Plastic Recycling machine for waste HDPE film(lithium battery separator film)
In the production process of lithium battery separator by hydrometallurgy, a large amount of offcut materials (HDPE ultra-high molecular weight polyethylene) will be produced. These offcut(HDPE waste film) can be recycled for pipes, modified plastics and other products, with high utilization value. During the processing of these products, the offcut materials shall be granulated before use. Due to the low melt flow rate of UHMWPE or UHMWPE, extrusion processing is difficult. PURUI provides a new method for degradation and recovery of ultra-high or ultra-high molecular weight polyethylene waste. This method has a simple recovery process, which can be used to degrade and recover ultra-high or ultra-high molecular weight polyethylene in an environmentally friendly and efficient manner, making the polyethylene waste after degradation have good processability, thus realizing the recycling of offcut materials, with good economic benefits.
Plastic recycling line is to break the molecular chain of ultra-high or ultra-high molecular weight polyethylene (UHMWPE) by crushing the film (i.e. the leftover material containing ultra-high or ultra-high molecular weight polyethylene) and then feeding it to the extruder, and then melt extruding under the specific high temperature and the shearing action of the extruder screw, so that the molecular chain of UHMWPE or ultra-high molecular weight polyethylene can be broken, thus having high temperature shearing fluidity and easy processing, realizing resource recovery and reuse, and saving enterprise costs.
Plastic recycling steps:
(1) Crush: crushing HDPE waste film as 30mm by plastic crusher machine and then feeding into agglomerator by belt conveyor.
(2) Extrusion: extruding under the temperature between 160 to 250℃, rotary speed as 60-150rpm, L/D as 30-50
(3) Granulation/pelletizing: melting and extruding materials are cutted by underwater cutting system, final pellets as 2mm
(4) Dryer and collection: after dryer and collecting by silo, the final pellets melt flow about 0.83-1.31g/10min

Simple process, low cost
PURUI’s granulation line can realize the recycling of waste materials of ultra-high or ultra-high molecular weight polyethylene, i.e. offcut, and directly use them for the processing of downstream pipes, modified plastics and other products, solving the problem of processing difficulties with traditional methods; In addition, there is no chemical component added during the recycling/granulating process, which will not cause secondary pollution and will be more environmentally friendly; It be achieved the recycling of waste resources, saves costs and has huge economic benefits.
The granulation equipment and recovery method designed by PURUI effectively degrade and recover UHMWPE. The material can melt and flow, and can be re granulated. The material has high mechanical strength.
A plastic recycling and granulating machine is a type of equipment used to recycle plastic waste into granules or pellets that can be reused in manufacturing new plastic products. The machine typically works by shredding or grinding the plastic waste into small pieces, then melting and extruding it through a die to form pellets or granules.
There are different types of plastic recycling and granulating machines available, including single-screw and twin-screw extruders. Some machines also include additional features such as screens to remove impurities from the plastic waste or cooling systems to ensure the pellets are solidified properly.

Plastic recycling and granulating machines are commonly used in industries that generate large amounts of plastic waste, such as packaging, automotive, and construction. By recycling plastic waste, these machines help reduce the environmental impact of plastic disposal and conserve resources by reusing materials that would otherwise be discarded.
