Re: angle of repose
The angle of repose is simply the angle between horizontal and the material after the material is put on a horizontal surfuce from one point. For many raw material its about 40 deg. Angle of drawoff is the angle between horizontal and the material if you remove material from the buttom. Normally a few degrees higher. Wet sand can get fully up to 90 deg (and higher). Water has angle of repose and drawoff equal to 0 deg. The term is commonly used when dealing with bridge reclaimers.
FLS uses the following formula for the kiln retention time:
