Mpho Tshidzumba,

The answer is yes. As you increase the troughing angle, the belting becomes less pliable. The way it was described to me (take a piece of paper and roll it into a tube). The paper can support weight when rolled, but unrolled it can not. As a rule from most manufacturers, they don't reccommend a certified scale on a conveyor with 45 deg troughing idlers. ■
