The sucked material is conveyed through the pipeline to the breaker 4 to break up the lumpy material, which facilitates the material conveying in the pipeline. Then, the material is cooled to a suitable temperature by the cooler 5 to prevent scalding of the ton bag. Then, the material is conveyed under negative pressure to the rear buffer bin 7, and finally, the ton bag packaging machine 8 realizes the ton bag packaging.
