Abstract: Provided is a mixing and adjusting method for foundry sand that uses a sand muller, having weight measuring means for measuring a weight of the foundry sand to be mixed, water content measuring means for measuring a water content of the foundry sand to be mixed, water pouring means for pouring water into the foundry sand, and CB value measuring means for measuring a CB value of the foundry sand during mixing. The method includes calculating a total supplied water amount till the measured CB value of the mixed sand becomes larger than the lower limit value of a target CB value range, determining the total supplied water amount as a necessary supplied water amount corresponding to the water content in the foundry sand that is to be mixed, and determining, from an additionally supplied water amount during the additional water pouring and the CB value of the mixed sand subjected to the additionally supplied water mixing, a ratio of a variation in the CB value corresponding to the additionally supplied water amount.
