Good day Members,

I've had a reasonable exposure to the design of conveyor belts, and I'm faced with a new challenge. I need assistance with regards to the design of horizontal curves. I have not been able to find insightful information regarding this topic yet (or rather I have not be looking in the right places). I'm really just looking for information that will provide the basics/fundamentals of horizontal curve design. I would greatly appreciate any articles, research papers, etc, that you can recommend/provide regarding this matter. Thanking you all in advance.

Regards,

Mark Alspaugh of Overland Conveyor Inc. explains the principles of horizontal curve design very well in this video link below. The video is based on using Overland Conveyor's software Belt Analyst Suite.

If you have any questions about the Belt Analyst software let me know. ■

Lyle,

I've looked through that paper that you suggested. I seem to understand most of it, but i have an issue with one of the equations, particularly with the calculation of the Fgb and Fgg forces. I re-sketched the force diagrams for the forces resulting from the belt and the material over each idler. I found that the actual radial force due to the belt and the materials should include a cosine component as an addition to the sine component as expressed on the equations for both Fgb and Fgg. For example, the Fgb force would then be expressed as:

Fgb=(Gb*It)/B [SB1*sin(+Y)cos(+y)+Im*sinycosy-SB2*sin(-y)cos(-y)]; similarly for Fgg as well

Would this be correct?

Thanks. ■

I have been been unsuccessfully trying to make time to sit down and complete my own FBD (just for kicks), though due to various reasons, this looks unlikely.

Hopefully the following assists in lieu:

There is another paper, that may be of use, though I could not find in the public domain:

GRIMMER, K.-J. and KESSLER, F.

The Design of Belt Conveyors with Horizontal Curves. Bulk Solids Handling, 12 (1992), No.4, pp.557-563

There has been previous discussions regarding this subject on this forum, which may be of use.

Lyle ■
