Parallel double screws extruder

Parallel double screws extruder
Extruder System
The screw and barrel is of the building block system structure, and with good interchangeability, can be combined wantonly according to different materials processing; the barrel, made by nitrided steel and double-metal materials, is resistant to wear and corrosion and extended in service life; the screw element takes nitride steel and high-speed steel as raw materials, coupled with computer-aided design for curve and unique processing technology, the normal tooth surface interval in the thread active section is guaranteed with good self-cleaning; the specially-designed connection type and transmission enhances the strength of screw element and central spindle. In all, the system can achieve uniform dispersion of materials, good mixing and plasticizing effects, short material retention time, and transmission efficiency.
Deceleration System
The special reduction box for plastic machinery. The transmission parts are made by high quality high alloy carburizing steel through carburizing, hardening, and grinding, and key pieces, added with surface hardening treatment, with the tooth surface strength of HRC54-62, core hardness of HRC30-40, and 6-grade precision of gear. The system achieves high speed, high torque, and low noise.
Feeding System
The quantitative double-screw feeding system with mixer is employed, ensuring uniform and accurate feeding.
Electronic Control System
The system uses standard electrical components, human-computer interface, “module” control of various parts (also be configured according to user requirements), and multi-function module of clear structure, and safety interlocking device (such as lubrication under-voltage protection, nose pressure protection, overcurrent protection, etc.). It reflects accurately the equipment operating conditions, and has the features of control accuracy, high sensitivity, and easy operation.
Heating System
The cast aluminum, bronze, and ceramic resistance heating equipment is used with uniform heating, fast warming, and high temperature control accuracy.
Temperature Control System
The dual-channel temperature controller is responsive, easy for temperature setting and adjustment, and high in temperature control accuracy.
Cooling System
Water cooling, oil cooling, or air cooling is adopted to get rapid, uniform and effective cooling.
Vacuum System
The built-in vacuum system, with the vacuum degree up to 0.09Mpa, ensures adequate plasticizing of materials and improvement of product quality.
Auxiliary Machinery
In accordance with different processing needs, it can be in these pelletizing forms such as cold-drawn bar, towline pulling, air-cooled die hot cutting, and water ring hot cutting
