The HDPE LDPE LLDPE film pelletizing machine produced by Purui Machinery is a new model designed based on the compact granulation process, which specializes in the recycling and granulation of various types of films, woven bags, and other soft materials.
The HDPE LDPE LLDPE film pelletizing machine produced by Purui Machinery is a new model designed based on the compact granulation process, which specializes in the recycling and granulation of various types of films, woven bags, and other soft materials. Solve the problems of soft throwing and feeding difficulties, low output, low safety, low automation, high manual consumption, and substandard environmental emissions in the traditional granulation process. The maximum capacity of the film pelletizing machine can reach 1500kg/h.
The film pelletizing line adopts the method of compaction and crushing. After the material enters the compactor, it is cut and crushed by the cutter head at the bottom, and is driven by the high-speed cutting of the cutter head to generate heat by friction, which makes the material shrink by heat to increase the density of the material and increase the feeding volume. This process method has a great help to increase the production capacity of the film pelletizing line.
Normal:
Model | SJ45 | SJ65 | SJ90 | SJ100 | SJ120 |
Output(kg/h) | 10-60 | 100-150 | 180-250 | 250-350 | 300-600 |
High output,low consumption:
Model | SJ150 | SJ160 | SJ180 | SJ200 |
Output(kg/h) | 400-700 | 600-1000 | 1500-2000 | 2000-3000 |
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
