Screw conveyors are widely used in various industries for the efficient transportation of bulk materials. One critical component of a screw conveyor is the pitch of the screw, which plays a vital role in determining the conveyor's performance and efficiency. In this article, we will focus on the standard pitch of screw conveyors, particularly single flight screws with an outside diameter equal to the pitch. This type of screw is commonly used for horizontal screw conveyors and inclines up to 10 degrees.

Standard pitch, single flight screws have the outside diameter equal to the pitch and are the most common screw type used for horizontal screw conveyors and inclines up to 10-degrees.

Conveyor Pitch Types Chart

When it comes to screw conveyors, the pitch of the screw refers to the distance between adjacent flights along the length of the screw. The pitch can vary depending on the specific application and material being conveyed. In the chart below, we outline the different conveyor pitch types commonly used in the industry:

1. Standard Pitch (Single Flight): Outside diameter equal to the pitch, suitable for horizontal conveyors and inclines up to 10 degrees.

2. Variable Pitch: Flights with varying pitch along the length of the screw, allowing for better control of material flow and mixing.

3. Inclined Screw Conveyor: Specifically designed for conveying materials at an incline, typically more than 10 degrees.

4. 6 Pitch Conveyor Chain: A specific type of conveyor chain with a pitch size of 6 units, commonly used in industrial applications.

Conveyor Pitch Types

The pitch of a screw conveyor can have a significant impact on its performance. Different pitch types are used based on the material properties, flow characteristics, and operational requirements. Let's take a closer look at some common conveyor pitch types:

1. Standard Pitch: As mentioned earlier, single flight screws with an outside diameter equal to the pitch are considered standard for many applications. They provide good material handling capabilities for horizontal and slightly inclined conveyors.

2. Variable Pitch: In applications where precise control of material flow is required, variable pitch screws are used. By adjusting the pitch along the length of the screw, operators can optimize the conveying process for different materials and operating conditions.

3. Inclined Screw Conveyor: When dealing with materials that need to be conveyed at an angle, inclined screw conveyors are the ideal choice. These screws are designed to handle the challenges of conveying materials uphill or downhill efficiently.

Conveyor Chain Pitch Chart

In addition to screw conveyors, conveyor chains are another essential component in many material handling systems. The pitch of a conveyor chain refers to the distance between the center of one link to the center of the next link. The pitch size is crucial for determining the chain's strength, speed, and overall performance. Here is a sample conveyor chain pitch chart:

1. 6 Pitch Conveyor Chain: A common pitch size used in various industrial applications, the 6 pitch conveyor chain offers a balance between strength and flexibility. It is suitable for medium-duty conveying tasks.
