The invention discloses a cooling temperature conditioning method of rutile titanium dioxide. The cooling temperature conditioning method of rutile titanium dioxide is able to improve the conditioning precision and improve the sensitive heat recovery rate. The method comprises the steps of determining the temperature range of titanium dioxide during discharging from a cooler according to the cooling process requirement; detecting the rotating speed of the cooler, the cold air supply quantity and the temperature of titanium dioxide during discharging from the cooler when the cooler runs; determining whether the detected temperature of titanium dioxide during discharging the cooler is within the temperature range of the titanium dioxide during discharging the cooler as process requirement; then correspondingly regulating the rotating speed and cold air supply quantity of the cooler; repeatedly circularly adjusting at time intervals t. The invention also discloses an automatic control method of the cooling temperature conditioning method of rutile titanium dioxide. With the adoption of the cooling temperature conditioning method of rutile titanium dioxide and the automatic control method, the conditioning precision can be improved, the sensitive heat recovery rate can be improved, and meanwhile, the workload of workers is decreased, the production efficiency is improved, and the production cost is decreased.
