Something About The Diameter Ratio Of Screw Jul 28, 2018

The ratio of the diameter of the screw is the ratio of the length of the working portion of the screw to the diameter of the screw is called the aspect ratio. The diameter ratio is another important parameter of the extruder and is a major indicator of the plasticizing ability and plasticizing quality of the extruder. The national standard series stipulates that the length-to-diameter ratio L:D of the screw is 15:1, 20:1, 25:1, 28:1, 30:1, 33:1, 36:1, 38:1, 40:1, 42 :1 and so on. An extruder with a moderate aspect ratio should be selected based on raw material properties and production efficiency.
