Diameter 85mm twin screw/Double screw for Pet fish feed extruder require.

 Φ85mm-1635mm Length 38CrMoAl-A nitriding food types twin double screw 

Like single screw, twin screw is also divided into three sections: charging section, compression section and homogenising section. There are many types of twin-screw extruders, which are mainly classified according to the rotational direction of the screws and the degree of screw engagement. According to the degree of engagement, the two screws can be divided into fully engaged type, partially engaged type and non-engaged type. Non-engaging type screw conveying is similar to single screw, generally seldom used, the application of more or full-engagement type twin-screw.
