SLJ series twin-screw extruder
This series of twin-screw extruders features a structure where both screws rotate in the same direction. The precise interlocking of the screw sleeves and mixing blocks mounted on the two screws ensures excellent dispersion and mixing of multi-component raw materials under hot conditions. It is a crucial guarantee for obtaining powder coatings.

Main component description:

Screw, cylinder
Adopting a "building block" structure, it has good interchangeability and can be used in any combination according to different material processing techniques; The cylinder body is made of nitride steel and bimetallic materials, which are wear-resistant, corrosion-resistant, and extend the service life; The threaded components are made of nitride steel and high-speed tool steel, and the curves are designed with computer-aided design, combined with unique processing technology, to ensure the normal tooth clearance of the threaded working section and good self-cleaning performance; The specially designed connection method and transmission device enhance the strength of threaded components and core shafts, achieving the goals of uniform material dispersion, good mixing and plasticizing effect, short material retention time, and high conveying efficiency.

Deceleration system:
Using a dedicated gearbox, the transmission components are made of high-quality alloy carburizing steel, combined with carburizing, quenching, and gear grinding processes. The key components have undergone surface strengthening treatment. This system has the characteristics of high speed, high torque, and low noise.


Feeding system:
Adopting a quantitative feeding system with a twin-screw mixer, the feeding is uniform and accurate, without the occurrence of material jamming.

Electronic control system: Imported electrical components are selected, the control panel is a human-machine interface, and various parts of the equipment are controlled in a "modular" manner (which can also be configured according to user requirements). The multifunctional module structure is clear, with safety interlock devices, which truly reflect the operation status of the equipment. The control is correct, the sensitivity is high, and the operation is convenient.
Technical features:
●The high-speed design of the screw achieves high output and mixing effect.
●The barrel has an efficient heat exchange and automatic temperature control system.
●The barrel is designed to be split, making cleaning convenient.
●The feeding system is equipped with measuring screws, ensuring the correct and balanced feeding amount
Has excellent self-cleaning ability.
● Easy cleaning and maintenance.
● Operational safety.
