Liquid Separation Plant

Supplier: Brentwood Recycling Systems

The solution for separation of liquids from filled plastic bottles.


Plastic bottles – either filled or empty – are placed into the safety hopper using a forklift with tippler arrangement (other systems on request). This Safety Hopper is fitted with a pneumatic sliding door arrangement to ensure material is not ejected from the hopper during shredding and that access to the shredder cutting chamber is restricted while the system is running.

At the base of the hopper is the Brentwood AZ15WL shredder - the heart of this unit - which feeds the shredded material into a specially designed screw feeder that allows any entrapped liquids to be released before discharging the shredded material into a bin located at the base of the screw feed discharge. Liquids released during the shredding and screw agitation stages are gravity fed to discharge points along the screw housing. These liquids can be discharged into a bund or connected to a pump out system for removal and storage.

Both the shredder and screw feed unit are fitted with a high pressure water blasting system that is part of the integrated system to remove materials from the shredded plastic. The water blasting system also cleans the shredder cutters while shredding to ensure optimal performance of the system.

This system also makes end of shift cleanup a simple and quick procedure as no covers need to be removed and no operator needs to climb onto the unit to clean the shredder and screw. The LS15P will process plastic bottles up to 3 litre at an expected rate of 30 tons per hour (including liquids).
