Hello everyone,

I am Workin in 600x4 thermal power plant in india..we have a belt conveyor designed for carrying bottom ash via dewatering bin, the belt width is 800mm,material is nylon 66 with top cover 5mm and bottom cover 3mm, belt speed is 1.8m/s, bottom ash clinker lump size 6mm, conveying capacity Is 85 tph.i am bit new to belt conveyor systems as I never worked before on it, I am interested in knowing the calculations involved in determining the belt capacity, spacing between carrying idlers, spacing between impact idlers and trough angle suitable for conveying bottom ash, I read tht it lies in between 38 to 45degrees depending on the material and how does belt sag affects the power consumption?? ALso we have a snub pulley just after drive pulley in the return side, what should be the wrap angle, if I dont install a snub pulley, what would be the downsides, is it necessary? And yes the total belt length is 120 meters ■
