Belt Widths The belt widths are as follows 18 24 30 36 42 48 54 60 72 84 and 96 inches The width of the narrower belts may be governed by the size of lumps to be handled Belts must be wide enough so that any combination of prevailing lumps and finer material does not load the lumps too close to the edge of the conveyor belt
All conveyors require an additional belt tension in order to allow the pulley to drive forward an effective tension without slipping In a case of a simple horizontal conveyor T1 is the sum of the effective tension Te and the slack side the tension T2 T 1 = T e T 2 = For the inclined conveyor additional tensions are induced due
