Four Shaft Shredder, 4 Shaft Shredding Machine for Sale

The four-shaft shredder is a shear type shredder, slow running makes it powerful and extraordinarily quiet in operation. They are particularly suited to shredding long, bulky items.

In general, four-shaft shredders are used for more difficult tasks, such as reducing large volumes of material to a small and uniform size in a single pass, while maintaining good throughput. The function of the two cutters above the four-shaft shredder is to clean the shafts below and at the same time provide a certain amount of shearing force.

Four Shaft Shredder Working 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 800 to 15,000 kg/h. Because of the shafts' extremely low rota- tional 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.
