GENERAL
DESCRIPTION
The LLDPE raw material with suitable masterbatch
is being fed in to the barrel cylinder through
storage hopper. The barrel is preheated
by heating zones and suitable temperature
control system to process the input material.
The rotating screw pushes the material towards
die end with uniform and homogenized plastics
melt. The screw is rotated by suitable AC
motor coupled with heavy duty gearbox.The
plastics strands extruded from die are fed
in to high speed Pelletiser unit after they
get cooled and traveled through SS water
cooling tank. Pelletiser cuts the strands
in to desired size of pellets which can
be collected in to storage silo.
EXTRUDER
Extruder unit is consisting of heavy &
sturdy frame fabricated from MS plates and
channels. The screw and barrel are made
from high tensile alloy steel which are
duly nitrided, finished polished and hardened.
The screw and barrel are specially designed
to process the PE material. Main screw is
rotated by suitable AC motor & via rubber
belts coupled with pulleys and a heavy duty
gear box The barrel has been devided in
to heating zones for accurate temperature
control. Thermocouples are provided for
each heating zones for temperature control
through digital temperature controllers.
Heavy duty thrust housing is used to withstand
high back pressure during the process.
DIE HEAD
Compact Die head is fitted with flange,
beaker plate and one special die to extrude
pellets. Swivelling arrangement for die
is provided for ease of cleaning.
COOLING TANK
Water cooling tank is fabricated from stainless
steel plate which is mounted on adjustable
stand for height adjustment. Guide rollers
are provided to convey the strands forward
towards pelletising unit.
PELLETISER
UNIT
Specially designed Pelletising unit is made
from heavy MS channels structure. Which
is consisting of sets of moving blades and
stationery blades which are mounted on balanced
rotor. The unit is driven by suitable AC
motor and AC variable frequency drive for
speed control so as to produce desired cut
length of pellets.
ELECTRICAL
CABINET
The Electrical panel is fabricated from
powder coated MS sheet with dust proof construction.
Main Ammeter, Input voltage voltmeter, Emergency
stop, Starter for main Extruder motor, Digital
temperature controllers for barrel and die
heating zones, with individual ammeters
for each zones, AC variable drive for pelletiser
motor are provided. Detailed Electrical
circuit diagram with rating of all switch
gears and with terminal connectors diagram
is provided with panel
Salient Features:
• Screw & barrel are made of
nitro alloy steel, nitrided, finished polished
and duly hardened for longer life.
