Description

Line start with a bale breaker. A perforated rotating trommel is placed at the beginning of the line. Trommel removes heavy particles such as stones or sand.

A sorting conveyor is placed next to trommel. PET bottles are presorted manually. Foreign matters, particularly PVC bottles are removed by experienced workers. At this stage color separation is done as well. (An automatic sorting system can be placed instead of manual sorting.) Loading conveyor feeds PET bottles in a regular manner to crushing machine.

Digital dosaging pump with pHmeter keeps pH level of the solution in certain level ensuring washing action is effective all of the time. Two hot washing basins are located at the line which make operation continuous.
PET material which is coming out of washing unit enter into neutralizing unit. Neutralizing unit removes washing chemicals ensuring PET flakes are free from chemical contamination. Vertical separator removes dirt and water from PET flakes and conveys flakes to third float sink pool.
Final sink-float pool removes remaining caps and label residues while rinsing material.
Vertical separator remove excess water and then centrifuge separator removes water from PET flakes bringing down humidity level below 1%. In this stage a digital flake sorter can be placed optionally to separate different colour flakes. At the end of the line, PET flakes are transferred by a blower to bagging silo. Stored into big bags, PET flakes would be ready for shipment.
