Specifically, the speed change device 10 is adapted to be connected to the rotary kiln to drive the rotary kiln in rotation, the speed change device 10 having a first input shaft 11 and a second input shaft 12. The first ac motor 21 is connected to the first input shaft 11, and the second ac motor 22 is connected to the second input shaft 12.
The first band-type brake device 31 is used for holding and releasing the first input shaft 11, and the second band-type brake device 32 is used for holding and releasing the second input shaft 12, so that the first band-type brake device 31 and the second band-type brake device 32 respectively brake the speed changing device 10.
The motor driving device 40 is connected to the first ac motor 21 and the second ac motor 22 for driving the first ac motor 21 and the second ac motor 22. The controller 50 is connected to the motor driving device 40 to control the first ac motor 21 and the second ac motor 22.

Thus, by employing the dual ac motor (i.e., the first ac motor 21 and the second ac motor 22) drive instead of the conventional ac motor and dc motor drive, the reliability of the system is greatly improved, and since the structure of the ac motor is simpler than that of the dc motor, the maintenance workload of the motor is reduced.
Meanwhile, the double band-type brake (namely the first band-type brake device 31 and the second band-type brake device 32) is adopted to brake instead of the traditional single band-type brake (namely a set of band-type brake device), so that the brake is not easy to slip, and when one of the first band-type brake device 31 and the second band-type brake device 32 fails, the other one can ensure the reliable brake of the rotary furnace, the reliability is higher, and the safety of the rotary furnace is improved.
