Thermal Sand Reclaimer Helps Foundry Eliminate 3000-Ton Sand Pile. (Case History).Badger badger, name for several related members of the weasel family. Most badgers are large, nocturnal, burrowing animals, with broad, heavy bodies, long snouts, large, sharp claws, and long, grizzled fur. Ironworks, Menomonie, Wisconsin
duc·tile adj. Easily molded or shaped. ductile susceptible of being drawn out without breaking. and austempered ductile iron Ductile iron, also called ductile cast iron or nodular cast iron, is a type of cast iron invented in 1943 by Keith Millis[1]. While most varieties of cast iron are brittle, ductile iron is much more ductile, as the name implies. 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. The foundry bought a Thermfire TF-2000 thermal sand reclaimer from Gudgeon Thermfire International, London, Ontario, Canada. The reclaimer is a 1 ton/hr gas-fired unit that includes a built-in cooling bed for a compact design. The foundry uses its mechanical reclaimer to break the sand lumps down and screen it to the thermal reclaimer. Since the new system was put in place in 1999, the foundry has used it for reclaiming both nobake sand and its 3000-ton sand pile. In addition to eliminating the waste sand, the thermal reclaimer produces high quality sand that can be used anywhere in the foundry. "The quality of the sand after it has been through the thermal reclaimer is so good that we can drop the chemical at the mixer mixer, either of two electronic devices in which two or more signals are combined. In the type of mixer used in radio receivers, radar receivers, and similar systems, a signal is translated upward or downward in frequency. from 1.2% to 1% and reuse reuse - Using code developed for one application program in another application. Traditionally achieved using program libraries. Object-oriented programming offers reusability of code via its techniques of inheritance and genericity. the sand in any of the processes in the foundry," says Badger Ironworks president Mark Forster. Today, the sand pile is nearly gone, and the foundry is paying for the system through chemical and sand savings. |
