The recycled polyolefin plant is composed by the following phases:

– PRE-TREATMENT OF SAMPLES:

The samples are cutting to completely homogenize their size and to achieve the maximum performance in the subsequent contraction process. 

– HEAT TREATMENT

The heat treatment of the polyolefins is carried out in a rotating drum with heating system. The parameters of temperature and speed drum is controlled to optimize the process. At the end of this process, there are two strems: Polyolefins which have been deformed by heat (low-PP) and polyolefins which are not deformed (high-PP).

– SEPARATION OF POLYOLEFINS:

The separation between the two streams are carried out by the vibrating pneumatic sorter, where by the vibration and airstreams, the different blends of polyolefins are sorted, depend of the contraction that it has been carried out previously.
