[0080] This device, equipped with a conveying mechanism, enables the simultaneous transport and baking of pulverized lithium battery anode materials, significantly reducing the production cycle of lithium battery anode materials and increasing their production output.

[0097] When the lithium battery negative electrode material on the conveyor belt 8 is being transported, the heating motor 20 is started. The heating tube 18, which is fixedly connected to the heating motor 20, evenly conducts heat onto the conveyor belt 8. As the conveyor belt 8 passes by, continuous heating is performed.

[0098] When the conveyor belt 8 passes the cleaning plate 27, the dust attached to the conveyor belt 8 is rubbed off by the cleaning brush 28 which is in contact with the conveyor belt 8.
