted by hydraulic pressure to provide the required grinding pressure.

Energy saving effect of different grinding process, the pre grinding equipment in the whole system to undertake the grinding task, the corresponding energy saving effect is not the same. From the pre grinding, mixed grinding to some end grinding of the three ways of energy saving effect is more obvious than one. With the increase of the power consumption of the pre grinding equipment, the energy consumption of the mill is reduced, and the total energy consumption of the whole mill and pre grinding equipment is reduced.

Cement grinding system mainly includes the four parts: raw meal grinding and coal grinding, grinding clinker and slag grinding grinding, has been, cement plants, the production of grinding by ball mill, high energy consumption and high pollution become endemic in many cement plants. With the development of industrial production technology, the new type of environmental protection, energy saving and high efficiency of the vertical roller mill is gradually introduced to promote the domestic cement plant.

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 vertical roller mill (hereinafter referred to as vertical roller mill).

Vertical roller mill for short vertical mill, a cement raw materials, cement clinker, slag and slag grinding process used, has a simple structure, low cost of manufacture and use characteristics. Including between the body, the disc device and the transmission device, the body and the disc-centering means is provided to determine the structure of the rotational center of the bottom disc is fixedly provided with rotary guide means, through the rotary disc means rotatably supported on the rail body, the disc device and gear drive connection.

1, the vertical roller mill grinding roller body wear

Roller sleeve and grinding roller bearings are worn parts. Roller sleeve wear to a certain extent, can be used upside down; when the roller sleeve wear again, so that the mill output decreased greatly, when the mill is not sufficient to maintain normal production and should be shut down, replaced with a new roll sets.
The following steps should replace the ultrafine vertical roller mill sleeve or bearing

Tensioning gadget component: pre-load the actual roller is actually used with a hydraulic tensioning gadget. Hydraulic canister fishing rod pressure functioning on the actual stress via 3 structures, after which distribute with the roller comes home, roller pressure that's functioning on the actual materials between your roller and also the dish, respectively, about the tensioning gadget has the hydraulic accumulator canister to possess a dampening impact.
