Aiming at the deficiencies in the catenary theory of the conveyor inter-roller sag, the elasticity modulus of conveyor belt was introduced for establishing the elastic catenary parameter equation of the inter-roller conveyor belt in consistency condition and the analytical solution to the maximum inter-roller sag was derived based on the analysis of the current inter-roller sag equilibrium equation, and whose correctness was verified by the case analysis and simulation research. According to the research result, the maximum inter-roller sag of the conveyor belt is in non-linear reciprocal relation with its elastic modulus, in nonlinear quadratic relation with inter-roller gap, and also in nonlinear relation with conveyor belt tension while the greater the tension is, the smaller the sag will be. Meanwhile, the minimum tension under the relative sag and its restriction was further developed on the basis of elastic catenary.
