Four Shaft Shredders

Four Shaft Shredders

Four Shaft Shredders are suited for applications such as electronic scrap, tire recycling, alternative fuel production, and reduction of contaminated materials where uniform, small to medium particle size is desired. They are ideal to shred and recycle very long and oversized wood waste such as mature timber, long boards, pallets, packaging, and cardboard of any kind. Four-shaft shredders are mainly used in the wood processing industry.

Operation Principle

Materials are fed through the hopper of the four-shaft shredder to the cutter. The ripping teeth of the cutting discs powerfully grab and shred the material.

The clearing plates push the shredded material through the clearance between the main cutters.

The material is then discharged through the screen below the cutter.

Depending on the composition of the material to be shredded and the diameter of the holes in the screen that is used, the throughput rate ranges from 300 to 2,000 kg/h. Because of the shafts' extremely low rotational speed of about 25 rpm, sound level is only about 76 dB(A). The machines are equipped with automatic overload protection and a reverse switch.
