The present disclosure relates to a novel protective rotary kiln apparatus. The novel protective rotary kiln apparatus includes a rotary kiln body, a transmission device, a sealing device, and a shell, where the rotary kiln body and the sealing device are located inside the shell, and the transmission device is entirely or partially located inside the shell; the transmission device is configured to drive the rotary kiln body to rotate; and the shell is stationary and keeps in a sealed state during production. The shell can provide heat preservation, wind protection, rain protection, dust protection, improved sealing performance, energy conservation, and protection for the rotary kiln body. Moreover, even if leakage occurs in the rotary kiln body, gas or solid leaking out can enter the shell, the shell keeps in the sealed state during production, and thus the gas or solid leaking from the rotary kiln body can be confined in the shell without further leaking to the exterior of the shell, and the rotary kiln body is isolated from external environment. The rotary kiln body is not in contact with the shell, so that the production safety can be essentially ensured. The shell is stationary, basically requires no maintenance, and can be safely used for a long time.
