The invention provides a carbon black and powder weighing control system and method, and the method comprises a fast weighing stage, a first slow weighing stage and a second slow weighing stage, and a new door closing value is dynamically assigned to control a weighing and discharging mechanism to stop discharging. Compared with a conventional weighing control method, one-stage slow weighing is added, the speed of the weighing discharging mechanism in the final discharging stage is further reduced, and the discharging error can be reduced. A dynamic new door closing value is used for controlling the door closing action of the weighing and discharging mechanism, and the determination of the dynamic new door closing value considers that the weighing and discharging mechanism stops weighing and the materials in the scale reach the stable weight of the weighed materials; the system has the function of automatically and dynamically adjusting the weighing parameters forwards and backwards, so ...
