摘要： PURPOSE:To provide a molding sand treating method, which can correspond to the various kinds of sands having different composition recovered from a molding line and obtains unformized sand without distribution in the sand quality. CONSTITUTION:Since a first sand near a casting product in a master mold changes the composition by burning, after the removal of the foreign matter and a cooling process 83 of the sand are completed, by applying kneading 84 to be the first adding process of clay, moisture, etc., the quality is stabilized in some extent. Thereafter, the treated sand is joined into a second sand treating line X which is not affected from a casting product and for which the change of the composition is not generated and by applying the main kneading in the first kneading process 74 to the second sand, the stabilization of the quality of the first sand is surely attained together with the second sand. Further, a bypass line Z from a molding line is joined at the most upstream side of a treating line Y, and by introducing the shake-out of the sand in the next day generated on the operation of the treating line into the treating line Y, the stabilization of the quality to a third sand is surely attained.
