    Anyone interested in learning about the energy efficiency improvement opportunity from utilising larger rollers in BMH systems?

    So, we did the research and it turns out bigger is better for energy efficiency, both in terms of primary losses for IRR and Rim Drag (even if you don't specify seals). So what is holding back adoption?  What are the physical limits that cannot be exceeded by your companies / personnels requirements w.r.t. diameter, weight, volume, manual handling? is it 250mm, 20kg, 0.5m3, or can these be exceeded with automated idler installation and changeout? Keen to hear the industries thoughts. We've seen idlers up to 250mm in use, over 25kg with manual handling required. 
    Also keen to explore the shell material preferences (i.e. Steel, HDPE, Nylon, UHMWPE, Aluminium etc.) and why this preference is considered better than alternatives (ie belt friendly, light weight, abrasion resistance, carry back resistance et).
