How to grind cardboard efficiently?

Cardboard crushing is achieved through the use of our cardboard grinder, here is how the cardboard grinding wheel works:

Feeding

The initial step is to place the cardboard to be shredded into the feed opening of the cardboard shredder. This cardboard can be discarded cartons, paper or other paper products.

Cutting and shredding

Once the cardboard enters the machine, it is subjected to high-speed rotating cutting blades. These blades, usually in the form of hammers or razor blades, rotate and cut the cardboard into small pieces or sheets.

Screening

The cut cardboard is fed into a screen, usually a perforated metal mesh or sieve. The purpose of this screen is to control the size of the crushed particles. Smaller holes will produce finely shredded pieces of cardboard, while larger holes will produce larger chunky pieces.

Collection

Finished cardboard pieces fall through the screen into a container or bag for centralized collection. These fragments can be used for pulp recycling, packaging filling or other reuse methods.
