ProductVibro Screen for PVC Compounding, Extrusion, Injection moulding and Polymer powder
ManufacturerEta Engineering Services, India
In plastic industry, Eta Vibro Screens are used for following main applications:
1) PVC Compounding / Moulding:
In PVC Extrusion, or Moulding, the compounded material coming from cooler mixer is often containing small lumps, globules or chips which are not completely mixed. Hence it is desirable to sieve the material coming from pneumatic discharge valve of mixer before the material is used by next process of extrusion or moulding. For this purpose, Eta Vibro Screen uses wire mesh of different opening depending upon requirement.
The mixer batch unloads in very short time to siever and is screened as per the screening speed of Vibro Screen. Lumps or chips which are not properly mixed are retained on screen and are discharged from the outlet provided above the screen. Powder which falls below the mesh is discharged automatically and continuously from the outlet provided below the screen. Removal of Lumps.
2) Masterbatch Extrusion / Fillers Compounding:
In master batch or filler compoud production, the polymer strand is cut into required sized granules using Stand Pelletizer / Die face Cutter / Under Water Pelletizer etc. Over and above the required size granules, this stream often contains joined granules, long strands, dust, chips or undercuts. Even in simple extrusion process of making coloured granules, this is often the problem.
Classifier for granules pellets:
For this purpose, Double Deck Eta Vibro Screens with two sieves, are used for passing OK granules and for removing dusting. The material is fed to the center of vibro screen on first screen separates out over sized material like joined granules and discharges the lumps/ large pieces through the TOP outlet. The middle outlet continuously discharges the useful size which is used for further process/ sales. The fine dusting or undercut / chips falls through the lower screen and discharges continuously from bottom outlet.
3) Injection Moulding, Reprocessing Industries:
In Injection moulding industry Sprue, Runner or rejected molded articles are cut in granulator or scrap cutter to smaller size for the purpose of reuse. In granulator or scrap cutter, the fine dust is always generated. This dust, fines or chips may create black spot on moulded product due to charring or heating.
Eta Vibro screens are very effective machine for online as well as offline use to remove / screen out these grindings.
Machine used is normally Single deck machine with wire mesh to retain bigger pieces discharge the dusting. As a result you get granules of acceptable size for reuse in moulding. This type of single deck machines are also popularly used by scrap recycling and reprocessing / reprocessed granules industry.
A double deck machine similar to master batch can also be used to remove very large lumps from grinding process
4) Polymer Powder:
Removes coarse/unground material from powdered / pulverized material for steady powder quality
