PA Film Granulation machine
Nylon film is known for its toughness, transparency, gloss, and
high tensile strength. It exhibits excellent heat and cold
resistance, as well as strong oil and organic solvent resistance.
Due to its superior abrasion and puncture resistance, combined with
a relatively soft texture and outstanding oxygen barrier
properties, PA6 films are extensively used in packaging various
products, including greasy foods, meat, fried items, vacuum-sealed
products, and steamed foods.
However, the production of nylon films generates a significant
amount of scrap material, which holds considerable recycling
potential. As a result, there is a growing demand for specialized
recycling equipment to process this valuable waste.
According to this characteristics type of PA film, the high
mechanical strength of the PA film, from the processing flow, it is
necessary to pre-shrink its size with s shredder before
granulation. After shredding, the final size about 60-80mm. Then we
design ML serious Compact Recycling Granulator. This type of
recycling machine has advanced cutting, compaction, and drying
combined with a gentle plasticization process design, which can
effectively maintain the performance of the material and improve
the quality of the recycled particles.
The PA film shredding by shredder, the shredded film feeding into
compactor by belt. Design the compactor we adopt the motor drives
the movable knife at the bottom of the compacting chamber to
rotate. The rotating movable knife and the fixed knife installed on
the wall of the compaction chamber form a cutting force and
generate frictional heat. The frictional heat causes the film to
shrink. The deflector on the wall of the compaction chamber
compacts the material downward, and the centrifugal force generated
by the rotation of the cutter head sends the shrink film into the
extruder screw.
it is equipped with an exhaust hole on the top of the compaction
silo, which is connected with the dust removal exhaust device
The film in the compaction chamber is being cut and compacted. And
the generated moisture and dust will be collected and stored by
this device.
Special design for single screw
The screw length to diameter ratio L/D is 36~32 normally
The long screw provides more space for process design, enabling it
to have functions such as melting, mixing, exhaust, and internal
pressure.
The screw material adopts bimetal processing technology to ensure
the wear resistance, corrosion resistance and service life of the
screw
After the film is processed in the screw process section, it will
be transported to the filtration system, second extruder,
filtration system and cutting system.
