Total clay of 2.20% was obtained …

to determine clay content of new sands, waste sand without washing (A), and waste sand with detergent washed varying 0.2, 0.3, and 0.4% (B-D), respectively. The reaction of compounds in making moulding sand increase the amount of clay content, it appeared that waste sand without washing has the highest clay content.

 — The AFS 2210-00-S methylene blue clay test (MBT) has been used as a part of foundry control programs to determine the active clay percent in green sand since 1967.1 Active clay content is an approach to quantify the number of smectite clay minerals in a bentonite or molding sand. These minerals control bentonite properties and act as …

 — A realistic economic look at 20% clay and carbon reduction in consumption will save the average foundry at least $350 per ton, based on the amounts of clay and carbon consumed. The proven technologies …

Understanding the basic properties of green sand and the equipment required to operate a green sand foundry are important for anyone in related casting industries. Green sand molding, also referred to as clay-bonded sand molding, is the most widely used type of "bonded sand" in modern foundries worldwide. Molten metal is poured into green ...

 — Accuracy and repeatability of material addition is critical. The free flow of sand itself is critical to ensure a consistent sand flow for the no-bake process. Water is the kiss of death – as little as 0.2% moisture on the sand will alter the sand flow rates significantly. Chemical performance also will be inhibited.

 — The American Foundry Society has long been committed to creating and maintaining procedures for mold and core testing.

 — Foundry sand is the raw material required for making metal-casting sand molds, which are frequently recycled during the casting process. Foundry sand loses its quality after repetitive use, making it unsuitable for use in the process of manufacturing products, and later, is subsequently thrown away as waste, i.e., WFS (Ankush et al., …

 — The AFS clay-grade washing and sieving of the washed sand needs regular review, and these tests, along with optimum additive rates, are the keys to success in a green sand system.
