Apparatus for mixing fluent materials.

摘要

A gravity mixer for fluent materials in which material flows downwardly through a column (10, 12, 14) sequentially along a number of helical paths where it comes into contact with multiple perforated flights (28a-g, 32b-g) which divide the material and divert portions onto other flights for combining and mixing with other portions of material in different paths, thus advancing portions of material and retarding other portions and continuously blending the portions as they are brought together during the fall through the column.
