The mixer consists of an inclined auger trough, pos. 6, in which the mixer auger,
pos. 3, is placed. The mixer auger is driven by a shaft gear, pos. 2, on which the
motor, pos. 1, is mounted. The auger trough is mounted with a superstructure,
pos. 7, equipped with an inspection/cleaning door, pos. 4, and an inlet door for
filling, pos. 5.
The mixing is undertaken by a heavy, slowly running auger.
The components to be mixed can be added through the mixer top or lower filling
door. Material addition from a hammer mill is normally done through the mixer
cover via a cyclone. Concentrates are added by means of one or more augers
that can be connected in the mixer cover.
Addition of liquids, if any, is done after adding all dry components, and with the
mixer in operation.
Liquids are added at the top of the mixer through piping or hose lead some
distance down into the mixer.
Mixing the material:
The material is conveyed by a strong auger into the upper end of the mixer
where the mixer is designed in such a way that the material is pressed up like a
molehill and then glides back to the lower end of the auger. This gives a careful
and homogeneous mixing procedure.
