Idler spacing will depend on a number of factors ie layout loads rates of feed belt tension etc average troughing idler spacing for run of mine ore is in the vicinity of 12 meter return idler spacing is two to three times the troughing spacing types and functions of idlers.More details research on the idler spacing of belt conveyor.Sales online.
In order to reduce the investment cost of the main incline shaft belt conveyor,analyzes the main factors affecting the cost,proposes the scheme that by optimizing the distance between idlers,to reduce the investment cost and also reduce the number of idlers.The idler spacing is usually determined by the carrying capacity of roller bearings and belt conveyor sag.Therefore,according to the main.
