Small twin-screw extruders have a wide range of functions, such as excellent transport capacity, exhaust devolatilization ability, and excellent mixing and dispersing ability. They are widely used in modified granulation of multi-component polymers, or in direct extrusion of multi-component blends of polymers. So what are the small twin screw extruders made of?
(1) The screw and barrel of small twin-screw extruder adopt advanced building block design, and the screw is composed of various interchangeable thread elements. Therefore, according to different materials, different process requirements can be flexibly combined into an ideal screw configuration, to achieve a multi-purpose machine, a multi-purpose purpose machine, and the worn threaded components and barrels can be replaced locally to reduce maintenance costs.
(2) The tooth profile of the screw element of the small twin-screw extruder is optimized by computer, which has good self-cleaning ability and optimal volume power.
(3) Small twin-screw extruder can be combined with one-stage, two-stage or multi-stage vacuum exhaust structure, which has strong exhaust devolatilization ability and can complete various mixing operations with high devolatilization.
(4) The screw element is made of high quality alloy tool steel, and the working surface is hardened to meet the requirements of various blending operations. Nitrided steel barrel can be used for general operation requirements of the user barrel, for wear or corrosive operation requirements of the user barrel can be used bimetal high wear-resistant, corrosion-resistant barrel.
(5) The gearbox of deceleration distribution adopts the structure that integrates deceleration and torque distribution, which is compact and reasonable. The main parameters are optimized and determined, and the reliability is strong. The drive motor is stepless speed regulation by frequency converter. The driving motor and the transmission box are connected by the elastic pin coupling to realize the direct flexible transmission, which can ensure the smooth and safe operation of the equipment.
(6) The main engine is equipped with a feeding system, the feeding quantity can be adjusted smoothly and continuously, and the production capacity of the unit can be adjusted conveniently within a certain range.
(7) according to user requirements, multiple feeding systems can also be configured to meet different production process requirements.
(8) The temperature control system of small twin-screw extruder is heated by cast aluminium or copper heater, which has the advantages of fast heating up and long service life. The cooling system is cooled by high-temperature heat conducting oil without temperature shock and circulating cooling.
(9) The control system of small twin-screw extruder adopts the programmable computer controller system originally made in Europe, and the control temperature adopts PID and fuzzy control algorithm, so the control temperature is accurate. The driving motors of the whole machine can be controlled locally or online, and the operation is convenient, simple and easy to understand, and the interface is beautiful. All operation parameters can be set, modified or displayed by 7 inch true color touch screen, and has a variety of interlocking protection and alarm functions.
