Double Shaft Shredder Blade
Multi-shaft shredder blades, also known as claw blades, are designed to be installed on dual-shaft or four-shaft shredders, based on various companies’ designs. They are typically categorized into 3-claw, 8-claw, and 12-claw shredder blades, and are used for crushing, tearing, and compressing materials to reduce their size. These blades are applied to the shredding of waste plastics, rubber, wood, and other large-volume materials.
