In order to move things and keep them safe, cardboard is created in large quantities for use in packing, shipping, and product displays. A second issue brought about by the widespread usage of cardboard is how to get rid of discarded cardboard without throwing it in the trash.
Cardboard shredders are a key component of the repurposing and remanufacturing of cardboard because they quickly and effectively break down cardboard fibers into a variety of forms. Although many businesses sell cardboard shredders, they are categorized into two types of operations: perforation and shredding.

In addition to the different ways that cardboard may be cut and shredded, there is another class of devices that are made specifically to pierce cardboard and use it in new ways. The blades of a cardboard perforator’s cutting cylinder are made to perforate and cut cardboard without actually cutting it. An extended, flexible, stretched, and cushioned type of paper that may be utilized as packaging material is the end product of the perforating process.
A perforator is said to be an additional technique for taking discarded cardboard and improving it for future use, even if it does not completely destroy the material and only cuts it into tiny bits.
Even though paper shredding generates some dust, not enough for it to be a major worry unless it’s done as part of an industrial process. Owing to the material’s size, a lot of dust is produced when shredding cardboard, which has to be collected and managed.
Dust-controlling cardboard shredders have a flanged exit above the cutting blades that is connected to a dust collector via ducting. A fan inside the dust collection chamber pushes the cardboard dust through a high efficiency particulate air (HEPA) filter, which collects the dust from the air and pushes the filtered air back into the surrounding area to guarantee smooth circulation of the dust-filled air.
Short air pulses are directed against the filter in the opposite direction as the flow of dust-filled air by compressed air in the dust chamber, maintaining the filter’s cleanliness and clarity.
Cross-Cut Shredders for Cardboard
A cross-cut cardboard shredder adds a second cut that goes across the long ribbons to perform the same functions as a strip-cut cardboard shredder. The cutting process produces minuscule fragments that resemble microscopic particles or confetti. The kind and size of the cut material, which can range from a fraction of an inch or a few centimeters to a few inches or decimeters, determines the differences between cross-cut shredders.
Industrial cross-cut shredders can be fed by conveyors and have a large capacity. Paddle wheel crushers with some designs compress the cardboard before it reaches the cutting blades, improving the cutting process. The premium alloys used to make cutters are able to resist repeated usage.
Shaft Dual Shredders
Cardboard shredders with two shafts operate silently and slowly. They are equipped with two sets of blades, each set positioned on opposing shafts. The two sets of blades that revolve into each other when engaged can shred thick, heavy, two- or three-ply cardboard. Compared to ordinary shredders, dual shaft shredders are more potent and dynamic and are capable of cutting through a variety of materials, including cardboard of any size or thickness.
Single motor cardboard shredders with twin shafts are the most common type. Certain versions use two motors, which boost the shredding process’s effectiveness and speed. The feed material is grabbed by the two cutting blades, which then shred it into tiny, minute fragments.
