1. A method of preparing a composite, comprising:
(a) charging a mixer having one or more rotors with at least a solid elastomer and a wet filler comprising a filler and a liquid present in an amount ranging from 15% to 65% by weight based on total weight of wet filler;
(b) in one or more mixing steps, mixing the at least the solid elastomer and the wet filler to form a mixture, and in at least one of said mixing steps conducting said mixing wherein the mixer has at least one temperature-control means that is set to a temperature, Tz, of 65° C. or higher, and removing at least a portion of the liquid from the mixture by evaporation; and
(c) discharging, from the mixer, the composite comprising the filler dispersed in the elastomer at a loading of at least 20 phr with a filler yield loss of no more than 5%, wherein the composite has a liquid content of no more than 10% by weight based on total weight of said composite.
