About product
Different types of screw elements can be used in a twin screw extruder. Generally there are four major types of screw elements, namely conveying elements, kneading elements, backward-pumping elements and mixing elements. For each type there are many different subtypes.
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 increases 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 there are several parameters by which the kneading elements are characterized. These parameters include the number of flights, the staggering angle between sequential kneading discs (in degrees), direction (clockwise or counter-clockwise) and the element length (in millimeters) .Â
Backward-pumping elements
Backward-pumping elements give a good distributive mixing and as the name implies they transport the product upstream instead of downstream. They are used for performing a more longitudinal homogenization.

Japan, Germany, etc. use this unit as a unit representing the performance of the sweeper, but in other regions, the input power is directly misunderstood as a unit representing the performance of the sweeper.
After reading the introduction of this article, we already know what are the characteristics of the floor sweeping robot. This kind of thing can clean the house well, especially the sundries in some dead corners. Therefore, we can choose directly according to the characteristics. In addition, the above also tells you what the principle of the floor sweeping robot is, We should use it according to what we know.
