How the single-shaft shredder works
A hydraulic ram forces the material against the single shaft rotor grinder which produces consistent sized particulates that fall through the screen.
Single-shaft shredders comprise an amp-controlled hydraulic ram, which moves the plastic purging or part to be reduced against a single cutter shaft, rotating
relatively slowly, at about 100 to 125 rpm. This low-speed, high-torque shaft has precision, four-point cutters embedded in it, which shear the material against a bed knife (counter-knife) and feed the resulting ‘scissor-cut’ granules through a screen of a size predetermined to provide granulate of the desired size.
The cutters provide an angled cut against the profiled bed knife, cutting like scissors.
A screen is used to determine of the resulting particulate
altered to provide granules of between 3/8 and 5/8, or eve
Small Lump Shredder
A newly developed small lump shredder of Harden is unveiling recently, which belonged SS series single-shaft shredders come equipped with a tangential infeed to eliminate the need for a hydraulic feeding system.
Small Lump Shredder Applications
Our sall lump shredder especially designed for processing the thicker sections of injection, blow molding flash and extrusion mold startup purge in house recycling.
Our Small lump shredder can shred:
- Small lumps(plastic lumps, aluminium lumps)
- Hollow moulds
- Head waste and purges from injection
- Blow molding processes purges
- Extrusion purges
and so on…
The material after shred with our small lump shredder can be processed further in a granulator to be reintroduced into the production process immediately.
Our small lump shredder also can be used to reduce size of sensitive products or to recycle small batches of low volume products to avoid contamination of the main product line.
