Abstract

A mixing and extrusion machine for tire sealant materials of the type comprising: a dump extruder equipped with conical converging twin screws located in a batching chamber, said chamber having a low pressure feeding area and a high pressure ducted area; a removable blind flange for temporarily sealing the outlet of said batching chamber so that said material is forced to recirculate between said duct area and said feeding area within said batching chamber, said chamber thereby also acting as a compounding chamber; and an inlet port located in the high pressure ducted area, the inlet port capable of introducing a diluent during mixing of a tire sealant material.
