In order to reuse the discarded ground film, a crusher is often used to tear the discarded ground film into pieces. The process of tearing the ground film will be accompanied by dust, which will pollute the surrounding environment. The dust will be inhaled by the staff, which will affect their health and reduce their personal safety.
[0003] The existing dust removal device for mulch film production collects and processes the dust generated in the process of shredding mulch films by setting dust covers on the upper side of the shredding box feed port and the shredding discharge position.
