KRSJ-series high efficiency single screw extruder
It’s design as twin-rank
entity, highlighting plasticizing function, it
makes sure the high efficiency and high performance extrusion.
Special barrier, BM type comprehensive mixing design, which
guarantees the mixing quality of material. High cutting and low
melting temperature ensure the extrusion at low temperature and
high properties.
Design philosophy and features:
1?High speed, high output, high quality
2?
Low plasticizing temperature
design, which ensures good-quality product extrusion.
3?High torque output, super
large thrust bearing
4??
High rigidity alloy steel gear and
shaft, Nitriding treatment,
gear grinding treatment, splash lubrication and forced lubrication
system built in hard-face tooth surface gearbox; Separate
circulation cooling system is connected.
5?High hardness, smooth
finish, ultra-low noise
6?Automatic hopper drying
machine eliminates the moisture of the material.
7??
Automatic feeder helps labor
saving.
8Automatic weighing feeder can be equipped with controller the
product weight per meter.
9?PLC/PCC smart control
system realizes the linkage between the master and slave machinery,
HMI monitoring, real-time monitoring for the production process,
and according to the actual situation, the control style is
changeable (temperature control instrument).
*0?
Screw & barrel is made of *8CrMoALA, and it’s been
azotized,
therefore, it’s wear resistant.
*1?High preciseness of
temperature control, combined cooling of air and water cooling,
special design of material entry, equipped with perfect water
cooling device and professional symmetric trapezoid slot
lining.
*2?products: PP-R tube, PE water and fuel gas supply
pipe, PERT heat-resistant underground heating pipe, PA*1/PA*2 oil
pipe and brake pipe for autos, PEX cross-link pipe,
AL-PEX/PPR/PERT-AL aluminum and plastics composite pipe, ABS pipe,
POM pipe, PVC/C-PVC pipe, UHMW-PE ultra-high molecular weight
polyethylene pipe, HDPE pipe and miniature concentration-bundle
optical fiber pipe and all kinds of co-extrusion composite pipes;
And it’s also applicable to some plate and sheet extrusion: PP, PS,
HIPS, PE,ABS, EVA, PMMA, PC, PET, PVB, PVC, etc; additionally, it’s
used to extrude wire, rod and other plastic material for project
use. If adjusting the extruder speed and change
screw structure, all kinds of plastic profile can be produced,
such as PVC, polyolefine products. Transform pelletizer
suitable for co-mixing, rectifyandpelletizing of all kinds of plastics. New
type grooved slot spiral feeding barrel makes sure the high-speed
production and high output rate.
KRSJ*5/*5 co-extruder and main machine can be connected, and the
co-extruder is equipped with rolling wheels for the convenience of
moving, in addition, its height and angle are adjustable, which
facilitates the connection between co-extruder and mould;
co-extruder is controllable either separately or synchronized with
master & slave machines, and it can also joints the
concentration control of PLC/PCC. This co-extruder is mainly used
to produce color stripe pipe, multiple-layer pipe, composite
profile and other products with special demands. Special extruder
can be ordered according to the customers’ requirements, L/D scope:
*3?1??*7?1. In addition,
non-standard extruder for special material can also be ordered.
(for example: bimetallic screw &barrel).
For those customers who require screw
& barrel and gearbox critically, the European imported products
would be a good choice.
