Abstract
A continuous mixer of the duplex type which has within a chamber a pair of mixing shafts each with a feed portion, a mixing portion and a discharge portion is disclosed. The mixer includes a weir member provided on the bottom wall of the chamber at a position opposing the discharge portions of the respective mixing shafts, to prevent short-passes of unmelted material.

A duplex type continuous mixer, comprising:
- a casing having an inlet and an outlet at opposite ends thereof and defining a pair of parallel cavities extending between said inlet and outlet;
- a pair of mixing shafts rotatably received in said cavities and each having a feed portion, a mixing portion, a discharge portion and an annular groove separating said mixing and discharge portions;
- and
- a weir member projected upwardly from the bottom walls of said cavities at a position corresponding to said annular groove of said mixing shafts so as to prevent the short-passes of unmelted materials, wherein the cross sectional profile of the top surface of said weir member is identical to the cross-sectional profile of said bottom walls of said cavities.
