ABSTRACT:
The apparatus is for the continuous mixing of rubber like polymers with chemical additives to form a homogeneous compound, using minimum unproductive work, such as mixing already mixed material, or massive batch blending to correct lean and rich mixtures previously produced. The apparatus consists of a feeding means adapted to continuously and uniformly advance baled polymer into a machine hopper provided with a multi-purpose rotor, adapted to cut the advancing bale into shreds, in the presence of the chemical additives, mix the shredded polymer with the chemical additives and advance the resulting compound into a continuous mixing means. Mixing with minimum waste motion is expected to produce a superior compound not possible to obtain with present day production equipment.
