When presented with the opportunity to meet a customer’s requirements for storing stone and aggregates (crushed rock and mineral fragments) weighing 70#/ft.3 (1,121 kg/m3), SCAFCO engineering responded. The result is seen here while still under construction. This is a 30’ (9.14m) diameter SCAFCO hopper bin with ten rings which is 51’-8” (15.74m) eave height. Note that this special bin is heavily reinforced and has no roof. Note also, the shell around the hopper, the giant door for access around the hopper, and ladders and multiple platforms.
