Abstract (en)
[origin: GB2343389A] Granules of plastics material are coated with a mixture of sand and salt grains by tumbling and heating a mixture of grains and plastics granules by passing them along a heated rotating hollow tube 1. The grains and plastics material granules are fed from hoppers 7,8, mixed by rib(s) 6 and heated to a temperature not less than the softening temperature of the plastics granules by a heater 5 . The coated granules are then tumbled and cooled before leaving the rotating hollow tube. The salt grains may then be removed by washing, to form a waste water treatment medium.
