Product Description:
· The kneading elements are generally divided into three types: 30 °, 45 °, and 60 °. Among them, the conveying capacity of the kneading block with a staggered angle of 30 ° is the largest, and the pass ability of the material is the best (composed of seven pieces), but the mixing ability is normal, and it is often used in the first kneading area after feeding.
· The mixing effect of the kneading block at 60 ° is the best (composed of four pieces);
· The 45 ° kneading block is normal (composed of five pieces). In the screw configuration, it is used the most, and it is often used in series (2-4 pieces), and the effect is always good (depending on the type of resin base material and the type of modification operation).;
