Twin-screw pelletizing machine service provider Cromwell staff said the structure type of the twin-screw pelletizer system varies according to the scope of application and operating characteristics. The screw prongs of one screw are like wedges into the screw groove of the other screw, and the material usually cannot enter the neighboring screw groove continuously from the screw groove, but only flows from the screw groove of one screw to the screw groove of the other screw as a last resort.

Single-screw pelletizing machine wanrooe machinery staff said the extrusion of heat-sensitive raw materials, such as PVC pipes and profiles, special polymer processing, such as blending, exhaust, chemical reactions, etc. Compared to single screw, twin screw pelletizer has much better feeding and conveying performance, especially those difficult to feed and easy to slip, such as fibrous, powdery and greasy materials. The material retention time is short and more homogeneous, with better mixing and a relatively large heat transfer area, so that the material temperature is well controlled, which is essential for the processing of heat-sensitive raw materials.

Twin-screw pelletizing machine installed head and shaped set, based on commodity varieties, and sizes, choose a good head specifications model, in the following order of priority will be installed head.

1, the head should be assembled in one piece and installed on the pelletizer as a whole.

2, Before assembling the head, it should be cleaned off the grease applied during storage, carefully check whether there are bruises, scratches and rust spots on the surface of the cavity, polish accordingly, and then apply a layer of silicone oil on the surface of the runner.

3, Arrange each plate of the head in order to assemble in one piece, apply high-temperature grease on the threads of the bolts, and then screw on the bolts and flanges.

4, Place the porous plate between the flanges of the head to ensure that the porous plate is pressed without overflowing material.

5, Before tightening the bolts of the connecting flange between the head and the twin screw pelletizing machine adjust the level of the die, you can use the level to adjust the level of the square head, the round head is based on the bottom edge of the fixed model rubber with the bottom edge of the head die correction.

6, Tighten the connecting flange bolts, tighten the head fastening screws, assemble the heating ring and thermocouple, and pay attention to the heating ring and the head surface tightly.
