Abstract
Methods, systems and agglomerators for recovering mixed multi-plastic and natural fiber are described. The systems, methods, and the agglomerator operate at low temperatures to avoid degradation of the plastic film. The agglomerator includes cutting discs that are adjustable.
Claims20
A system for the recovery of mixed multi plastic and natural fiber materials, comprising:
- an agglomerator, the agglomerator comprising:
- a cutting disc compartment configured to receive scraps of mixed multilayer plastic film materials;
- the cutting disc compartment comprising a stationary disc plate and a rotating disc plate;
- a motor configured to rotate the rotating disc plate;
- a main control panel;
- a liquid chiller, and the main control panel in communication with the liquid chiller;
- the liquid chiller fluidly connected to the stationary disc plate, the liquid chiller configured to cool the stationary disc plate, wherein the main control panel modulates a level of cooling provided by the liquid chiller to the stationary disc plate to maintain a temperature differential between the rotating disc plate and the stationary disc plate and to maintain a temperature of the mixed multilayer plastic film materials below a melt index of the mixed multilayer plastic film materials;
- a feeding host;
- an agitator to receive the scraps of mixed multilayer plastic film materials, the agitator positioned over the feeding host;
- the feeding host positioned to direct to the scraps of mixed multilayer plastic film materials to the cutting disc compartment;
- the cutting disc compartment configured to agglomerate the scraps of the mixed multilayer plastic film materials into agglomerated particles;
- a cutting space is formed between the stationary disc plate and the rotating disc plate, wherein the stationary disc plate includes a central opening, an end of an auger passes to or into the central opening and directs the scraps to or through the central opening, wherein the central opening leads to the cutting space between the rotating disc plate and the stationary disc plate;
- a shredder configured to receive the agglomerated particles from the agglomerator;
- and,
- the main control panel to control the shredder and the agglomerator.
