Shredder Machine

What is a shredder used for?

Shredder machines pre-shred large and thick plastic in the first stage of the recycling process. Because they work on the low-speed, high-torque principle, they handle demanding inputs such as drums, barrels, pallets, pipe, big bags and baled material without jamming. The resulting coarse pieces are usually reduced to a finer flake size at the next stage in a granulator. Low-noise operation, easy blade replacement thanks to the housing system, and manufacturing from special materials that resist the abrasive nature of plastic are the standout qualities of İnan Tech shredder machines.

Shredder or granulator?

The two are not alternatives but complements: the shredder pre-shreds, the granulator refines. For bulky and thick material, using a shredder first and then a granulator both increases efficiency and protects blade life.

Where is it used?

• Drums, barrels, IBC tanks and thick packaging
• Pipe, profile and injection scrap
• Volume reduction after bale opening
• Industrial and municipal plastic waste

Single-shaft or double-shaft?

Single-shaft shredders push the material toward the rotor with the help of a pusher and generally work through a screen, delivering a more homogeneous, size-controlled output; they are efficient with uniform and moderately demanding materials. Double-shaft shredders, on the other hand, generate high torque with their two counter-rotating rotors and pre-shred mixed, bulky and resistant waste without jamming; the output is generally coarser and more heterogeneous. The right choice depends on the type and size of the material to be processed and the targeted output coarseness. For a detailed comparison, see our article: single-shaft or double-shaft shredder.

Position in the line and integrated use

In most recycling plants the shredder is positioned as the first station of the line. It comes after the bale opener or feeding conveyor; if desired, it is integrated with metal separators, belt and conveyor systems. The pre-shredded material is fed to the granulator and washing stages in the next step. This integrated setup both increases line efficiency and balances the load on the downstream machines.

The information on this page is for general guidance; the appropriate shredder type, capacity and configuration are determined according to the project and the material to be processed. For details, you can contact İnan Tech.
