Abstract
In a process for making plastic granulate, a polymeric material is plastifyed into a plastic mass which is divided into single plastic strands. After pressing the plastic strands in a stream of cooling liquid, the plastic strands are shredded in the cooling liquid into granules, thereby forming a dispersion which is conveyed through a first conduit to a separator. The dispersion is concentrated in the separator by withdrawing a portion of cooling liquid, and subsequently transported to a dryer along a second conduit which is longer than the length of the first conduit. In the dryer, the cooling liquid is separated from the granulate.
