What is the Outer Diameter Range of Continuous Auger Flights?
Continuous auger flights are defined by length. They are long, generally multiple times the length of the pitch. Continuous auger flights are produced by auger flight cold rolling mills. The feeding is steel strips by cutting to be a certain width. This can avoid the waste of steel raw materials and better control the length. According to the length of the spiral flight conveyor, continuous auger flights can also be produced to the corresponding length, but they are generally cut into two meters for easy transportation and installation.
The outer diameter of continuous auger flights has certain limitations. Because the roller processing length on the production equipment—auger flight cold rolling mill is limited, the outer diameter range of continuous auger flights is determined by the processing range of the auger flight cold rolling mill. The general outer diameter range is 100-500mm. In addition, the outer diameter of the auger flights has a certain relationship with the processing steel strips width. When the steel width does not exceed the processing range, the inner hole is larger, the outer diameter is more larger. Usually the inner hole can be within 500, and the outer diameter range is less than or equal to 780mm.
There is also another kind of continuous auger flights with equal thickness. The outer diameter range of this auger flight is very small. Due to different processing methods, the processing method of the continuous auger flight with equal thickness is to rotate the flights molds with each other, wrap the steel strip inside the mold, and use external force to form the steel strip into a auger flight shape. The processing of the flight mold is not like that of the continuous auger flight cold rolling mill. The outer diameter cannot be infinitely large. The size of the outer diameter is determined by the diameter of the mold, generally within 200mm.
