PURPOSE: A shotball system for shot blast is provided to reduce the processing time by injecting a fixed amount of shot balls all the time, thereby improving productivity. CONSTITUTION: A shotball system for shot blast comprises an accelerating unit, a blasting unit, a shotball supply unit, and a shotball inlet unit. The accelerating unit increases the rpm of a rotary shaft(3). The blasting unit is fixed to the rotary shaft, and includes a blast pipe(5) and an impeller(10) for blasting shot balls. The shotball supply unit includes a shotball supply pipe(20) and continuously supplies a fixed amount of shot balls to the blast pipe and the impeller. The shotball inlet unit is equipped with an inlet valve for letting shot balls into the shotball supply pipe.
