Two types of feeding systems are available:
Pre-mixing processes with volumetric feeders

The ingredients are weighed separately according to the recipe
All materials are then placed in a high speed mixer for 5 to 10 minutes
Discharge of the material into a screw loader
Loading the material into the hopper of the volumetric feeder
Feeding in stages with loss-in-weight feeders: (automatic and more accurate)

Place the material into each trough on the floor
The vacuum loader or liquid pump conveys each component to the storage bin.
The raw material will automatically fall into the loss-in-weight feeder. The feeding system will feed the material into the extruder individually, according to your recipe settings on the HMI.
There are three types of loss-in-weight feeders for liquid, granular and powder materials.

Some additives are sensitive to shear, so the best process is to feed them in stages - via a side force feeder into the fifth barrel of the extruder. The side force feeder is fixed with a water-cooled jacket for melting additive powders with low temperatures.

 

 

One extruder should be able to produce many types of additives. It therefore requires a quick-cleaning type of stranded die plate to change the formulation.

The bulk density of the additives is relatively low, so the output depends mainly on the feed capacity rather than the torque of the main motor. Our twin-screw extruders are therefore better suited to this process.
