Intro to Size Reduction

grinding light materials to a fine particle size. 2. Without air, dusty material will take the path of least resistance, typically out the feed chute. In a pneumatic system, dust is controlled and contained because all material is pulled in a common direction. 3. The fan also aids in material transport to storage or next stage processing.

Sizing Ductwork for Dust Collection Systems

Steel grinding dust conveyed @ 3500 feet per minute (velocity). A typical grinder uses 500 cubic feet of air per minute (cfm) to control dust. To move this much air, select an appropriate size of ductwork – in this example, a 5-inch diameter duct yields just over 3500 feet per minute for 500 cfm air volume.
