Waste paper baling machine and paper shredder in paper recycling
When recycling all these kinds of papers and magazines, baling them into dense bales is a very essential procedure to save transportation and storage cost. Either vertical waste paper baling machine or horizontal waste paper baling machine can be used for baling paper, while shredding newspaper and magazines is highly suggested before baling as these materials in most cases are in piles, with very high original density. Shredding before baling will help these material be pushed through the chamber and the bales will be easier to be tied and handled. As for Auto-tie Horizontal Baler baling newspaper and magazines, it is suggested to equip with a “Fluffer” inside the hopper to shred the material into loose shape. Using a separate shredder to shred the material first and then convey the material into baler for baling is also a good option.
