With the ultimate objective that the belt gently sandwich and convey the material within the geometry restrictions of the conversion, the client chose Rulmeca idlers sets and custom rollers to suit their unique carrying and hold-down frame requirements. Timing of the project dictated supply chain challenges that needed to be overcome, as the initially requested CEMA E7 rolls were not readily available to meet the project schedule. Rulmeca partnered with Dos Santos to designand supply foot spacers to compensate and match the client’s desired belt line, and we were able to substitute CEMA E 6-inch diameter rolls to eff ectively match the performance needs of the system within the project schedule.
