Introduction to Air Classification powderbulksolids

2021-4-21  Introduction to Air Classification. Oct 08, 2009. A.J. DeCenso. Air classifiers are preferred over fine screening in one or both of the following situations: 1) the rate is too high for fine screening; 2) the cut point is too fine for screening. Take for example an application in which calcium carbonate must be separated at 75 microns.

Understanding Vapor Barriers Building Science

2011-4-15  The confusion arises because air often holds a great deal of moisture in the vapor form. When this air moves from location to location due to an air pressure difference, the vapor moves with it. This is a type of migration of water vapor. In the strictest sense air barriers are also vapor barriers when they control the transport of moisture ...
