Abstract

Procedure for the manufacture of small and uniform rubber lumps in a narrow granulation range, characterized by the fact that an acid coagulation mixture is made alkaline by means of the addition of a weak alkaline hydroxide solution, by the fact that it is dehydrated by centrifugation, due to the fact that the spin residue is dried in a parallel stream of hot inert gas and separated from the powder and finally dries in a diffusion zone and due to the fact that the dry product without powder is crushed up to a maximum gram size of 2.5 mm.
