Substantiation of the Operational Parameters of the Sandwich Belt High Angle Conveyors with due Regard for Strain Deformed State of Belts

The article deals with the advantages of special types of conveyors and, in particular, the sandwich belt high-angle conveyors, and also several problems appearing when designing and creating high-productive installations under high conveying angle and to considerable height. Processes of overstrain of separate sections of the belt and also considerable deformations of edges and the middle of the belt are established in the article. It is shown that an effective method of the solution of such tasks is the modeling of strain deformed state of belts with utilization of methods and the software application of the ANSYS complex. Decision examples for separate sections are given in the article too. The role of elastic properties of the belts and their durability when basing parameters of the considered sections is proved in the article. It is shown that modern rubber fabric and rubber cable belts give the chance of creation of powerful conveyor installations with a cover belt for large conveying angles and high productivity.
