SJSZ65/132 Twin screw extruder pelletizing making machine line with knife cutting
Features Specifications for SJSZ65/132 Twin screw extruder
pelletizing making machine line:
The PVC twin-screw extruder granulator is a high-speed twin-screw
extruder with forced conveying, high-efficiency plasticizing and
mixing and shearing dispersion. The back pressure of the inorganic
head is refluxed to avoid high shear and overheating. The
lower-stage extruder is a large-diameter single-screw extruder
operating at low speed, with independent temperature control,
low-speed operating with low shear force, internal cooling of the
screw to avoid decomposition of plasticized materials, and
single-screw extrusion to ensure the establishment of pressure and
stable extrusion Out.
PVC twin-screw extrusion granulator application range: heat-sensitive polymer processing, large-capacity exhaust gas devolatilization treatment. Typical materials: PVC cable material, PVC transparent material, PVC tube material, low-smoke, low-halogen or low-smoke halogen-free cable material, various PE cross-linked materials and rubber dehydration post-processing operations.
Product performance of SJSZ65/132 Twin screw extruder pelletizing making machine line:
1. Feeding system single screw or twin screw feeding, stainless
steel hopper, Japanese imported frequency converter.
2. Drive system Z4Eurotherm speed governor, can also adopt AC
variable frequency speed regulating motor according to user
requirements. DC motor, equipped with the most advanced British
imports
3. Coupling: direct-coupled transmission helps to improve the
power transmission coefficient
4. Transmission system: hard-tooth surface gear transmission,
transmission and deceleration are integrated, imported SKF
bearings, imported oil seals, and gears are forced to lubricate.
5. Extrusion system: screw length-diameter ratio 28-56, maximum
screw speed 500rpm, screw element material is high-quality alloy
steel W6Mo5Cr4V2, surface hardness HRC58-60 after heat treatment,
barrel bushing material is α101, surface hardness HRC60-64, The
threaded element and the mandrel are connected by the most advanced
involute spline.
6. Temperature control system The cast copper and cast aluminum
heaters are distributed in different positions of the barrel
according to the needs, all stainless steel soft water cooling
system, imported solenoid valve.
7. Vacuum system: Set up exhaust and vacuum ports according to the
process, the vacuum degree can reach -0.04-0.08Mpa, all made of
stainless steel.
8. Rack system: profiled steel welded integral rack, easy for
users to install. Stainless steel housing.
