Screw element and extruder barrel

Features
The screws are entirely modular according to the needs and the work type; The geometric configuration of the screw is featured with self-cleaning elements mounted on splined shafts even HT (high torque).
The modular elements used for the geometric composition of the screw, either used for transport, kneading blocks, mixing or special, are bilobed or trilobed mounted along with the bilobes and can be realized with high OD/ID ratio.

Description:
The flexible modular principle is realized with screw barrel sections from the wide
Range ofdifferent designs possible. Fast, intensive and uniform heating ofthe screw
Barrel section is ensured by electrical heaters. The barrel sections are cooled with
Water, by means ofan internal bore system, with bores arranged close to the inside
Barrel wall.

Barrel sections are available as:
Closed barrel section
Barrel section with opening for material feed or for devolatilization
The processing section is provided with stainless steel plates as a protection against
Accidental contact.
Screw Elements: High-speed steel W6Mo5Cr4V2, nitrogen treatment.
Screw Shaft: High performance alloy steels, 40CrNiMoA; With standing high load, Etc
Description
The inter meshing screws co-rotate and wipe each other with narrow clearance so that
No residues are left in the screw flight and clean effort is thus reduce.
Screw elements with various pitches and lengths
Kneading blocks with various angles ofstagger, numbers ofkneading disks and disk
Widths.

Features:
1. Screw components designed by computer aids is kneading type, has excellent self-cleaning function, the new kneading block design effectively avoid the problems of overheating and energy consumption.
2. According to process system and formula requirements, the unit can optimize its L/D ratio, barrel structure, screw array, venting number and location, feeding method, electrical control methods etc. For rational allocation.

Our machine types:
1. Co-Rotating Parallel Twin Screw Pelletizing Extruders
2. Single Screw Pelletizing Extruders
3. Die Face Cut (Air Cooling) Pelletizing Extruders
4. Double Stage / Double Degassing Recycling Extruders
5. Crushers, Mixers, Storage Tanks, Vibrators, Granulators, Blowers
6. Extruder spare parts
We are manufacturer of twin screw extruder, also can supply all the spare parts.
Like screw, barrel, feeder, die head electric controller and gearbox.
