<p>A mixture of unlike particulate solids is dispersed in liquid nitrogen to form a slurry. The slurry is then subjected to shear and impact forces of sufficient intensity and duration to break up agglomerates, to comminute at least the larger particles, and to obtain a randomly mixed homogeneous suspension. The suspension is thereafter stabilized by removal of liquid nitrogen to form a paste or powder which may be further processed into shapes by extrusion or molding. One preferred embodiment utilizes a batch-to-continuous process for the compounding of rubber with carbon black and other additives.</p> |
