The invention discloses an energy-saving and explosion-proof mechanical activation device and a production process. The device comprises a cylinder body. A discharging device is mounted on the side wall of the cylinder body. A grinding door is arranged on the side wall of the cylinder body. The discharging device communicates with the grinding door. A big gear is mounted on the side wall of one end of the cylinder body. The big gear is driven by a small gear. A reducer is mounted on one side of the small gear. A coupling is connected to one end of the reducer. An electric motor is mounted at one end of the coupling. A main bearing seat is mounted at the other end of the cylinder body. The main bearing seat is fixedly connected with a main bearing seat frame. All smashing bodies are insulators, and no electron transfer exists in the friction process. Heat generated by the friction is discharged out of the equipment along with cooling water, the rotating speed of the equipment is extremely slow, nitrogen protection is adopted for an equipment cavity, and ground sulfur powder is conveyed out through a screw conveyor or a belt conveyor without wind exhaust equipment.
