ABSTRACT:
A mixing head for thoroughly mixing and uniformly dispersing a dry filler material within a single liquid or a reactive mix. Dry filler is supplied to the compression chamber of the mixing head. A compression auger is mounted in the compression head is driven by a first drive shaft and compresses the dry filler. The speed of rotation of the compression auger is altered in response to the relative pressure of the dry filler within the compression chamber as measured by a pressure sensor. Air expelled from the compressive dry filler is removed through a port in the compression chamber. The compressed dry filler is conveyed to the mixing chamber of the mixing head. The mixing element is rotatively mounted within the mixing chamber for thoroughly mixing the dry filler with the liquid components. The mixing element is driven by a second drive shaft and can be driven in an opposite direction of rotation from the compression auger. The pitch of the flights on the mixing element can be opposite that of the pitch of the flights of the compression auger.
