Abstract:
A process for making granulate of polymeric material, comprising the steps of:plastifying a polymeric material to form a plastic mass;dividing the plastic mass into single plastic strands;pressing the plastic strands in a stream of cooling liquid;shredding the plastic strands in the cooling liquid into granules thereby forming a dispersion;conveying the dispersion of granules and cooling liquid through a first conduit to a separator;concentrating the dispersion through increase of the content of granulate in the cooling liquid by withdrawing a portion of cooling liquid;conveying the concentrated dispersion of granulate and cooling liquid to a dryer along a second conduit which is longer than a length of the first conduit; andseparating the cooling liquid from the granulate in the dryer.
