01-11-2001· A rotary reclamation process that relies on dry attrition for sand processing installed at Western Steel Casting Co., Seattle, saved the foundry more than $70,000 in just under 6 months. The RSR 2000 Rotary Sand Reclaimer is produced by Roberts Sinto Corp., Lansing, Michigan, and Sand Molding Systems, Newaygo, Michigan.
As a consequence the dry attrition process usually allows re-use of only up to about 80% of the resin bonded sand, so this means that the remainder has to be disposed of. As the used sand contains a high level of phenolic and alkaline residues disposal is more of a problem and more costly compared with the disposal of some other used foundry sands.
There are three main options for sand reclamation: Primary attrition, secondary attrition and thermal. Primary attrition Primary attrition can be further broken down into three main types: primary attrition low-level, primary attrition high-level and combined shake-out/attrition. High-level refers to the loading height of the attrition unit.
• To achieve the maximum level of sand reuse, installed a 3 part system based on conventional primary dry attrition, secondary attrition and thermal reclamation processes. • Primary dry attrition uses high intensity vibration to reduce the sand lumps down to grain size.
