Working principle: when the massive titanium dioxide powder subjected to washing and filter pressing is subjected to drying treatment, firstly, a feeding conveying mechanism is started, after the feeding conveying mechanism is started, a rotating shaft of a driving motor II drives a driving rod and a winch wheel on the driving rod to synchronously rotate, the winch wheel initially breaks the massive titanium dioxide powder in a storage bin while rotating, and the titanium dioxide powder in the storage bin is conveyed into a breaking and grading mechanism for subsequent treatment through a conveying pipe along with the rotation of the winch wheel; after titanium dioxide powder enters the crushing and grading mechanism, the crushing and grading mechanism and the hot air drying mechanism are synchronously started, a fan of the hot air drying mechanism firstly injects wind power into a treatment cavity of the treatment box, air entering the treatment cavity is heated and warmed through a heating wire on a mounting column firstly, then air flow after the heating and warming forms a hot air tangent through a tangent guide plate, and then the hot air tangent enters a wind collecting cover of the crushing and grading mechanism; at this time, the crushing and grading mechanism is started, hot air tangential line entering the air collecting cover enters the bottom of the drying cylinder through the air vent, a strong rotary air field is formed under the drive of the stirring and crushing plate, meanwhile, strong shearing, blowing and rotating effects are generated on the titanium dioxide powder by hot air, so that the titanium dioxide powder is subjected to centrifugation, shearing, collision and friction to be micronized, mass transfer and heat transfer are enhanced, larger wet titanium dioxide particles are mechanically crushed under the action of the stirring and crushing plate at the bottom of the drying cylinder, particles with lower moisture content and smaller granularity are lifted by the rotary air flow, the particles are further dried in the lifting process, the solid phase is larger than the gas phase due to the rotary flow of the gas phase and the solid phase, the relative speed between the solid phase and the gas phase is higher, the mass transfer and heat transfer of the two phases are enhanced, the titanium dioxide powder is screened by the grading and screening plate on the drying cylinder under the rotary action, the larger wet undried particles fall back to the bottom of the drying cylinder to be continuously crushed and dried, and all the titanium dioxide powder after the drying treatment enters the respiratory collecting mechanism;
