RUBBER FILLER BATCHES IN POWDER FORM - CONTRIBUTION TO THE SIMPLIFIEDPRODUCTION OF RUBBER COMPOUNDS/

The development of a continuous rubber compounding process for the pur pose of saving energy during the production of rubber compounds, is wi thout doubt a great challenge, but also a chance for the rubber indust ry in the near future. One of the conditions is to convert the rubber and filler into such a form that both components lie homogenously dist ributed in an intimate mix. The manufacture of free flowing rubber/fil ler batches in powder form is one of the most promising approaches to the problem. This concept builds on the positive experience gained wit h these materials in the 70's and 80's, thus bringing them into line w ith the present requirements of the rubber industry with respect to ch oice of raw materials, manufacture and mixing technology.
