Rotary Dump vs Rotary Car Dumper

I linked rotary dump to rotary car dumper and it was twice reverted by Moreau1, who asserted that "The latter article only describes a machine used to unload a full-size railroad car." This is simply not true. The rotary car dumper article clearly discusses both topics. The technology of rotary dumping does not depend much on the gauge or the size of the car, and the article contains numerous references to dumping mine cars as well as full-size railroad cars. There was a rotary dumper on the D&RGW for dumping 3-foot gauge rail cars into standard gauge cars. Surely dumpers for 3-foot 6-inch gauge mine cars are not that different, except for issues of loading gauge, since mine cars for thin-seam coal mines tended to be quite low. Look at the 20-ton 3-foot 6-inch gauge mine cars formerly used at the Henderson molybdenum mine, their profile isn't that different from common-carrier hoppers (except they were bottom-dump cars, so no rotary dumper at that tipple), Manufactures such as the Ottumwa Box-Car Loader Company built rotary dumpers for both railroad and mine usage -- they didn't care about the difference.

Here is an ad clipped from Rotary car dumper reference list that makes clear that there is no real distinction between mine car and railway dumpers: Car Dumper Equipment Company, The Mining Catalog (Metal and Quarry Ed.), Keystone, Pittsburgh, 1921; page 295.
