26-02-2020· 1. idler spacing Selection for bulk material belt conveyor. The belt conveyor is used to transport bulk materials has a distance between the supporting idlers about 0.8-1.5m and a distance of the return idlers of the rollers of about 2-3m. 2. Idlers spacing Selection for overland belt conveyor. For long-distance belt conveyors (overland belt ...
22-01-2013· The diameters in millimeters of carrying and return idlers shall be selected from the following: 63.5, 76.1, 88.9, 101.6, 108, 114.3, 127, 133, 139.7, 152.4, 168.3, 193.7. The spacing of idlers on the loaded run of the conveyor, carrying bulk material, depends on the belt width, the specific weight of the bulk material, the type of the idler.
Troughing Idler Spacing. Idler spacing will depend on a number of factors, i.Layout, loads, rates of feed, belt tension.Average troughing idler spacing for run of mine ore is in the vicinity of 1,2 meter.Return idler spacing is two to three times the troughing spacing.Types and functions of idlers.

Normal spacing is 3 to 5 feet . ... Troughing idler load ratings (Tables 5.7–5.10) are for three equal length rolls. 2. Load ratings also apply for impact rolls. 3. Troughing idler load ratings are based on a load distribution of 70% on center roll and 15% on each end roll for all trough angles. 4.
Si = troughing idler spacing. Tac = total of the tensions from conveyor accessories. Tam = tension required to accelerate the material continuously as it is fed onto belt. Tb = tension required to lift or lower the belt. Tbc = tension required to overcome belt cleaner drag.
