Mother Baby Plastic Recycling Machine (for Recycling and
Pelletizing) :
Plastics granules making machine which works on a principal of plastic extrusion
process, is a normally high volume manufacturing process where a polymer
material, enriched with the desired additives, is melted and formed in a
continuous process. Where output can get form of granules, tubes, sheets, lumps
and etc. Double stage plastic recycling machine helps for better quality with
high performance while maintaining the ratio of extruders. Helps to remove
complete moisture and twice filtration.
How It Works :
In the entire process, A plastic material, normally in flakes form
is placed
into hopper of mother extruder, usually made from fabricated from
mild steel or
fabricated from stainless steel as per material requirement. There
is a hopper
magnet fitted inside the hopper to stop metallic particles from
entering inside
the barrel. The raw material in the form of flakes, is gravity fed
into the
hopper and through the feed throat, drop on the rotating screw.
Barrel has
several amount of heaters fitted on the outer diameter. Which heats
up the
barrel to get extrusion process job done. Screw is connected with
helical
gearbox and AC motor which helps to rotate the screw of mother and
baby
extruders. Raw material in flakes form starts to move forward along
the rotating
screw and enters the heating spot of barrel. Where it starts to
melt. Molten
plastic reaches the end of the barrel where hydraulic screen changer
is fitted
which filters the molten plastic and converts it into plastic lumps
out of
unique design die which helps to remove all possible moisture
contained in
lumps. Plastic lumps then drops into baby extruders hopper. Baby
extruder also
does extrusion process and molten plastic moves forward, reach to
the second
screen changer. Where screen changer filters the plastic and
converts it into
plastic strands. Strands moves forward and drops inside the
stainless steel
water tank and its temperature starts to cool down. Plastic strands
then enters
the pelletizer machine which turn it into pellets.
Model Range :
various models available which are classified according their production
rate. 90 mm to 130 mm screw size extruder models available.
Production range :
Production Range of 100 kg/hr to 500 kg/hr.
Salient Features:
Screw & barrel of mother and baby extruders
are made of EN41-B mild steel, nitride and honing finished for quality
production & longer durable life.
Optional : Tungsten carbide coated screw &
barrel available, for high production machines to provide a longer
durable life.
Screw design for reprocessing & coloring
application of LLDPE, HDPE, LDPE, PP, HM, ABS & HIPS etc.
Screws are designed for specific material to
get better quality for specific material while producing single category
material or universal design for every material.
Barrel has been divided into heating zones
for accurate temperature control.
Digital pyrocontrol panel for faster heating
& energy saving.
Thermocouples are provided for each heating
zones for temperature control through digital temperature controllers.
Movable motor attachment provided for both
extruders main AC motor & pelletizing motor.
Both Extruder unit is consisting of heavy &
sturdy MS channel’s fabricated frame and covered with CRC sheet.
High efficient hopper magnet provided for
detect and restrict the ferrous material from the polymer.
Screw is rotated by suitable AC motor with
heavy duty helical gear box. AC motor and helical gear box are from
reputed brands for both extruders.
For both extruders, Hydraulic screen changer
provided to filter molten plastic in case it contains dust or particles.
Unique designed die attached with hydraulic
screen changer of mother extruder which converts molten plastic into
plastic lumps which removes all possible moisture and second extruders
screen changer turns it into plastic strands after filtration. Comes
along single power pack for both screen changers.
Cooling tank is fabricated from stainless
steel sheet, which mounted on height adjustable fabricated stand. Where
guide rollers are provided to convey the strands forward towards
pelletizing unit.
Pelletizing unit fabricated from heavy
angles, where peletizer is mounted which has consisting sets of carbide
tips moving blades. Unit is driven by AC motor.
Extras (Optional) :
Tungsten carbide coated screw
&
barrel, for high RPM machines to boost screw life.

into
pelletizing unit and helps for moisture free pellets as an
output.
Forced feeder (for mother extruder),
for
hopper to feed low density raw material easily to boost
production rate.
Barrel vent, for engineering grade
material
like ABS & HIPS for moisture free granules and quality output.
