Ep 140: Sandwich Conveyors Explained: high-angle haulage up to 90 degrees
Episode 140
Wednesday, 10 December, 2025
In this episode of Fresh Thinking by Snowden Optiro, Tarrant Elkington (General Manager, Snowden Optiro) is joined by Joseph A. Dos Santos (Joe) (Dos Santos International, Marietta, Georgia) to explore high-angle conveying and the sandwich conveyor. They break down how sandwich conveyors "hug" the material between two belts to move bulk solids up steep inclines, where conventional conveying or trucking can become impractical. The discussion covers how this technology is applied in mining, what it can handle, and what to consider when comparing high-angle conveying against other haulage and lifting options. Key moments 00:01:05 – What is a sandwich conveyor? 00:02:27 – How sandwich conveyors handle extreme angles (including the "hugging" mechanism). 00:09:09 – Where high-angle conveying fits compared with truck haulage and other systems. 00:21:17 – Real-world scale example: vertical lift, capacity, and what that looks like in practice. 00:40:24 – "Mining on Mars" and why high-angle conveying comes up in off-world concepts.
