Air Velocity - an overview | ScienceDirect Topics

Because air velocity is dependent on buoyancy forces when air heats, the fins on a natural convection heat sink must be oriented vertical. The low air velocity requires much larger fin spacing than with forced convection. Steinberg recommends that the fin spacing should be a minimum of 0.60 inches (1.52 cm) in perfectly still air [18, p.113].

The Lime Industry's Problem of Airborne Dust

Hammer mills may be used if the stone is not abrasive. For pulverizing, a hammer mill, rod, ball, or tube mill, or an edge-running roller mill may be used. For extreme fineness, closed circuit grinding in air-swept mills with air classification is required. Occasion-ally, stone may be dried in a rotary dryer to assure better grinding.
