Product Description
                            Wear resistance Screw Element for Extrusion Machine

Technical parameter

The screw elements and kneading blocks are designed accurately, by precise processed, agile combination, with interchangeability, which can fulfill efficient self-cleaning, transmission, compounding, press-forming and etc. The screw is made of high speed steel W6Mo5Cr4V2 or 38CrMoAlA by special heat-treatment, which is possessed with high corrosion-resistant and high wear-resistant functions.
Groove depth3.856.

Different types of screw elements can be used in a twin screw extruder. Generally there are 4 major types of screw elements, kneading elements, backward-pumping elements and mixing elements. For each type there are many different types.

Conveying elements
The geometry of the conveying elements enables a good transport of the product through the extruder. Each conveying element is characterized by its number of flights, its length in millimeters, and its pitch. The pitch is defined as the axial length in millimeters, required for a complete thread. Conveying elements with a large pitch have a greater conveying effect than those with a small pitch. These elements are used to forward the material e.g. at feed openings, In order to avoid that pressure increase excessively at the openings.

Kneading elements
Kneading elements are mostly used for dispersive mixing, but they are also used for distributive mixing processes. They consist of kneading discs with a certain thickness. Like the conveying elements they are several parameters by which the kneading elements are characterized. These parameters include the number of flights, the staggering angle between sequestial kneading discs ( in degrees), direction (clockwise or counter-clockwise) and the element length (in millimeters). Except for their mixing properties, kneading elements can also be used for devolatilizing and draining of the subtance. Kneading elements with a small staggering angle are also capable to forward the material through the extruder, but therefore their axial mixing effect is less intense. In general, kneading elements with a smaller disc width provide a better distributive mixing than those with thicker discs, which provide a better dispersive mixing.

Backward-pumping elements
Backward-pumping elements give a good distributive mixin, as the name implles they transport the product upstream instead of downstream. They are used for performing a more longltudunal homogenization.
