Hello, im working in the design of a round belting belt conveyor (same design as you can watch in: KİRAZ AYIRMA MAKİNESİ (PATENTLİ) - SAKA MAKİNE İZNİK -RİZA SAKA 0532 3539039 - YouTube , for the selection of the belt diameter i want to check the worst case: two adyacent belts separated 3in and supported between idlers with a separation of 12in are loaded with 3 spherical objects with a knowed density and diameter, i want to find the belt diameter that ensures that his deflection dont let pass the spherical objects through the 3 in separation of the round belts, is this doable?, attached you can find a jpg of the assemble, right know i'm having troubles to specify the simulation fixtures, can you helpme with this??

Thanks in advance
