Modeling and Control of Roller Compaction for

Mar 18, 2010The simulation case studies show the model can predict the ribbon density and gap width while varying roll pressure, feed speed, and roll speed. The roll pressure influences the ribbon density much more than roll speed and feed speed, and the roll gap is affected by all three input parameters.

CONVEYOR PULLEY SELECTION GUIDE pcimfg

STEP #1 Determine the Face Length of the Conveyor Pulley. The face length of a conveyor pulley is a derivative of the conveyor belt width. In bulk handling applications, an adequate pulley face length is one that is 2" or 3" greater overall or 1" to 1.5" greater on each end than the overall width of the conveyor belt.

Angle of dip The angle at which strata or mineral deposits are inclined to the horizontal plane. Angle of draw In coal mine subsidence, this angle is assumed to bisect the angle between the vertical and the angle of repose of the material and is 20 for flat seams. For dipping seams, the angle of break increases, being 35.8 from the vertical for a 40 dip.
