Heavily printed PE film granulation line is used for agricultural film recycling, shrink film recycling, printing film recycling, packaging film recycling, composite film recycling etc.
Heavily printed PE film granulation line is used for agricultural film recycling, shrink film recycling, printing film recycling, packaging film recycling, composite film recycling, aluminized film recycling, and film scrap recycling. The advantages of heavily printed film granulation line are: high efficiency, high output, wide application, low labor intensity, and high quality particles.
The recycling and pelletizing of PE film is relatively simple, and single-stage or two-stage pelletizers can be selected. As the packaging contains heavier printing, Preh Machinery recommends the use of a two-stage film pelletizing production line.
The PE film granulation line adopts horizontal water ring granulation, which is easy to operate, simple to maintain, and has a high output. The double-stage exhaust effect and filtering effect are better than ordinary plastic granulators.
Purui Machinery has more than 20 years of professional design experience and more than 10 years of production and sales experience, surpassing its peers in terms of product appearance and product performance. At the same time, the company has a group of professional after-sales service, whether you are a domestic customer or a national customer, you can go to the user’s factory for maintenance services.

Belt Conveyor
As standard design, plastic scraps such as film, filament, raffias conveyed into the compacting room through belt conveyor; to handle rolls’ scraps, roll hauling off device is an optional feeding method. Motor drives of conveyor belt and hauling device cooperate with ABB inverter. Feeding speed of conveyor belt or roll hauling off is fully automatic based on how full the compactor’s room is. Metal detector can be combined with belt conveyor, and can interlock with contrl system, to warn and stop the system, in case that metal is found in feeding.
Compactor / Agglomerator
The rotatory blades of compactor will cut up incoming scraps. Frictional heating which caused by high speed rotatory blades will heat and let scraps shrinking just below their agglomerating point. Optimal designed guide structure compacts the material and directs it into extruder screw. Crushes, dries and compacts the material which enables a fast and stable feeding from the compactor directly into the extruder.
Extruder
A specialized single screw extruder applied to gently melt the pre-compacted material. The plastic scraps will be well melted, plasticized in a 36D processing section. With double-zone vacuum degassing system, volatiles such as low molecular and moisture will be removed efficiency, especially suitable to heavy printed film and material with water content.
Water-ring Die-face cutting system
Water-ring die-face/Strand cutting methods are usually adopted. In water-ring die-face cutting system, the rotary cutting blades will be pneumatically fit completely and closely to the die-face surface to ensure efficient cutting. Rotary speed of the blades is automatically adjusted by module system according to melt pressure at the die face.
Vibration drying system
Advanced dewatering vibration sieve combing with horizontal-type centrifugal dewatering present high performance dried pellets and lower energy consumption.Combine crushing, compacting and plletizing steps in one system, less-labor cost.Higher efficiency feeding, suitable to film, filament, raffia, foaming materials;Higher output and lower energy consumption
