Belt Conveyors for Bulk Materials Practical Calculations

Therefore, the belt length correction is: C = L c L 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 =

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.
