Bales opener/bale breaker:

The bale breaker is driven by motors with slow rotation 

speeds. 

The shafts are provided with paddles that break the 

bales and allow the bottles to fall without breaking.

Dry separation/ Trommel:

This machine allows the removal of many of the solid 

contaminants (sand, stones, etc.), and represents the 

first dry cleaning step of the process.

It is an optional piece of equipment, the trommel is a 

slowing rotating tunnel lined with small holes. 

The holes are slightly smaller than the PET bottles, 

so small pieces of contamination(such as glass, 

metals, sand, stones, etc.) can fall through while the 

PET bottles move onto the next machine

Label remover/ Delabeler:

REGULUS has designed and developed a system that 

can easily open the sleeve labels without breaking the 

bottles and saving most of the bottles necks.

The bottle material is input from the feeding port 

by the conveyor belt. 

When the blade welded on the main shaft has a certain

 included angle and spiral line with the center 

line of the main shaft, the bottle material will be 

transported to the discharge end, and the claw 

on the blade will peel off the label

Plastic granulator/wet grinding:

Through the granulator, PET bottles are cut into smaller 

pieces to achieve the required size distribution for the 

washing sections that follow. 

Normally, crushing flakes size between 10-15mm.

At the same time, with water constantly spraying into 

the cutting chamber, a first washing process is 

performed in this section, eliminating the worst 

contaminants and preventing them from entering 

the downstream washing steps.

Washer tank/ Sink and float separation:

The target of this section is to remove any polyolefins 

(polypropylene and polyethylene labels and closures) 

and other floating material and to conduct a secondary 

washing of the flakes. The heavier PET material will sink 

to the bottom of the flotation tank, from 

where it is removed.

A screw conveyor at the bottom of the sink 

float separation tank moves the PET plastic 

to the next piece of equipment.

Hot Washer System:

Hot washed PET flakes are of higher value because this 

process dissolves glues(used to glue labels onto the 

bottles) and leftover beverages/foods that are difficult 

to remove in a cold wash process. Although you can 

just use water in the hot washer system, 

adding washing agents can added for better results

Dryer:

Centrifugal dewatering machine:

Initial mechanical drying through a centrifuge allows 

the removal of water deriving from the final rinsing 

process.

Thermal dryer:

The PET flakes are vacuumed out of the dewatering 

machine into thermal dryer, where it travels down 

a series of stainless steel tubes mixed with hot air. 

So the thermal dryer properly treats the flakes with 

time and temperature to remove surface moisture.

Fines separation/Dust remover:

It is an elutriation system, which is used to separate 

remaining labels, having dimensions close to those 

of the PET flakes size, as well as PVC, PET film, 

dust and fines.

Product silo:

A stotage tank for the clean and dry PET flakes.

PET flakes pelletizing machine:

For the most part, PET flakes are used to produce 

using product directly.

There are also some customers requiring plastic 

pelletizing machines.
