The utility model provides a feeding device of a Venturi dryer for an aluminum hydroxide gaseous suspension roaster, which is used for solving the technical problem that normal production is affected due to the fact that materials in the Venturi dryer are easy to fall when single-point feeding is adopted, and comprises an aluminum hydroxide stock bin, a feeding device and the Venturi dryer which are connected in sequence, the feeding device comprises a spiral metering scale, and the spiral metering scale is connected with the Venturi dryer through a material distributing pipe for distributing materials. The feeding mode that an electronic belt scale and a spiral feeder are combined is replaced by the spiral metering scale, the number of devices is reduced, the space of the devices is reduced, and the cost of the devices is reduced; multi-point feeding of the venturi dryer is achieved through the material distributing pipes, conveyed materials can enter the venturi dryer in a dispersed mode, the material falli
