Factory Nameplate And Main Parameters Of Twin-screw Extruder

In the following articles, the main parameters of the twin screw extruder, screw action, external thread components, extrusion process temperature, extruder screw speed ratio and other aspects are introduced in detail. Please follow Xiaobian carefully read these articles, after reading will have a very in-depth understanding of the extruder!

It is important to understand the extruder number and specification parameters, such as: SHJM-Z40×25×800 extruder, what does it mean?

The results show that the screw diameter is 40mm, the height diameter is 25, and the drag roll length is 800Mm.

Meaning of factory nameplate

1, "SH" is the type number, refers to the twin screw compound (also written: SHSJ, SJ refers to plastic extruder);

2, "J" is the grade number, referring to the extruder;

3, "M" refers to the type number, refers to the injection plastic film machine;

4, "Z" refers to the auxiliary number, refers to the key generator set, and if "F" refers to the auxiliary machine;

5, "40×25×800" refers to the specification parameters, the diameter of the finger screw is 40mm, the height diameter is 25:1, and the length of the traction roll is 800Mm;

6, the final one for the manufacturer identification number, generally does not appear, is omitted.

There are many main parameters for the qualitative analysis of the characteristics of extruders and screws, and many more common index values are as follows:

1, "D" is the diameter of the screw, considering the extruder production size of a key main parameter;

2, "L/D", refers to the proportion of screw length and screw diameter, immediately harm the melting degree, is to consider the main use of the mark, general plastic modification production and processing, with 30-60 up and down, common 35:1, 40:1 or 44:1;

3, "H", deep spiral groove, refers to the size of its material space;

4, "e" edge thickness, processing technology reflected in the size of the shear;

5, the gap between the "6" screw and the barrel, a key main parameter of the extruder quality, is generally 0.3-2 mm, and the extruder is the alarm line after turning 5 mm;

6, "N" server speed ratio, refers to its maximum value, refers to a production and processing adjustment scope, great harm to the production volume and the division of advanced low speed;

7, "P", motor rated power and heating output power.
