The Importance of Screw Conveyor Flights

Screw conveyor flights play a crucial role in the operation of screw conveyor systems, contributing to the transportation and lifting of materials.

They are responsible for generating the necessary torque to move materials from one point to another.

Learn About Common Types of Screw Conveyor Flights

Screw conveyor flights can be classified based on several factors, including shape, size, and function.

Each type of flight offers unique advantages and is used in different applications.

Below is a list of 12 common types of screw conveyor flights. Each type has its own pros and cons, and the choice depends on your specific application needs.

Standard Pitch – Single Flight

This is a screw conveyor flights with a pitch equal to the screw diameter. It is widely used in most general applications.

Standard Pitch – Increasing Diameter

This type of flight features a gradually increasing diameter from 75% to a full 100%. It is commonly used to uniformly convey and mix materials.

Short Pitch – Single Flight

This type of screw conveyor flights has a pitch equal to 75% of the screw diameter. Commonly used in inclined or vertical screw conveyors.

Standard Pitch – Cut Flight

This type of single flight has a standard pitch. It provides strong agitation and mixing of materials during conveying.

Extra Short Pitch – Single Flight

A screw flight type with a pitch equal to only half of the screw diameter. It is typically used for conveying extremely fluid materials.

Standard Pitch – Cut & Mixing Flight

This screw flight is welded with an additional mixing fin to slow down material fall. It is also used for light stirring, loosening, and reducing material temperature.

Wide Pitch – Single Flight

This screw flight has a pitch 1.5 times the screw diameter, making it ideal for mixing liquid materials or rapidly conveying bulk materials.

Standard Pitch – Mixing Single Flight

This is the best screw conveyor flight for conveying and evenly mixing sticky or viscous materials. The large clearance between the flight and the shaft helps prevent material build-up.

Variable Pitch – Single Flight

A screw flight with progressively increasing pitch along its length. Used as a feeder screw to evenly deliver fine, free-flowing materials across the entire inlet length.

Standard Pitch – Double Flight

A screw with two standard-pitch flights mounted symmetrically. Provides smooth, consistent, and uniform material flow for certain types of materials.

Mixing Ribbon Flight

A ribbon-type mixing flight designed to provide optimal mixing and agitation of the material flow.

Standard Pitch – Shaftless Flight

Shaftless screw flights are self-cleaning, helping reduce clogging and maintenance.

Choosing the Right Screw Conveyor Flight

Selecting the appropriate type of screw conveyor flight depends on various factors such as material type, load, conveying speed, and working environment.
It’s essential to clearly define the application requirements to ensure optimal performance.
