Kneading sand property adjusting system and property adjusting method

摘要

A kneading sand property adjusting system and a property adjusting method capable of accurately performing kneading control. A kneaded sand property adjusting system includes a kneading device, a kneaded sand storage hopper for storing the kneaded kneaded sand, and a molding apparatus for molding the kneaded sand conveyed from the hopper as molding sand. 24, a control device 25 that performs water injection control until the kneaded sand being kneaded satisfies the target properties, and kneading sand amount measuring devices 11 to 14 that measure the amount of kneaded sand stored in the kneaded sand storage hopper 10. The control device 25 stores the number of kneading batches in association with the kneading sand properties at the time of kneading in the kneading batch, and based on the amount of kneading sand measured by the kneading sand amount measuring devices 11-14. The number of kneading batches corresponding to the molding sand put in the molding apparatus 24 is calculated, the properties of the molding sand are associated with the stored kneading sand properties based on the calculated number of batches, and these property values are used as the basis.
