Plastic film granulation production line is working to process all kinds of LDPE/HDPE film, such as leftover material, useless shopping bag film, logistic packaging film, etc.
Plastic film granulation production line is working to process all kinds of LDPE/HDPE film, such as leftover material, useless shopping bag film, logistic packaging film, etc.
Usually the plastic film is collected in bale or loosen shape, needs an operator to feeding the film into compactor unit. A metal detector device is optional here for checking the metals inside of film, will detecting and alarming while finding the metals and stop the belt immedietely.
Plastic film after cut and agglomeration will be feeded into screw extruder in a short time.The electric heated screw in a special designed structure will melting the film. A powerful degassing station must be included here if the foil material is printed.
In the end of screw,we put a sensor the feel the pressure in the screen changing net.If the current here is overload,it will keep alarming and warn the operator to change the nets.
Plastic film granulation line adopts horizontal water ring cutting system is more easy operate.Cold water will cooling the hot granules immedietely. A inclined stainless steel flume will bring the cooled granules into dryer.
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.
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
