When we use a twin-screw extruder, if we want to give full play to its performance, we must first understand its characteristics before using it, so what are its characteristics? TENGDA Plastic Extruder Machine Manufacturers introduced its structure, standard accessories, and its size in the article. In addition, in the process of operating the machine, we must pay attention to some factors that may affect our use. Hurry up and listen to the introduction of TENGDA Plastic Extruder Machine Manufacturers in the article!







What are the characteristics of a twin-screw extruder?

1. The twin-screw extruder has a barrel with an extension range of 4 and 6D, which can realize precise process design and meet the specific requirements of customers. All barrels can achieve precise temperature control. Cooling is achieved by cooling water jets, and high-performance electric heating rods enable direct and rapid heating. The C-shaped clamping flange system facilitates the assembly and disassembly of the cylinder, greatly reducing the installation time for cylinder replacement.



2. The standard equipment of the twin-screw extruder includes a solid base frame, which is specially designed to accommodate the temperature control unit and the oil lubrication system. The equipment uses advanced control software, which can be seamlessly integrated into the digital factory, ready for Industry 4.0, and greatly improves the ease of use.



3. The screw diameter of the twin-screw extruder has three sizes, 52, 62 and 77 mm, which can be applied to various applications and output ranges, and the screw speed is 700 rpm or 900 rpm. The product quality is stable, the operation is simple and the reliability is high. Its high productivity ensures companies a secure investment with a significantly shorter payback period.







Factors affecting the performance of twin-screw extruders:

1. Due to the increasingly high requirements for plastic properties in downstream applications, it is required to have various properties such as high temperature resistance, hydrolysis resistance, and scratch resistance, which forces upstream extrusion manufacturers to have some higher requirements in terms of technology to meet customer needs.



2. As the application side has higher and higher requirements for innovative materials, blending and modification companies also have new requirements for blending equipment and processes. Three main indicators of twin-screw extruder equipment performance: specific torque, volume ratio, and screw speed.



3. Specific torque refers to the torque force of the screw to the material per cubic centimeter. Under higher specific torque, the material has a higher filling degree in the screw, and the average shear force will decrease.



4. All in all, through the preparation of ultra-high torque and high groove depth ratio to increase the production capacity of a single machine, increase the equipment groove depth ratio and torque to obtain more process flexibility space, and use the high groove depth ratio to reduce specific energy consumption while increasing output rate, it will be possible Get double economic benefits.
