WANROOETECH’s agricultural LDPE film recycling machine is specifically engineered for recycling agricultural films and other films containing large amounts of sediment, dirt, and organic contamination. This LDPE film recycling line efficiently processes agricultural waste films including mulch films, greenhouse films, and tobacco mulch films. The system delivers high crushing efficiency, advanced sand removal, thorough cleaning, and effective drying capabilities. Each integrated LDPE agricultural film recycling solution is customized according to the practical needs of customers and adapted to the specific conditions of the customer’s region, ensuring optimal performance and return on investment.
Why recycle agricultural LDPE film?
LDPE film is mainly composed of high-pressure low-density polyethylene, which is chemically stable, resistant to alkali and organic solvents, and very difficult to degrade under natural conditions. LDPE film can be recycled, either into oil by high-temperature cracking or into plastic pellets after cleaning, so it is necessary to recycle LDPE film.
How to recycle agricultural LDPE film?
How Does the Agricultural LDPE Film Recycling Process Work?
Agricultural LDPE film presents unique recycling challenges due to extremely high contamination levels. The typical film contains large quantities of sand, mud, straw, and organic residue from field use. The WANROOETECH LDPE film recycling line addresses these challenges through a carefully designed multi-stage process:
Collection & Pre-Treatment Stage Waste LDPE film is collected in large rolls and bales. The material first passes through a plate chain conveyor belt to the bale opener, where initial sand removal occurs. A trommel screen further separates loose sand and soil. The pre-shredder then cuts the material into 50-150mm pieces, with another trommel stage removing additional sand. This pre-treatment is critical because high sand content significantly shortens crusher tool life and degrades washing quality.
Intensive Desanding Stage The shredded film enters two sequential desanding machines. The first desanding machine (screen aperture 12-15mm) removes the majority of remaining sand and soil, with water injection to enhance separation. The second desanding machine provides final fine sand removal, ensuring the material entering the washing stage has minimal abrasive contamination.
Washing & Cleaning Stage The desanded LDPE film enters a wet crusher for fine crushing with water injection, which provides simultaneous pre-washing. The crusher bottom is equipped with a figure washing machine that shakes out sand and dirty water from the material. The crushed film then enters a powerful friction washing machine specifically designed by WANROOETECH for film sand removal and cleaning. This machine operates with full water immersion for maximum contamination removal. Finally, the cleaned film enters a sink float separation tank for rinsing, where remaining light contaminants are separated from the plastic.
Dewatering & Drying Stage The rinsed film is conveyed to an extruder or screw press for mechanical dewatering, removing the majority of water content before thermal drying or direct pelletizing.
Final Processing Stage Depending on the customer’s requirements, the dried clean LDPE film can be processed into plastic pellets using a squeezing pelletizing machine, or fed into a high-temperature cracking system for oil production.
Agricultural LDPE Film Recycling Process:
Agricultural LDPE film recycling washing and high-temperature cracking to oil:
Plate chain conveyor – bale opener (the size of the material is very large 300mm or more, a lot of sand and soil removal) – conveyor belt – trommel (to remove sand or soil) – pre-shredder machine (the size of the material 50-150mm, another step to remove sand) – conveyor belt – trommel (to remove sand or soil) – conveyor belt – desanding machine 1 # (to further remove sand or soil, you can add water) (the screen aperture can be larger such as 12-15mm) conveyor belt – desanding machine 2# (to further remove sand and soil) – plastic squeezing machine (to increase the density of plastic film, to facilitate the next step of high temperature cracking)
Agricultural LDPE film recycling washing and squeezing pelletizing machine:
Plate chain conveyor – bale opener (discharging size is 300mm or more, removing sand and soil in large quantity) – conveyor belt – trommel (removing sand or soil) – pre-shredder machine (discharging size is 50-150mm, removing sand in another step) – conveyor belt – trommel (removing sand or soil) – conveyor belt – desanding machine 1# (further removing sand or soil, water can be added) (The screen aperture can be larger such as 12-15mm) conveyor belt – desanding machine 2# (further removal of sand and soil) – washer machine – low-speed friction washing – plastic squeezing pelletizing machine, etc!
