Abstract
A method for agglomerating and dewatering elastomeric material having a relatively high water content wherein the elastomeric material is fed to a pair of counterrotating pressing rolls with a tight nip opening. The elastomeric material is drawn through the nip opening and compacted and dewatered therein. The method of the present invention produces at least a doubling of the particle size of the feed material and a reduction in the water content of the feed material in the range of 30 to 80%.
