<p>Pellets of PVC are produced by mixing solids from silos 1, liquids from tanks 10 and minor additives in individual bombs 17 from a carousel 18. The mixture is agitated to a temperature of about 95 DEG C and then cooled in a cooler to 60 - 70 DEG C. The cooled mixture is delivered on demand from an intermediate hopper 31 to a kneader hopper 37. Pellets are cooled in a fluidised bed cooler 50 and discharged to a sieve 55. Oversize is recycled along line 70 to the kneader hopper 37. Masterbatch material may be added directly into the recycle line 70 and/or into the kneader hopper 37. <IMAGE></p> |
