Two-shaft shredders are used for size reduction of most materials. The shredders utilize two counter rotating shafts with close tolerance cutters that shear products into strips of uniform widths. Shred width matches the thickness of the cutters. Hooks on the cutters help pull material into the cutters and limit the length of the shredded pieces.
The shafts of two-shaft shredders rotate at slow speeds, typically 15-35 rpm. Slower rotation requires greater gear reduction and provides greater torque yielding higher cutting force. Faster rotation allows for faster shredding but at the expense of cutting force. Proper motor sizing balances cutter force requirements with production requirements.
The ShredRecycling is the leading manufacturer for size reduction machines and systems for the waste management and recycling industry.
ShredRecycling Double Shaft Shredder Design
This heavy duty and compactly built machine is designed for the special requirements of modern recycling operations. Excellent accessibility to the cutting chamber by means of large front doors. The rotor knives are screwed on, easily exchangeable and can be re-sharpened many times.
The massive flange bearings made out of solid steel are laterally centered in the housing. The safety devices are in compliance with the current machine builders directives.
