Plastic Granules Making 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.
How It Works :
In the entire process, A plastic material, normally in flakes form
is placed
into hopper of 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. 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 strands. Plastic 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. 65 mm to 125 mm screw size extruder models available.

AC motor & pelletizing motor.
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.
Hydraulic screen changer provided to filter
molten plastic in case it contains dust or particles.
Die attached with hydraulic screen changer
which converts molten plastic into plastic strands after filtration.
Comes along power pack.
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.
AC drives from reputed brands to maintain
motor speed at desired rpm.
Pressure transducer with buzzer system for
hydraulic screen changer to detect mesh pressure. (Helps to notify labor
to change screen as soon as possible)
Accumulator power pack for hydraulic screen
changer to boost hydraulic up/down speed.
Automatic hopper loader to load raw material
into hopper with help of blower. (substitutes labor need)
Air knife, to prevent water entering into
pelletizing unit and helps for moisture free pellets as an output.
Forced feeder, for hopper to feed low
density raw material easily to boost production rate.
Manual die head, instead of hydraulic screen
changer. (to reduce the cost of machine) (best option for clean material
recyclers)
Barrel vent, for engineering grade material
like ABS & HIPS for moisture free granules and quality output.
PLC based HMI control panel with touch
screen display
Vibro shifter, to separate rejections and
finished granules effortlessly.
