WASHING AND SEPARATING TANKS
This type of machines is used for the separation of materials having different specific weights, and especially to remove part of the heavy contaminants from polyolefin plastics.
The principle used is that of the flotation in a fluid which can be water or a liquid mixture.
There are several models of tanks produced by PRT Service & Innovation.
Characterized by a double auger system for the extraction of the sinking material, handling rotors and draining auger for the extraction of the floating material.
These are simpler models, with single inclined screw conveyor for the extraction of the sinking material, handling rotors and possibility to install or not a draining screw for the extraction of the floating material.
These tanks are used for the prewash of highly polluted thermoplastic film, coming from shredding, for the rapid separation of iron and stones, the extraction of which is made through a double guillotine valve.
