Screw mixer
PFT LOTUS XL
The revolutionary mixing technique with decisive
advantages.
With its significant advantages the new horizontal
screw mixer PFT LOT S XL revolutionises mixing
technology.
The sturdy rubber mixing tube has already proved
itself in easy and quick cleaning of the PFT mixer.
nique is the new, revolutionary dosing and
mixing shaft, manufactured as a single unit without
a middle axle.
This type of construction is pointing the way:
No more deposits adhering, and the cleaning is
easier and faster than ever before.
The PFT LOT S XL has been developed for the
use of silo and container material: it mixes
continuously and fully automatically all premixed
dry lime/cement based mortars up to a grain size
of 8 mm.
An additional important advantage is the turnable
dosing segment. If replacement becomes necessary
due to wear, the segment can be turned 180° for
double use.
