Question: I have a question about cold-air intakes on gas furnaces. I recently had my old 80 per cent efficient gas furnace replaced with a high-efficiency unit that obviously has its own cold-air intake and exhaust pipes. Do I still require my old six-inch outside air intake on the return duct that was used for the old furnace?

B ecause the N.N.Zoubov Engineers SMCE Air Swept classifier is installed independently near the mill itself, it is adapted for any type of vertical coal mill without any need for changes in the mill itself, other than providing for the reintroduction of the clean tailings into the mill. In some cases the static separator installed in the mill can be maintained, …

Most modern classifiers fallunder the definition of centrifugal air classifiers, which utilize the opposing forces of centrifugal and drag to achieve a separation. The general theory depicting a single particle within an idealized flow field has been well documented in published literature. The centrifugal air classifier is as follows: 50 D ...

Due to the uneven materials dispersion and high dust concentration in industrial applications of turbo air classifiers, a high-efficiency rotor classifier was designed. Numerical simulations by ...

Air Classifiers. Air Classifiers use air flow and centrifugal force to mill and separate particles into fine and coarse streams. These air classifiers from Kemutec mill product as finely as 5 μm and eject it when the desired …

stability of the flow field on the classification surface is conducive to improving the clas-sification performance [13. 15]. The present research mainly focused on turbo air classifi-ers. Hence, the flow field distribution inside the classifier with a downward air inlet re-mains unclear. For a high-efficiency rotor classifier with a downward ...
