Belt conveyor is widely used in a variety of automated production lines and bulk material transportation is one of the most important applications. In order to improve the accuracy of the belt conveyors, it is need not only to strictly control the production crafts, more importantly, to improve the rationality of the structure and design level. Running deviation and adjusting deviation problem are important issues to be considered in a belt conveyor design process. In this study, the 3D synchronous technology of Solid Edge ST4 will be applied in the design of the belt conveyor to design a new type of anti-deviation structure. In the design process, we combine the synchronous technology with modular technology and top-down assembly modeling techniques to confirm the subject and adjust deviation. The key is the application of synchronous technology in 3D design and the new structure in Running Deviation and Adjusting Deviation. It turned out that the application of above technology can reduce design errors and avoids the repeated design, thus greatly improving the efficiency of the engineer's design. Meanwhile, the study of running deviation can make the structure of adjusting deviation come true.

Differential tensioning devices for belt conveyors in general and intermediate drives of extended conveyors in the form of closed traction loops are a new type of automatic tensioning devices that differ from other known designs by the presence of a stepwise discrete belt tension control system with separation of compensation functions for belt stretching under load and control of its tension during the operation of the conveyor in order to create optimal modes of belt loading. The article analyzes the well-known and practical concepts of belt conveyor control systems in general. The possibility of controlling the traction force realized by the intermediate belt drive by controlling the tension of the traction and load-carrying belts is shown. On the basis of the analysis, conceptual solutions for control systems for differential tensioning devices of belt conveyors are proposed with the possibility of both autonomous use and application in the structure of an integrated conveyor control system. Possible structures of linear parts of differential tensioning devices are presented, as well as options for the implementation of executive parts that directly move tensioning elements.

Currently, the widespread use of tubular belt conveyors is constrained by insufficient justification of the conveyor parameters. In the work, on the basis of the theory of the limiting equilibrium state of bulk load, equations of equilibrium of load on the belt of an inclined tubular conveyor are obtained. It is assumed that the belt was a rigid cylinder filled with bulk material in extreme equilibrium. Based on the obtained equilibrium equation, the analytical dependences of the limiting angle of inclination of the belt conveyor with a tubular belt on the degree of unfilling with the bulk load of the belt and the properties of the bulk load are found. From the analysis of these dependencies it follows that the limiting angle of inclination of the tubular belt conveyor depends on the angle of internal friction of the transported load, the angle of friction of the load on the conveyor belt, the angle of unfilling of the belt with load and does not depend on the radius of the conveyor belt.

Belt Conveyors

Belt conveyors (BCs), because of their high efficiency, are widely used for bulk material handling in the mining industry. However, due to the high level of conveyors’ energy consumption, the belt conveyor systems generate a large part of mining costs. Therefore, the current solutions mostly focus on implementing new management strategies, which find energy consumption as a key indicator in designing belt conveyor systems. Belt conveyor equipment selection, conveying systems, operation, applied mining technology are considered to be areas where improvement of belt conveyors’ energy efficiency may be achieved. Moreover, they can be used to implement novel standards for BC equipment and the proposal of defining new quality standards and creating BCs’ classification has been already outlined. The main idea of the paper is to compare the values of specific energy consumption (SEC) of BCs with regard to the inclination angle of a conveyor route which results from technological needs. The multiple regression is used to find a relationship between two basic independent variables – the volume of transported material and conveyor’s inclination angle – and a dependent variable (SEC). The procedure enables to determine the value of SEC which is required for lifting the material. Presented results prove that the value of SEC required for lifting the material is crucial for the interpretation of the SEC value when it comes to energy efficiency comparison.

Belt Conveyors

Conveyor belts are key pieces of equipment for bulk material transport, and they are of great significance to ensure safe operation. With the development of belt conveyors in the direction of long distances, large volumes, high speeds, and high reliability, the use of inspection robots to perform full inspections of belt conveyors has not only improved the efficiency and scope of the inspections but has also eliminated the dependence of the traditional method on the density of sensor arrangement. In this paper, relying on the wireless-power-supply orbital inspection robot independently developed by the laboratory, aimed at the problem of the deviation of the belt conveyor, the methods for the diagnosis of the deviation of the conveyor belt and FPGA (field-programmable gate array) parallel computing technology are studied. Based on the traditional LSD (line segment detection) algorithm, a straight-line extraction IP core, suitable for an FPGA computing platform, was constructed. This new hardware linear detection algorithm improves the real-time performance and flexibility of the belt conveyor diagnosis mechanism.

Belt Conveyors

Belt conveyors are generally used in mining plant areas, both surface and underground mines. The belt conveyor is mainly applied to transport the extracted bulk material from the mining site to delivery. The effectiveness of the extraction process depends on the reliability and durability of the conveyor belt system. In addition, conveyor performance is very important specially to control material flowability to prevent spills or other operational disturbances to optimize production throughput. However, the transfer chute and settling zone can cause some problems during the transfer process, such as material spills. This problem can reduce the function and performance of the conveyor belt. This paper discusses a design model to reduce the problem of spillage in the settling zone. The model was developed by compiling the previous defecting data from the durability of the conveyor system, then analyzed using Discrete Element Method (DEM) software and compared with bulk characteristics. The initial performance of certain conveyors is only capable of serving with an average production of 76% of the designed capacity while energy is consumed at full load. By applying the DEM simulation result, the blade gate can reduce the peak angle break in the depositional zone before exiting. After the analysis is completed using DEM, the conveyor increases the average production to 95% of the designed capacity. In conclusion, controlling the maximum belt load without spillage will reduce interruption on conveyor belt operation and maintenance costs therefore increase plant reliability and availability.
