Pendulum type powder mill central axis twin drive apparatus

The utility model discloses a double transmission device for a central shaft of a pendulum pulverizer used to grind powdered ores. The transmission device comprises at least two belt pulley transmission mechanisms which are evenly distributed around the central shaft of the pendulum pulverizer; in general, the transmission device adopts two belt pulley transmission mechanisms which are symmetrically arranged on both sides of the central shaft respectively; each belt pulley transmission mechanism is a commonly used two-level speed reduction transmission mechanism which comprises a first-level speed reduction driving belt pulley, a first-level speed reduction driven belt pulley, a second-level speed reduction driving belt pulley and a second-level speed reduction driven belt pulley; the second-level speed reduction driven belt pulley which is public is coaxially and fixedly connected with a shaft end on the bottom of the central shaft. Because the belt pulley transmission mechanisms are symmetrically arranged,
