PET Plastic Pelletizing Machine
1.This machine line is used for the PET plastic pelletizing ,the final product is PET pellets.
2.After this machine can get the PET pellets,which can used to produce new product.
3.Machine's capacity canbe 250-700kg/h.
4.This pelletizing machine will according to customer's material and require to design different specification.
5.Working Flow of PET pellet granule making machine PET plastic pelletizer granulator recycling PET plastic pelletizing machine:
Feeder → Efficient Extruder → Non-Stop Hydraulic Screen Filter Changer → Water Flow Cooling → Under Waster Cutting → Vibrating → Blower → Storage Hopper → Electric Control Panel
6.Features of PET pellet granule making machine PET plastic pelletizer granulator recycling PET plastic pelletizing machine:
The screw is made of high tool steel 38 CrMoALA or W6Mo5Cr4V2. Special screw combination Euro-style rectangle barrel, reflux refrigeration channel optimized and disposed, which makes temperature difference in D areas smaller.
Co-rotating Twin Screw Extruder with High Torque Gearbox. Due to high torque gearbox, The specific torque of gearbox is 10.3 N.m/cm3, So we can process PET in lower temp & lower speed, but high output.
Innovated design of heater-tightened style insures high efficiency of heat transfer and high longevity of heater.
The material is used high quality nitride steel, corrosion proof or antifriction with corresponding processed special designed two sets of vacuum. The vacuum system is used for removing moisture & volatile matter from PET. It is assembled with vacuum pumps collecting tank. With PLC and HMI control for interlock, you will get the vacuum level less than 0.3Kpa. It is very close to the ultimate vacuum. You will get PET with IV drop less than 5%, it is about 0.05dl/g.
The selected material of drive components is dainty, including super intention alloy, cementiteing steel, cementiting and grinding.
New Under Water Strand Pelletizing Machine system: The strand go into the pelletizer by the water flow, even the strand is break during changing the filter, there will no waste after starting.
We can control the temperature of the final pellets. We can make it hot, if you want to crystallize the final pellet. It will save the energy to heat up pellets.
7.Function of the PET pellet granule making machine PET plastic pelletizer granulator recycling PET plastic pelletizing machine:
一. Screw feeder: the first step of the pelletizing recycling machine, PET plastic flakes/scraps conveyed into the hopper through
screw, the screw connect sensor to detect the material in hopper, once the flakes are full in hopper, the screw will stop; and
once empty, the screw feeder will begin working.
二. Extruder: to plasticization and degassing, a specialized single screw extruder applied to melt the pre-compacted material. The
plastic scraps will well melted, plasticized in the first stage extruder, and the plastic will be extrude by the second stage
extruder. 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 some water content.
三. Non-stop hydraulic screen filter changer: double stage filtering, fore filtering in the first extruder, and fine filtering in
the second extruder, to reduce the frequency of filtering sieves changing. The requirements on the filter technology depend heavily on the quality of the input material as well as the planned use of granules.
四. Water flow cooling: made of 304 stainless steel, 3 meters length that with flowing water, too cooling the melted PET strand.
五. Cutting pelletizing: Water proof design, that can cutting the PET strand in water directly, this can save more waste. Supplied with speed steel and hard alloy steel cutting blades for reliable performance. Compact structure allows less maintenance.
