High Efficiency Single Screw Extruder easy to use

Single screw extruder into the series development period

Compared with other extruder, single screw extruder has the characteristics of simple structure, durable, easy to repair, low price, simple operation and so on. There is still a long mall in our country for a long time. How to make the conventional single screw extruder Excellent, efficient, multi-functional, is still China's plastic industry to carry out the arduous mission.

With the joint efforts of the industry, the development of the staff, some of the most important special models such as exhaust extruder, tandem mill screw extruder, reciprocating pin screw extruder, foam extruder, with a melt gear pump Of the extruder, series multi-stage extruder, planetary screw extruder, etc. are produced in the domestic manufacturers, with the independent development of the ability and enjoy independent intellectual property rights, and now has entered a series of development period.

The disc extruder is a suitable high-filling material mixing equipment. Twin-screw extruder for glass fiber reinforced compounding, if the glass content exceeds 45%, processing will become appropriate and difficult. Magnetic material magnetic powder content is generally as high as 60% to 70%, sometimes even up to 90%, with the general extruder for magnetic processing and granulation is almost impossible. Some domestic manufacturers and research institutes, according to the domestic magnetic data and other high-filling materials needs, dedicated research announced the independent planning of the disc extruder. Typical examples such as Beijing Fengji and Beijing University of Chemical Technology. The disc extruder can be adjusted by the combination of discs to accustomed to not the same high filling materials, such as glass fiber reinforced, magnetic plastic, conductive materials, new ceramic materials such as extrusion processing.

Reciprocating screw extruder in recent years, the domestic shopping malls a moment, but also become different manufacturers show the strength of a symbol of the goods. The biggest feature of the reciprocating single-screw extruder is the completion of the high-filling process of the same material. For glass fiber reinforced materials processing, the increase in glass fiber can reach more than 50%. Nanjing Rhea company in the nineteenth World Rubber and Plastic Exhibition during the special display of the WXJ-120 reciprocating screw extruder, according to the introduction of the largest domestic reciprocating extruder. Although China's extruder shopping malls to carry out rapid, there are many new models introduced, but we can not ignore our extruder skills and foreign developed countries there is a greater distance.

Selection of new extruder screw, barrel structure and supporting system satisfaction with shopping malls

For the extruder equipped with a new screw, barrel structure and exhaust system is to complete the power forward, reduce energy consumption of the useful way. For example, the use of higher aspect ratio of low shear screw, the choice of slotted barrel, the choice of more efficient exhaust system are useful methods.
