Coal Moving Grain Auger | Coal Bins & Chimneys - Coalpail.com

As I remember, the manufacturer specd 400 rpm for grain. I'm using a 4" grain auger with the factory pulleys it came with to move rice coal. Works great. Loads up a 250# hopper in about 30 seconds. Try it, it may work just fine as is. I have a 5” at 345 rpm, a 4”at 383 and a 3” flex at 52 all with pea.Long circular auger holes or rectangular entries are punched into the coal seam from the highwall left by the previous surface mining operations to recover part of the remaining coal reserve.Highwall Mining: Design Methodology, Safety and SuitabilityBundy Auger Mining, Inc.
