Abstract:
A mixer system for combining material of post-vulcanized cross-linked elastomers with any tall oil, fatty acids and residues of tall oil production (collectively â€œoilâ€ ) to form a dry liquid concentrate which flows, comprising:a tank having a mixing chamber, said tank including an oil heater having a heating oil closed loop system to heat the contents of said mixing chamber; a mixer mounted in said tank and extending into said mixing chamber, said mixer including at least one shaft seal sealing said mixing chamber; a feed port mounted on said tank and adapted to feed the elastomers into said mixing chamber; a vacuum pump mounted to said tank adapted to evacuate said mixing chamber of vapor and gas; a discharge port mounted on said tank and adapted to discharge the material from said mixing chamber; a pump to feed the oil to said mixing chamber; and a pressure controller to select pressure maintenance of vapor and gas resulting from heat from said oil heater acting on the material in said mixing chamber and vacuum for evacuating vapor and gas from said mixing chamber.
