Plastics compounders and rubber processors handle powders such as PVC resin, stabilisers, fillers, rubber chemicals and masterbatch fines. A vibro sifter removes lumps and contaminants before mixing and grades powders to a consistent size so they disperse evenly.
Applications
- Screening PVC resin and dry-blend compounds.
- De-lumping stabilisers, accelerators and antioxidants.
- Removing fines from pellet and granule feeds.
- Sifting fillers such as calcium carbonate.
Considerations
- Polymer powders can build static – the machine should be earthed.
- Light, fluffy powders need generous screen area.
- Some rubber chemicals are sensitive to heat and moisture – store and sift dry.
- Fine polymer dust can be combustible – follow your area classification.
For most plastics and rubber duties a single deck vibro screening machine is sufficient; use a double deck to remove both lumps and fines.
