What is the difference between low-speed and high-speed shredding and how it impacts on shredding of waste to energy (WtE)?

The difference among low-speed, medium-speed and high-speed shredding is the speed of the rotor. The slower the speed, the less temperature pass to the material, there's also a smaller chance of damage because allows for dealing with the unshreddable materials safely in the process.

In the same condition, a higher speed has higher capacity; however, the higher speed of the shredder, the higher risk of nonshreddable material being fed through. As a result, higher speed leads to a higher risk of damage incurred to the machine.

Usually, during the preshredding process, we recommend a low-speed and high-torque shredder for a coarse shred of 50-300mm. That way you can process the materials effectively and catch any large contaminants or hazardous objects.

During the fine shredding process, operators could consider using a high speed, which gives as many cuts per minute for small particle sizes of less than 50mm.
