Material crusher for double driving type pot furnace

The invention relates to a raw material device for production of an aluminum electrolysis pre-baked anode, and particularly relates to a material crusher for a double driving type pot furnace, wherein the material crusher is a device for adopting the pot furnace to calcine petroleum coke and crushing the calcined material. The material crusher comprises two sets of driving systems in symmetry arrangement along the center line; each set of driving system is composed of a first-level speed reduction mechanism, a second-level speed reduction mechanism, supporting seats and an eccentric wheel device and comprises the following particular structure: the input end of the first-level speed reduction mechanism is connected with an electromotor, the output end of the first-level speed reduction mechanism is connected with the second-level speed reduction mechanism, the output end of the second-level speed reduction mechanism is connected with a transmission shaft, the transmission shaft is arranged on the supporting seats, and the output end of the transmission shaft is connected with crushing tanks through the eccentric wheel device and provides power for the crushing tanks. Only the crushing tanks at one side are required to be stopped for maintenance when the crushing tanks at one side generate fault, so that the influence on the production is reduced, and the occupied area is reduced; and because each eccentric wheel device is arranged in the middle of the No.2 supporting seat and the No.1 supporting seat, so that the peak value transmitted to the base load is decreased.
