300/600 Plastic mixing machine high speed PVC heating cooling mixer
Application:
The SRL-Z series high-speed mixing unit is mainly used for the
mixing, mixing, coloring and drying of various resins such as
polyethylene, polypropylene and polyvinyl chloride, as well as
drying and devolatilization before the processing of engineering
plastics such as ABS and polycarbonate. Such processes can also be
used for the mixing of phenolic resins. The unit combines the hot
mixing and cold mixing processes, and the hot mixed material
automatically enters the cold mixing to cool it quickly,
eliminating residual gas and preventing agglomeration.
The SRL-Z series high-speed mixing unit has the characteristics of
high degree of automation, good mixing effect, full function,
compact structure and beautiful appearance. It is an ideal
equipment for the production of pipe and profile. The main shaft
adopts a new type of sealing device, and the hot mixing has
self-friction and electric heating and steam heating functions. The
lid is double-sealed, and the cold-mixing adopts an arched lid,
which is not easily deformed. The unit is equipped with a pulse
dust collection device. The hot mixing lid is opened pneumatically,
and the cold mixing lid is opened using a hydraulic or pneumatic
system. The blades are specially treated by static and dynamic
balance testing machines.
Plastic mixer features:
A1: The main shaft seal adopts PTFE seal sleeve, skeleton oil seal
and air pressure three-way seal to ensure no leakage.
A2. A plane bearing specially designed to withstand the axial force
is added to the rotating structure of the main shaft, thereby
avoiding the premature damage of the upper end bearing
simultaneously bearing the radial force and the axial force,
thereby greatly prolonging the service life of the machine.
A3. The bearing is installed with a special heating installation
tool to ensure that the inner and outer rings of the bearing move
at the same time. The conventional method of hammering the outer
ring or the inner ring of the bearing is avoided, so that the ball
is stressed during the assembly process and the bearing life is
severely shortened.
A4. The design of the discharge part structure is designed
according to the characteristics of the solid material. The
installation of the discharge air blowing device overcomes the
shortcomings of the traditional liquid design and avoids the
defects of easy leakage.
A5. Both the paddle and the pulley pass the balance test, so that
the machine runs without vibration.
A6. Hot mixing has a heating function of self-friction and electric
heating.
A7. The lid is double-sealed and not leaking. The shear-sensitive
crystalline powder is mixed in batches and the liquid is mixed into
the solid.
A8. The discharge valve is plugged with a plunger type. The inner
surface of the door block is closely matched with the inner wall of
the container, and there is no dead zone of the mixture, so that
the materials are evenly mixed.
A9: The cold machine blades use large angled blades to force the
material to rise along the inner wall of the container and return
to the cooling jacket for cooling purposes.
A10: Optional variable frequency speed regulation to protect the
motor and power supply line, while saving 20-25%.

The high-speed mixer must have a dedicated person responsible for
the start-up operation and operate in strict accordance with the
operating procedures.
(1) Inspection items before operation
1. Check the connection parts of the equipment in detail and
tighten them without loosening.
2. Whether the moving parts are flexible, whether the stirrer is
installed firmly, and whether the spindle rotates lightly.
3. The V-belt should be evenly tightened, and the bolts on the
motor seat plate are tightened without looseness.
4. The inner cavity of the mixing container and the discharge body
should be cleaned and free of dirt.
5. Check if the direction of rotation of the motor is consistent
with the direction indicated by the mark.
(2) Precautions when the equipment is running
1. The motor should be stable when running, no abnormal sound, and
check whether the temperature rise is normal.
2. Whether the rotating parts such as spindle bearings and V-belt
pulleys are running normally. If there is abnormal noise or
vibration, stop immediately and check. If there are damaged parts,
they should be replaced and repaired immediately.
3. When changing the color of the material machine, the mixing
container and the discharge part must be cleaned.
4. Equipment feeding shall not exceed the maximum loading factor.
When the equipment is running, if adding plasticizer should be
slowly added, the plasticizer should not be suddenly poured into
the machine body, causing local material to agglomerate, causing
the load to suddenly increase and damage the equipment.
V. Maintenance and maintenance
When using high-speed mixers, maintenance procedures should be
established. In addition to general equipment maintenance rules,
the following items must be noted:
1. After the equipment has been in operation for 10 hours, it
should be inspected thoroughly. If necessary, the joints must be
tightened once.
2. After the equipment is operated for 10 hours, check the tension
of the V-belt. When tightening the V-belt evenly after adjusting
the tightening screw, tighten the locking bolts of the motor base
plate to prevent loosening.
3. All parts of the equipment must be kept clean, especially the
inner wall of the mixing container and the refueling hole in the
discharge hole should be cleaned. If the equipment is not used for
a long time, the inner wall and the discharge part should be coated
with anti-rust grease.
4. Equipment should be inspected frequently, regularly inspected,
and damaged parts should be repaired and replaced in time.
5. Electrical equipment should be inspected regularly, especially
the heater, and the damage should be replaced in time.
