Sorting

The main idea behind any recycling and washing plant for plastics is to be able to obtain an outgoing product the more washed and dried, but above all HOMOGENEOUS.

The homogeneity of the outgoing product depends on the quality of the separation process of the different kinds of plastics, performing by using a very simple principle, that is the FLOATATION, which works on the SPECIFIC WEIGHT of the different kinds of materials.

Materials with specific weights or upper or lower to the one of water (fixed as = 1, as a reference) usually aren’t compatible and must for this be separated in order to be reused separately later.

ITALREC designs and manufactures FLOATATION TANKS which allow to separate, and then recover, both kinds of plastics, that means both the floating ones (SP < 1, usually POLYOLEFINIC basis) and the sinking ones (SP > 1, STYRENIC basis, but also PVC or PET).

The technical concept is practically the same but working in the opposite way, allowing the recovery one of the floating plastics, the other of the sinking ones.

Particular measures have been taken for what concerning some technical modifications, included tanks dimensions, walls inclinations, number and type of rolls, palettes design, unloading auger diameters.

All this for better granting both the longer time of residence possible in the water, avoiding at the same time possible jamming, and the maximum and the more efficient handling of the product itself. All this gives as a result an HIGHER GRANTED EFFICENCY IN THE SEPARATION, and so a FURTHER WARRANTY OF QUALITY IN THE OUTGOING PRODUCT.


EL PREFLOATATION TANK

Especially when materials in bales must be worked, it’s suggested to use, even combined with other pre-treatment machines, a PREFLOATATION TANK. It is the ideal machine for eliminating, by using the specific weight of the materials themselves, all those polluting elements which can, not only affect the quality of the product, but even cause damages on the following fast machines in the plant (striking example the presence of heavy metals inside the bales).

By using an ELLIPTIC COMB instead of the classical rolls of standard floatation tanks avoid jamming and blocks caused by the material, considering that it can usually be passed into the tank without any previous substantial shredding treatment.


VLPE FLOATATION TANK

It allows the recovering of the floating plastics which are extracted on the top of the tank by means of an auger, while sinking plastics and wastes are collected on the bottom of the tank and conveyed and extracted by means of another auger.

Particularly indicated for: POLYLEFINIC BASIS PLASTICS (PP, HDPE, LDPE, LLDPE) + EPS


VLPET FLOATATION TANK

It allows the recovering of the sinking plastics which are extracted on the bottom of the tank by means of an auger, while the floating ones are moved towards the top and extracted by means of another auger.

Equipped with a trap in the entrance for eliminating the maximum of the heavy wastes, in order not to pollute the sinking plastics to be recovered.
Particularly indicated for: STYRENIC BASIS PLASTICS (PS, ABS) + PET + PC + CHARGED PLASTICS
