Thermal Sand Reclaimer Helps Foundry Eliminate 3000-Ton Sand Pile

摘要

Badger Ironworks, Menomonie Wisconsin, is a 40-employee green sand and nobake foundry that pours 100 tons/wk of gray, ductile and austempered ductile iron and Meehanite metals.The foundry began mechanically reclaiming its sand in 1985, dumping the excess created by new sand additions and hauling it to a local landfill. As haul-out prices escalated, the foundry was forced to dump the used sand on its property and watch the pile grow. When the sand pile reached 3000 tons in 1999, the foundry searched for a new solution for its excess sand.
