Abstract

Rubber pellets are coated with an anti-tack material. The anti-tack material may be comprised of a metallic stearate, such as magnesium stearate. The coated rubber pellets are loaded on to a rotational conveyance mechanism that rotates at a speed and radial amount to provide an interaction time between the rubber pellets and the anti-tack material. The coated rubber pellets may then be dried in a centrifuge dryer having a plurality of angled fins extending from a rotational shaft.
