A step-by-step plant workflow for removing silicone, rubber and elastomer contamination from plastic regrind — from feed prep and density pre-sorting to friction separation, second-pass recovery, and verifying you hit a sub-2% rubber residue.
Silicone, rubber, and rigid plastic constantly end up mixed in recycling streams — and they are not the same material. This guide explains how they differ, why density sorting cannot tell them apart, and how a recycler actually separates them to sell clean, single-resin flake.
Magnetic separators catch ferrous metal; eddy current separators throw non-ferrous metal forward. They are almost always used together, not against each other. This guide explains the decision in concrete terms — by feed type, contamination, recovery value and order in the line.
PE and HDPE — not PVC — drive the largest share of the plastic pulverizer market. This guide covers rotomolding powder for pickleballs, tanks and kayaks, plus how the same machine handles PP, PS, ABS, EVA and PA with the right disc and cooling configuration.
A practical pillar guide to pelletizing plastic—the full six-stage process, how strand, water-ring, and underwater systems differ, and a material-by-material adaptation matrix covering PE film, PP raffia, HDPE rigid, PET, PVC, PS, EPS, and ABS. Built for recycling plant decision-makers who need to validate scope before issuing an RFQ.
Learn how to choose and operate a PVC pulverizer for your plastic recycling line. This guide covers rotor designs, cooling systems, and how to achieve consistent 20-120 mesh plastic powder from rigid PVC pipes and flexible scrap.
