Sectional Flight Features
Sectional flights are the main component of a screw conveyor. They are the helical component that is welded to the pipe that moves the material. There are several sectional flight features worth noting during flight fabrication, namely notches, saw teeth, serrations, and cones.
Notches
Notches are components commonly used during the initial conveying process for blending or agitation of different materials. In addition, the outer cutting is in regular intervals. Adding paddles can promote aggressive mixing, which you can use for breaking down more significant chunks of materials into smaller pieces.
Serrations
Specific applications may require brushers, cutting elements, or wear plates for the outer diameter of serrations. Furthermore, correctly positioning the cylindrical or countersunk holes is crucial to properly couple the appendages.
Cones
These cylindrical flights with a variable inner diameter promote an even drawdown in a whole hopper situation. Moreover, they are made with progressive pitches used primarily to control pressure or fill the screw feeder.
Options for Custom Sectional Flight Features
Different types of pitches
- Standard: Standard pitches with single-flight screws have an outside diameter equal to the pitch.
- Double: Double flight screws have an outer diameter equal to the pitch. It has a second set of flights that’s 180 degrees apart from the first set of flights for a more even discharge of bulk materials.
- Tapered: Single tapered flight screws can have a combination of straight as well as tapered outside diameter to meet the needs of the application. They use screw feeders, which provide uniform withdrawal of free-flowing bulk materials from hoppers, bins, or silos.
- Ribbon: Ribbon flight screws prevent the collection or build-up of sticky or viscous material due to their space within the flight and around the center pipe.
- Single-Cut Notch: Single-cut screws are notched regularly on the outer edge. It helps promote efficient mixing and agitation of bulk materials.
Materials
- Steel: A36 steel has good weldability and workability as it has a minimum yield point of 36ksi. This is the most commonly used material. On the other hand, the AR400 Steel has a minimum hardness of 360 on the Brinell scale and a nominal hardness of 400. Therefore, it is more impact abrasion resistant (AR) and a good choice for products that handle abrasive materials.
- Stainless Steel: The 304 Stainless Steel is known for being corrosion resistant and is considered the most common stainless steel used. For increased corrosion and chemical resistance, type 316 Stainless Steel has a strong resistance to pitting because of molybdenum.
- Nickel Alloys: Nickel alloys are mostly used in products that handle corrosive bulk materials as it’s not affected by corrosive materials.
Applications
Sectional flights are used in various industries for a wide range of applications. They can be found in various equipment and machinery to improve efficiency. Furthermore, sectional flights improve various operations, no matter what industry or application it uses.
