Abstract
A mixer and method of using the mixer is disclosed in which a closed chambered vessel capable of both holding pressure and vacuum is charged with a mixture of elastomer and materials taken from the group of tall oil, fatty acids and residues of tall oil production. The charge mixture is heated under pressure without excessive friction heat. After the heating cycle, the mixer atmosphere is evacuated under vacuum, and then the mix is discharged.
Claims15
A method for combining post vulcanized cross-linked elastomers with any of tall oil, fatty acids and residues of tall oil production (hereinafter “oils”) to form a dry liquid concentrate which flows, comprising:
- charging a vessel with elastomers;
- heating the elastomers in the vessel while combining the elastomers with the oils to form a free flowing granular solid mix while the vessel is sealed;
- building the pressure in the vessel during said heating.
