Next it is important to calculate T2 sag (slack side tension required to prevent belt sag.) Sag is a phenomenon which can occur at the point of minimum tension in the carrying strand of a conveyor belt. On an inclined conveyor, it is usually in the vicinity of the loading zone.

Read MoreJun 11, 2016 Dear all, I was working on belt profile and noticed that the equation for belt sag is not consistent with the equation for belt profile between idlers. At first I believed that between idlers belt curve must be relatively small at idlers and relatively large between them (like below image). 45175 That was true till I read a paper on the mechanism of slip and material fall back, where the ...
Read MoreBelt 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.

If the conveyor belt is under-supported on its return side, the weight of the belt in that section is supported by the pulleys as a catenary load, and greater belt tension is needed to prevent excessive sagging. Belt return support rollers should be spaced so that the belt does not sag excessively between each roller.
