safely the design of belt conveyor system involves determination of the correct dimension of the belt conveyor components and other critical parameter values so as to ensure optimum efficiency during loading and unloading conditions. some of the components are: conveyor belt, motor, pulley and idlers, rollers, pneumatic cylinder, etc.
the requirement is to design a multi-drive belt conveyor capable of transporting a certain bulk material with a flow rate of 3500 t/h over a distance of 2500 m with an inclination of 1 in 100. the description of this transportation task along with the technical parameters are listed in table 1.

conveyor belts generally are composed of three main components: 1. carcass 2. skims 3. covers (carry cover and pulley cover) carcass the reinforcement usually found on the inside of a conveyor belt is normally referred to as the 'carcass.' in a sense, the carcass is the heart of the conveyor belt since it
conveyor and t2, the take-up tension, of a conveyor belt. this ratio is of the order of 10 for a single drive pulley. this is defined by the formula: t1/t2 = eµα where: t1 = incoming tension t2 = take-up tension e = 2.718 (natural logarithm) µ = coefficient of friction on the pulley α = wrap angle of the belt on the pulley in radians
