A worm enters the material into a first flotation tank filled with tap water to separate all the plastic floating sinker by the parties. The PS and PC, respectively 1.06 and 1.29 specific gravity heavier than water and therefore that, according to the principle of Archimedes, sink. Polypropylene, with specific gravity of 0.94 will remain against the surface. The tub has two extraction systems respectively for floating and sinking. The floating, in this case the polypropylene is conveyed to a centrifuge for drying while sinking continue their path in the line of separation. The centrifuge, and further processing, downloading material from the cyclone collection to a pneumatic system that delivers it to a silo pending final packaging. In the next tank, the water is weighed down with the simple salt until a specific gravity of about 1.10 to float the PS (with specific gravity 1.06) and leave the bottom of the PC (with specific gravity 1 , 29). The second bath has the same devices for which the previous system of extraction of floating floats that will manage the PS is transported to a centrifugal drying and subsequent handling. The PC continues its path to a special washing machine by means of a controllable high friction in the presence of water, is able to extract the "contaminant" surface, ie the thin layer of aluminum powder that acts as a mirror reading, spread by means of a special lacquer with various screenprints. The friction generated by the machine allows you to completely remove these materials and return a ground surface of transparent PC ready for reuse after drying in a centrifuge dedicated to this type of product. Text Box: SILOSLa internal handling of materials during the manufacturing process is almost entirely automatic and all stages of the process are controlled by a PLC, together with the control of the density of water, the amount of energy (friction) to be given to washing machine and, of course, for security management.

Our facility has been increased by a system of separation of the material through a highly sophisticated next-generation optical splitter in order to provide a perfect finished product to our customers.
We are then able to market neutral PP, PS and PC neutral crystal perfectly separated from any other material and / or impurities.
operation:
Posted in the hopper, the product to be selected on the vibrating plate moves up to an inclined channel flow. Exit from the chute, the product is controlled individually by the latest generation of CCD cameras. Depending on the signals detected by the optical system, the software controls the pneumatic device that physically divides the product shall be rejected from the one recognized as "certified" that following the fall flow, of course, reaches the discharge hopper. The products to be rejected are deflected by a jet of compressed air emitted by the relevant and directed to the waste disposal basin located on the front of the sorter. In our version with automatic review, the product selected, or the difference from the previous section is conveyed to another section of the same machine to undergo a process of manufacturing the same.
