Abstract (en)
[origin: US2006151145A1] The invention relates to a method for producing a core sand and/or molding sand for casting purposes. According to said method, a basic granular mineral molding material such as silica sand is mixed with an additive based on an organic or inorganic component, a binding agent being optionally added. According to the invention, the additive is coarsely ground prior to the mixing process, more than 50 percent by weight of the grains having a minimum size of approximately 0.05 mm.
