Plastic recycling lines COMPAC

The COMPAC regeneration lines represent the most advanced technology in the market. They are highly flexible and able to recycle most types of plastics from different forms: films, ground and densified materials, rolls.

This type of line is available in different models depending on the production capacity. Every line can be customized upon request with additional components to satisfy the customers’ requirements.

The typical composition of the line:

conveyor belt with metal detector
cutter-compactor
extruder
filter
underwater pelletizer TI or water ring pelletizer TDA
panel with touch screen

LINE	ENERGY CONSUMPTION (KWh/Kg)	PRODUCTION CAPACITY (Kg/h)*
GM50	0,25 ÷ 0,30	50-150
GM65	0,25 ÷ 0,30	150-260
GM90	0,25 ÷ 0,30	250-500
GM105	0,25 ÷ 0,30	400-680
GM125	0,25 ÷ 0,30	600-950
GM160	0,25 ÷ 0,30	1000-1400
GM180	0,25 ÷ 0,30	1500-2000
GM210	0,25 ÷ 0,30	2000-2800

* The capacity refers to LDPE, and can vary depending on the density of the material, degree of pollution, print and humidity percentage.

Advantages of Compac lines

ECOTRONIC System

The ECOTRONIC system created by Gamma Meccanica, applied to the cutter-compactor, optimizes the speed of the cutter-compactor in order to maintain the requested temperature without the use of water.

Feeding screw

It pushes the material (especially low bulk density) into the extrusion screw.
The screw speed is automatically adjusted to keep constant the extruder production.

Degassing system

The degassing system eliminates the gas produced during the extrusion and prevents the beginning of defects in the granule such as “air bubbles”.

By-pass

The by-pass allows the installation of the dosing unit for granules, compacted and ground materials with higher bulk density, directly feeding the cutter-compactor as a single material or in combination with the material coming from the belt or from the nip roll system.

Specific applications of the Compac lines

Lines for PET recycling

Lines for PET recycling
Great efficiency, productivity and energy savings

This type of the line has been specially designed for PET recycling.
The PET lines are generally composed of conveyor belt, cutter-compactor, extruder, screen changer and underwater pelletizer TI.
The most important aspect of regeneration in this case is the need to limit the drop of the intrinsic viscosity value (IV). This value determines the mechanical performance of the material. The lines proposed by Gamma Meccanica S.p.A. allow for treating the material limiting the fall of IV.
These lines are designed for the regeneration of PA as well.
PET recycling lines are available in different models based on production capacity.

Recycling lines biodegradable plastics

Biodegradable plastics started to be developed in the early ’90s, initially by adding corn starch to the plastic materials.

Gamma Meccanica S.p.A. has worked for years with manufacturers of biodegradable materials to develop lines more and more advanced, using the expertise and collaboration of industry experts.

The acquired know-how has enabled the company to be a leader in the recovery of biodegradable plastics.

For instance, the recycling of PLA, that is a part of biodegradable plastics, is a big challenge since, if not properly recycled, this material degrades and is no longer suitable for reuse. Another increasingly popular material is biodegradable PE to produce shopping bags. Gamma Meccanica S.p.A. offers the best solutions for the recycling of waste deriving from production also for these biodegradable plastics.
