Mill fan VM is installed in boiler units to prepare for transportation of coal dust, which does not contain aggressive and explosive particles. Dust content should not exceed 80 g per 1 m3 of air. Mill fans are applied in ferrous and nonferrous metallurgy and other types of heavy industries, where it is necessary to transfer air in non-aggressive environmental conditions. At the same time, air temperature can vary from -30 C to +200 C. Mill fan VM can operate at external environment temperature from -40 C to +40 C at air humidity not more than 80%.

In driving wheel design, it is possible to manufacture different number of blades (from 10 to 16), the casing is made of corrosion-proof and corrosion-resistant metal. Scroll walls are enforced by finning for more durability. The angle of scroll rotation reaches 270 degrees; its edges can be cut if necessary. Rotation speed of the mill fan is up to 1500 min.-1 (maximum).

At ordering of VM mill fan it is important to determine precise aerodynamic characteristics, it will allow to prolong operating life of the equipment and to provide correct air circulation. We do not recommend to be engaged in parameter calculation by your own, because it is necessary to apply very difficult calculations. Address our experts for this purpose. We produce VM mill fans on our own platforms. They can be intended for aggressive media — due to titanium or stainless steel materials while designing. Our Design department experts can develop the whole fan construction through and adjust it to any conditions and requirements. Before start-up of the equipment, experts conduct its examination and balance at a site by means of a mobile complex. At request, the Customer can order fans, imported from Reitz Manufacturer.
