APPLICATION
This
cone twin-screw roller
head extruder integrates
functions of a twin-screw
extruder with a
two-roll calender,
and is intended for
installation under
an internal mixer.
It can form the material
discharged from the
internal mixer into
contimuous rubber
sheet that
is supplied to a rubber
sheet-cooling machine.

STRUCTURE
FEATURE
1. The screws
are made of cast alloy steel
and chrome plated on the
thread
zone.
Each screw is directly connected
to a gear reducer, and two
gear
reducers'
input shafts are connected
each other by a universal
coupling,
and two screws are driven
by a DC motor reversely.
Counter-rotating
screws exclude need of mechanical
pushers.
2. The extrusion barrel
is made of case steel and
chrome plated on the
inner
surface. Hopper section
is equipped with sensors
for measuring of
compounds
level.
3. The extrusion barrel
is double-walled disign
and the screw is hollowed
for water-cooling.
4. Calender rolls are made
of chilled cast iron. Each
end of the roll is
connected
with one of two output shafts
of a gear speed-reducer
through
a universal joint separately
and is driven by a DC motor.
5. Temperature control device
controls temperatures of
screws, extrusion
chambers
and calender rolls.
6. Roll clearance can be
continuously adjusted by
adjusting devices
according
to requirements of production.
7. The machine is controlled
by the PLC. The PLC provides
continuously
adjustable
speed of the machine according
to the type and quantity
of
compounds.
