The cooled positive electrode material in the cooling ribbon machine is conveyed to the manual butterfly valve, falls into the feeding sleeve, and then into the conveying chamber. In the conveying chamber, it falls into the bellows. During the material's passage through the feeding sleeve, air is conveyed to the air inlet pipe and then to the air handling equipment at the top of the air inlet pipe. This ensures that the air pressure in the entire material conveying circuit remains normal throughout the entire operation, guaranteeing the smoothness of the transport.
