For a right-handed screw, the rotation should be counterclockwise; for a left-handed screw
Another is the Igel element, a right- and left-handed screw
on the same shaft, which creates an accordion-type back-and-forth mixing effect.
It is made with a left-handed screw
element for the melting and a second one close to the die exit, preceded by a block of five kneading discs staggered at 45[degrees].
Profile 1 included a left-handed screw
element for melting and three blocks of kneading discs with positive (+30[degrees]), neutral (90[degrees]), and negative (-45[degrees]) staggering angles.
elements or blocks of kneading discs.
Another one is full-flight left-handed screw
elements and is often used for creating a material hold-up.
The degree of grafting mainly increases through kneading disc block and left-handed screw
element regions compared to right-handed screw elements.
It is composed of right-handed screw elements, two left-handed screw
elements and three blocks of kneading discs, with positive (+30[degrees]) and negative (-30[degrees]) staggering angles.
Screw-Barrel System '2' contains Screw Configuration '2,' which has two kneading disc block sections with a left-handed screw
element and a left-handed kneading disc block element with two input ports.
It has a melting section made of 15 kneading discs, and a mixing section made of 25 kneading discs followed by a left-handed screw
System '3' contains Screw Configuration '2' where has two kneading disc block sections with a left-handed screw
element and a left-handed kneading disc block element.
where the second section is considered to be a kneading disc block or left-handed screw
with poor pumping characteristics and [f.
