Abstract

An extruder for feeding finely divided solids. And, in combination therewith, means for using gas in various ways to repulverize the finely divided solids. It lends itself to a procedure for continuously charging finely divided solids with water into a high pressure reactor. The high pressure is inherently contained, and the solids are repulverized for use in a reaction.
