with the mill housing, the grinding forces are directly transmitted into the foundations. No grinding forces act on the mill housing; the outer grinding-roller seal between the roller and the housing minimises the intake of false air. Visual inspections may be per- formed at any time. Thanks to the encapsulated roller unit, tradi -

The ASME B16.5 code requires that the flange face (raised face and flat face) has a specific roughness to ensure that this surface be compatible with the gasket and provide a high quality seal. A serrated finish, either concentric or spiral, is required with 30 to 55 grooves per inch and a resultant roughness between 125 and 500 micro inches.
Raw mill fan in cement industry carries gas and raw meal. The pressure drop in raw mill fan is very high. If a vertical roller mill is used for raw grinding in cement industry then a large raw mill fan is installed. Usually cement industries use centrifugal fans to carry out this process. Induced Draft Fans. Induced draft fans supply the ...

Coal mill is also called coal pulverizer or coal grinder. It is a mechanical device used to grind raw coal into pulverized coal powders. The most used coal mills in cement plants are air-swept ball mill and vertical roller mill.. At present, most cement plants use coal as the main fuel in the clinker production process.
The rotating seal faces are fixed to the shaft, and they seal on a plane that is 90° opposed to the shaft's axis. This effectively eliminates abrasive wear to the shaft—and in so doing, eliminates the need to replace or resurface a prime overhaul component, saving labor, time and materials during periodic overhauls.
