Installations with conveyor belts can be designed simply and affordably by taking a few factors into account. In this blog, I will discuss how customers can avoid unnecessary additions which hike up the price and complicate production. Two of the most common miscalculations are an excess of shafts and tracking guides. The engineer may feel more secure about the application, but the additions will make the installation more sensitive to defects and less hygienic.
Simple conveyor design
Here are a few easy ways to ensure straightforward production:
- Avoid excessive use of shafts and tracking guides
- Don’t select an unnecessarily complex belt
- Do not install a surplus of conical shafts
I often see machines overloaded with tracking guides in simple installations for straight transport. This prevents optimum performance of the installation. In fabric conveyor belts every shaft affects the tracking. The number of these can be decreased by adjusting the design, although you must keep in mind the minimum roller diameters. Too small diameters will accelerate the ageing of the conveyor belt.
Selection of a belt with special properties and materials may lead to unnecessarily high costs. Take a critical look at the required properties and environmental conditions.
Smaller roller diameter
To avoid the use of extra tracking guides, utilize a reduced roller diameter for a smaller transfer. Many applications do not require any tracking guides when the installation is robust enough and the end pulleys have the correct shape (cylindrical or conical). The shaft width and the shape of the cone also have an influence on proper tracking.
