As someone who has been in the bulk material industry for 30 years, with LOTS of experience in bridging and ratholing within silo's, hoppers..etc, I can't seem to find any design drawings, internal operation or anything an engineer would appreciate to read on the AP feeders. I did find one small caption indicating the side wall slope on the AP is 45 degree's, which is considerably different then our standard 60 degree hopper walls. This would indicate they don't feel bridging is an issue, OK.
CEMA standards for an opening from a cone needs to be at least three times wider then the largest particule of material. Meaning that three particules, horizontally in line, need to be able to easily fit through the outlet opening. IS this the case with this feeder??, I can't tell, no drawings, nothing, nada. I am familiar with the Feed, as I use it, but in a Small moultrie feeder, and beleive that the surface tension on the pellets is very course, allowing for easy bridging and jamming.
