PP film granulating line is mainly used for processing waste plastic film (industrial packaging film, agricultural film, greenhouse film, beer bag, handbag, etc.), woven bags, etc.
PP film granulating line is mainly used for processing waste plastic film (industrial packaging film, agricultural film, greenhouse film, beer bag, handbag, etc.), woven bags, etc. The PP film granulating machine is suitable for most common waste plastics, electromechanical separation, simple operation and convenient use.
The film granulating machine has to withstand various dynamic loads from the moment it is put into production. All parts are affected by work transmission wear, melting material and decomposition gas corrosion, environmental pollution and operating method errors.
After working for a period of time, the working performance and efficiency of the film granulator will change or decrease slightly. Maintain the plastic granulator to keep its working performance and production efficiency in a normal state for a long time to improve economic benefits.
During the normal production work of the plastic granulator, the operators of each production shift shall check the maintenance of the film granulator. Such as lubricating the equipment after taking over, tightening loose nuts, scrubbing the oil on the equipment, etc. These tasks are also part of the operating procedures of the film granulator. Therefore, the operators of the plastic granulator carefully implement the operating procedures. Operating in accordance with the requirements of the production operation sequence is one of the contents of better maintenance of the equipment.
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.
