PP Big Bag Recycling Machine
PP big bag recycling line can treat with pp ton bag etc.
The whole process include shredding, water rinsing, friction washing, drying by washing system; compacting, plasticization, pelletizing and drying by pelletizing system. PLC intelligent system realized high automatic, the whole line just need 3-4 man to operate.
With 25 years of experience in recycling, KITECH not only mastered the key technology, but also improved machine designs to address specific product features. KITECH offers pp big bag recycling solutions that are high output and low energy consumption.

PELLETIZING PROCESS
Feeding
Belt conveyor for plastic scrap feedingl automatically, Feeding speed adjustable by inverter controller according to the feeding amount.
Compating
The plastic material got cutting, mixing and preheating in compactor uniformly, to ensure the material heated and dried effectively.
Extrusion
High efficiency barrel and screw used for extruder with excellent plasticizing result and high output capacity. Adopt high wear resistant alloy material to ensure 1.5 times service life of normal one.
Degassing
Force double vacuum degassing system to get rid of the low molecular, moisture and printing ink effectively, make sure high quality output pellets.
Filtration
Plate type, piston type, back flush type and automatic self-cleaning type filter, you have different choice according to impurity contents in material and your habit.
Pelletizing
New European design water ring pelletizer, Cutting speed of pelletizer controlled automatically by PLC according to the pressure of die head, which could achieve the uniform size for output pellets.
Drying
Vibration dryer combined with horizontal type centrifugal dryer to get well dried final granules.
Controlling
Thanks to Siemens PLC and HMI, KCP series recycling pelletizing machine provides high intelligent operation system which is easy to operate and save manpower.
