In Brief
Pneumatic conveyors damage plastic granules through abrasion, breakage and static charge at 20–40 m/s airspeed. PHS Magnum transloads big-bags and octabins into silo trailers using gravity only — no screws, vibration, or pneumatics. The covered hall, cleaning sieve and certified weighing ensure contamination-free, documented handover. 20’ and 40’ sea containers received directly on site.
Plastic granules – whether polyethylene (PE), polypropylene (PP), PVC or polyamide (PA) – are sensitive to mechanical damage. Plastics manufacturers pack them in big-bags or octabins to ensure they arrive intact at European processing plants. The problem arises when they need to be transferred into a silo trailer for onward transport.
Why Pneumatic Conveyors Are a Bad Choice for Plastic Granules
Pneumatic conveyors (venturi blowers and compressors) move material using pressurized air at 20–40 m/s. For sand or cement that’s ideal. For plastic granules it’s not:
- Breakage and abrasion – granules hit the pipe walls at high speed. This creates dust that contaminates the batch and can cause quality complaints from the recipient.
- Static charge build-up – friction against steel or aluminium pipes generates electrostatic charges. This is a problem for flammable or discharge-sensitive materials.
- Contamination – if the pneumatic line is not airtight or has not been cleaned, contaminants from previous transports enter the batch.
- Clumping of hygroscopic materials – compressor air contains moisture; for moisture-sensitive materials like polyamide or polyethylene this can cause grain agglomeration.
How We Handle Transshipment at PHS Magnum
We use gravity-assisted manual transshipment with forklift support:
- The big-bag or octabin is lifted and opened; the granules flow by gravity through a cleaning screen (removing clumps and contaminants) into the silo trailer inlet.
- No contact with pressurized metal pipes.
- No electrostatic charging.
- Minimal material losses.
This method is slower than pneumatic – one silo trailer (approx. 25 tonnes) typically takes 4–6 working hours – but it guarantees the product quality demanded by plastics manufacturers.
What Materials Can We Transship?
We transship virtually all granules and bulk materials packed in big-bags or octabins:
- PE, PP, PVC, PA, ABS, PS granules
- Colour masterbatches and concentrates
- Flour and starch
- Filter sands and fine aggregates
- Fly ash and gypsum
- Free-flowing fertilizers
Infrastructure
We have a covered warehouse (weather-independent), forklifts with up to 5 tonnes capacity, and direct silo trailer loading bays. Single-batch capacity: several dozen big-bags.
