In general, documents, drawings, confidential documents, etc., stored or created in homes, companies, public offices, archives, etc. are discarded in the same way as general waste when the expiration date or no longer need to be stored. Receipts and confidential documents discarded in this way may be illegally abused in some cases. Such confidential documents to which personal and company information can be exposed are usually crushed by a document shredding device.

In addition to the paper documents as described above, waste synthetic resins or wood wastes, which are commonly generated around living, can be recycled for various other uses such as fuels if they are uniformly and evenly crushed and properly processed. Therefore, the development of an efficient device that can shred these shredded objects so that they can be recycled has been promoted from various angles.

In most cases, the shredding device has an inlet (hopper) for inserting the shredding object, and uses a device equipped with a cutting roller with a blade for cutting the shredding object introduced into the inlet. The crushed object is configured to be discharged downward.

The inventors of the present patent application devotes long research and development efforts in the field of shredding devices, and finely shreds not only document waste, but also synthetic resin or wood waste discharged as household waste or industrial waste, and recycles them as waste or fuel. We have developed a shredding device for this purpose. Such waste shredding device developed by the inventors of the present patent application is disclosed in detail in March 30, 2006 utility model registration application (application number 2006-0008444). (Hereinafter referred to as “predecessor”)
