The effective twin screw extruders facilitate the use of complex processes and therefore are highly valued in the PVC compounding industries with increased production of sophisticated PVC compounds with excellent performance qualifications.

What Types of Twin Screw Extruders Are Available?

Co-Rotating Twin Screw Extruders Explained

In the polymer industry, co-rotating twin screw extruders are the most type of extrusion equipment. This equipment contains twin parallel and revolving screws which rotate in the same direction within the barrel. As a result of their co-rotating motion, the screws are capable of effectively compounding, mixing, and even melting different types of materials, including PVC.

Conical Twin Screw Extruders vs. Parallel Twin Screw Extruders

There are two types of co-rotating twin screw extruders which are co-rotating parallel twin screw extruders and co-rotating conical twin screw extruders. Co-rotating twin screw extruders of the conical type have a barrel that is tapered, with the result that shearing and mixing elements in the extrusion process are greatly increased. But along with cylindrical barrels, co-rotating parallel twin screw extruders tend to enhance throughput and better conveying capacity as well.

Series Twin Screw Extruders: Features and Benefits

Inside the co-rotating twin screw extruder, we can also find the co-rotating series twin screw extruders. The presence of more than one screw element, possessing certain variations in their pitch configurations, enables the extruders to mix, add, melt, and compound with a higher degree of efficiency. Twin screw extruders are a reliable device for shaping compounds of the defined counterparts with the demanded working features.

How Does a Twin Screw Extruder Work?

In many industries, notably polymer working, the twin screw extrusion technology is quite advanced processing technology. The barrel and two screws are intermeshed, and both transport the metal as well as mix and heat it up to melting point. Since the screws turn the same way, this results in strong shear and mixing actions that enhance both compounding and shaping of the material.

The Relationship between Screw Speed and the Shaft Assembly

The twin screw extruder efficiency, as well as the final product, is influenced greatly by the shaft and screw rotating speed. The operational screw speed will dictate how long the material stays inside the machine, which then determines how much mixing and processing takes place.

Depending on the shaft construction, which includes the screw flight depth, pitch, and design, temperatures during melting, mixing, and even transporting the material to be worked on will change significantly.

Control Systems in Twin Screw Extruder Machines

The design of Modern’s TWIN SCREW EXTRUDER includes parameters surveying and control. These control systems are important to us because they give data concerning temperature, torque, and pressure, which is vital for us to tune the process for good and consistent quality of the final product.

This is not the case as those systems can also allow the setting of the optimal speed of rotation of the screw and plenty of its other parameters, the temperature of the barrel as well as other conditions of processing different materials.

So, based on how the twin screw extruder works, what is the maximum ratio to which it is reasonable to increase the speed of the screws, and what is the significance of the control systems, they will be able to determine with what parameters and for what purposes twin screw extruder machines should be mounted and operated.

What Are the Benefits of Using a Twin Screw Extruder Machine?

The operational features that clearly stand out on a twin screw extruder include the high torque characteristics. This form of extruder is capable of processing many materials. So equipped, the machine has high mixing and compounding capabilities because it has dual intermeshing screws, and thus, all the additives, fillers, and polymers are sufficiently mixed.

Other than the above, twin screw extruders are said to be energy efficient. The design features of these machines, together with the control systems now available, make it possible to control the process parameters within very narrow ranges, which enhances the extrusion process while at the same time reducing the energy utilized. This lower energy use helps to reduce operational costs and enhances green manufacturing.
