Pelletizing line design for soft raw material is different from the design for rigid raw material
SOLUTIONS FOR SOFT RAW MATERIAL AS BELOW
LDPE /LLDPE /HDPE FILM/PP FILM/PP WOVEN BAG
RIGID RAW MATERIAL AS BELOW
HDPE/ LDPE/ PP/ ABS/ PC/ PS/ PA/ PA66
The pelletizing line for soft raw material will be equipped with agglomerator normally, which is used for tear film into small pieces and then pinch it into a ball to rise efficiency of raw material feeding to barrel.
Bright spot(one line for 2 different kinds of raw material)
POLYTIME-M could provide the design for both soft and rigid raw material by one production line(Under certain conditions,for example customer could accept output capacity difference) 76%
- Technical Parameter -
Rigid Plastic Granulation Line
Soft Plastic Granulation Line
Single stage or Double stage?
Double stage granulation line is generally used for the raw material which after washing,it could bring 2 times degassing to get rid of moisture,also 2 times filtering to make pelletizing be more clean.
Single stage pelletizing line is used for clean raw material such as industry waste,including cutting edge of plastic package manufacturing.
- Features -
CONICAL TWIN-SCREW EXTRUDER
■ Servo motor, 15% reduction in energy consumption

Production Line Structure Type
Single stage- Suitable
for Lightly dirty raw materials
Double stage-Suitable
for severely dirty raw materials
Cutting Type
●Water-ring cutting (Suitable for HDPE, LDPE, PP)
Polytime-M hot die face pelletising systems have undergone another stage of development. The focus has always been on straightforward handling and easy maintenance.
■Maintenance-free and smooth mechanical action of knife head pressure
■Knife head driveshaft with direct drive
■Outstanding cutting precision in combination with fully automatic pneumatic cutting pressure setting
■Pelletiser knives and die face have a long service life
■Under-water cutting (PET recommended)
■Strips cutting (Suitable for various materials)
Screen exchanger
●Board double position hydraulic
Cheap cost, simple operation, but filtering area is not big
●Double column hydraulic screen changer
Cost is higher than board double screen exchanger, a lttle bit complicated operation,but much bigger filter area, it helps to decrease the frequency of replace filtering net.
● Automatic laser filter
For primary filtering, it is generally installed on the first stage of pelleitizng line to remove big contamination, but investment is high.
Optimised pellet water removal screen with self-cleaning effect and easy-change filter cartridge.
Pellet centrifuge for enhanced drying performance featuring Direct Drive technology
Plower and noise protection integrated in pellet Centrifuge housing - compact downstream components
Folding housing cover on pellet centrifuge for simple cleaning when changing colours and straight forward maintenance
New pellet water separation screen
