Description

technical field

[0001] The invention relates to the field of office applications, in particular to a paper shredder and a paper shredding method thereof. Background technique

[0002] Under the situation of responding to the green theme of eco-environmental protection worldwide, secondary fiber has become an important fiber source for the pulp and paper industry. Therefore, the recycling and reuse of waste paper has attracted more and more attention. At present, the process of waste paper recycling is generally: sorting→shredding→deinking→removing residue, screening→washing→concentrating→bleaching→sending to beating. Almost every process of treatment consumes water and discharges waste water, but the largest amount of waste water is discharged in the deinking process, and various pollutants are also produced during the production of deinking agents to endanger the ecological environment. In addition, in the paper shredding process, a large part of the ink-free part that can...
