A titanium spiral conveyor solves the problem that an existing spiral conveyor is not suitable for conveying strong-corrosive materials. The titanium spiral conveyor is characterized in that a shaft head shaft is sleeved with a first casing pipe and a second casing pipe, the first casing pipe and the second casing pipe are welded into a whole, a plurality of core bar installing holes corresponding in position are machined in the shaft head shaft and the second casing pipe, and core bars are inserted in the core bar installing holes; gaskets are arranged on the core bars, a titanium surfacing layer is surfaced on the core bars, and the shaft head shaft, the core bars, the first casing pipe, the second casing pipe, the gaskets and the titanium surfacing layer are integrated; and a shell, a spiral shaft support, shaft pipes, a shaft pipe connecting piece, spiral blades, the first casing pipe, the second casing pipe, the gaskets and the titanium surfacing layer of the spiral conveyor are made of titanium materials, and the shaft head shaft and the core bars are made of steel. The titanium spiral conveyor has the beneficial effects that the strength of the spiral shaft is guaranteed, and the corrosion resistance of the spiral shaft is guaranteed as well; the spiral conveyor can meet the requirements for the work condition strength and the corrosion resistance; and the titanium spiral conveyor is simple in structure, safe and stable in running and long in service life.
