ABSTRACT:
The present invention embraces method and apparatus for processing heat-softened mineral material. Heat-softened mineral material flows from a supply through a passage, such as the passage in a flow block member or a bushing block member, into a bushing. The heat-softened material is thermally conditioned in the passage by a heat pipe which is thermally isolated from the passage such that the heat pipe does not substantially act as a heat sink from the material to the passage.
