Separating different plastics.

 

 

DRY - Air classifiers - Mechanical classifiers - NIR (Near Infrared Rays) - Laser spectral analysis - Polarized light - UV light - Colours by fluorescent light - Electrostatic - By melting or softening point - Other methods

WET - Sink-float tanks - Hydrocyclones - Sink-float by preferred solvent absorption - Sink-float by hydrophobicity - Froth flotation - Selective dissolution

 

As you can see, separation methods are very many and each one performs well for a specific condition of the scrap you are handling.

 

Another aspect of all this is, like we are saying almost everywhere is the cost related to each method.

 

Once again, it depends a lot by what you have and where you're trying to get to.

 

One system can do very well at a limited cost if you're not looking to sell your product to NASA, otherwise you should install and run one, or more than one system to get the quality you are looking at.

 

But it's going to cost you money.
