Difference Between Parallel And Single Extruder

Plastic single-screw extruder, as a type of extruder equipment commonly used in the plastics processing industry. 

It has a simple design and structure and a lower price, it is widely used, such as a single screw extruder SE series. But it has limitations and advantages in use.

Plastic extruder and parallel twin-screw extruder is different. Both are driven by a motor. Strength varies due to the number of bolts.

They are used in areas and situations to meet different needs. Now let’s do some studies on the comparison of the two types of machines.

In a single theory advanced than the parallel type of twin extruder; for balanced by the radial force, but parallel types of twin-rotor balancing radial force through SKF bearings. 

SE plastic extruder screw compresses the air with one single and two-wheel star, and three of them in direct contact with each other, thus leading to serious fiction between star wheel and rotor. 

There will be a great inner leak in a large head, and the amount of displacement is reduced. 

While the parallel-twin screw extruder having energy-efficient motors with a speed of1460 r / min. The higher the speed, the greater the wear is. So a single screw motor tearing and serious wear, increased operating costs.
