Sand is extracted from the location at which it occurs by either a floating dredge or front loader. The dredge delivers a slurry of sand and water to the processing plant via pipeline, while the front loader simply scoops the sand up and into trucks or onto conveyor belts for transporation to the plant.
sand casting processes are a limitation to this technique. • Many new casting processes have been developed which can take into consideration the aspects of dimensional accuracy and surface finish. Some of these processes are die casting process, investment casting process, vacuumsealed moulding process, and shell moulding process.

Other methods for eliminating defects, although not nearly as practical, were core postbaking at 450F (232C) and use of core coatings modified with red iron oxide. BACKGROUND Surface and subsurface gas defects have always been common and troublesome defects in gray iron and other castings poured in green sand molds.

The Green Sand Molding Process The term Green Sand denotes the presence of moisture in molding sand and indicates that the mold is not baked or dried. Raw sand is mined and then processed to give it a consistent distribution of grain sizing. When processed for molding, organic clays are added to bond the grains together. A coal dust (known as Sea Coal) is added to control casting quality ...
