This unit separates the clay particles from the sand grains in a sand by means of rapid agitation. The clay grade is held in suspension, removed by means of a syphon, and is determined by loss in weight. II DESCRIPTION The sand washer assembly consists of a motor stirrer unit, glass wash beaker, cleaning brush, metal stand, syphon tube and ...
years in binder and sand technology giving the foundries greater opportunity to choose and control these basic foundry raw materials. Since casting surface finish depends largely on sand particle grading, it might be supposed that a proper selection of a particular grade of sand would be the only requirement to achieve the desired

Foundry sand is at the very center of sand casting. It can handle the heat of the molten metal, create a huge variety of shapes and details, and be reused again and again. Learn how foundry sand is made, used, and recycled.
Burnon (also known as burnedonsand or burntonsand) and metal penetration are common surface defects encountered in sand casting of steel. The Glossary of Foundry Terms [1] defines burnedon sand as "A misnomer usually indicating metal penetration into sand resulting in a mixture of sand and metal adhering to the surface of a casting.
Foundry sand once used must be thoroughly water scrubbed and water washed to remove objectional bonding materials, clay slimes, and fines. Such treatment will greatly extend the life of the sand and will cut to a minimum the requirements for new sand. Foundry castings made from molds using this reclaimed sand, can also be maintained up to the ...
