The implementation of multiple drives for belt conveyors can solve the problems associated with motor overpower and the excessive tension of conveyor belts powered by a single drive. However, multiple drives can suffer from uneven driving power allocation. Among various factors, the selection of the type of conveyor belt particularly affects the power allocation. The current study aims to investigate the influence of the elastic modulus of a conveyor belt on the power allocation of multi-drive conveyors. Based on the Kelvin-Voigt viscoelastic model, a discrete model of an entire machine is established. Kelvin-Voigt software is used to simulate the working conditions of conveyor belts with different elastic moduli under full loads. The driving forces of individual rollers are obtained and then compared. Compared to other types of belts, a steel wire core conveyor belt, whose elastic modulus is relatively high, effectively improves the stability of the conveyor belt under a full load after start-up to achieve a reasonable power allocation. The results of this study provide a foundation for conveyor belt selection for multi-drive conveyors.

“…Regarding these conditions and constraints a value for constant k is empirically determined and applied in the algorithm for generating the reference speed of the belt on the system of five belt conveyers in an open pit mine. The results of measurements performed on the system are given in [4]. These results show that the maximum value of the material cross section on the belt is not achieved due to two reasons: the minimum speed is limited to 50% of the rated speed and the speed does not exactly follow the reduction of the instantaneous material cross section on the belt due to constant value of deceleration.…”

“…BC stations are placed along the envisaged route so that material is transferred from BC to BC several times until it reaches the final destination. The installed power of these BCs is large and each rationalization of energy consumption can provide significant savings, which is naturally of significant interest for a user [1], [2], [3], [4].…”

The paper presents a control strategy for the system of belt conveyors with adjustable speed drives based on the principle of optimum energy consumption. Different algorithms are developed for generating the reference speed of the system of belt conveyors in order to achieve maximum material cross section on the belts and thus reduction of required electrical drive power. Control structures presented in the paper are developed and tested on the detailed mathematical model of the drive system with the rubber belt. The performed analyses indicate that the application of the algorithm based on fuzzy logic control (FLC) which incorporates drive torque as an input variable is the proper solution. Therefore, this solution is implemented on the newvariable speed belt conveyor system with remote control on an open pit mine. Results of measurements on the system prove that the applied algorithm based on fuzzy logic control provides minimum electrical energy consumption of the drive under given constraints. The paper also presents the additional analytical verification of the achieved results trough a method based on the sequential quadratic programming for finding a minimum of a nonlinear function of multiple variables under given constraints

“…Equipment efficiency activities include the development of energy-efficient belting materials [11,12], application of energy-efficient motors and variable speed drives [13], and monitoring and maintenance of conveyor components based on risks of failure and expert system tools [14,15]. At the operation efficiency level, initiatives include costeffective load shifting [16], adaptive belt speed control [17,18,19], material scheduling under the time-of-use electricity tariff [3,20,21] and critical peak pricing [22], and the optimal power flow between the electric drives [23]. The impacts of the settings of certain design parameters on the future power consumption of a belt conveyor were also investigated [24].…”
