PROBLEM TO BE SOLVED: To provide a liquid mixture supply device which prevents drying from an overflow line in a tank in which a liquid mixture (slurry) is stored, and prevents the cohesion of abrasive grains in the tank. SOLUTION: The liquid mixture supply device includes a supply tank storing the liquid mixture supplied to a machining device, a first liquid mixture supply path for supplying the liquid mixture stored in the supply tank to the machining device, a supply tank overflow path abolishing the liquid mixture when the liquid mixture stored in the supply tank increases over specified amount, and a water sealing means arranged in the tank overflow path. The water sealing means a water sealing box formed with an inflow hole into which the liquid mixture overflowing from the supply tank flows on an upper wall, a water sealing cylinder discharging the liquid mixture in the water sealing box, and a water sealing lid covering the upper end of the water sealing cylinder. A liquid supplying path introducing liquid which does not include abrasives into the liquid mixture collected in the water sealing box is connected to the water sealing box.
