“…can be obtained from DEM simulations. These parameters obtained from DEM simulations can advantageously be used and applied to other computational models of transport and storage applications such as, for example, a conveyor belt [20,21]. There exists research on the issue of storage processes as published, for example, in the literature [14,15].…”

This article focuses on the experimental verification of a mathematical derivation of Janssen’s theory, which describes the distribution of pressures within the bulk material and pressure distribution on the walls of storage facilities. The experimental verification is performed in two ways. The first is the real measurement of the load transfer in a bulk material cylinder and the second is similar to the detection of the load transfer through simulations using the DEM method. The aim is to compare the results of the theoretical calculation according to Janssen’s theory with the real measurement and a simulation of exactly the same model situation. At the beginning of any design or optimisation of existing transport or storage facilities, the most important is the analysis of the bulk material in the form of measurements of mechanical-physical properties. The analysis methods used are also described here. The pressure at the bottom of a storage container between the methods used showed negligible differences. From this finding, it can be concluded that the DEM method is a very suitable means for verifying the design of transport and storage facilities. The simulations provide important information and insights that can also be used to optimise existing transport or storage facilities.

“…The results showed the correctness of this method and the feasibility of belt conveyor virtual prototyping. Fedorko et al [20] resolved the problem of computation of contact forces generated by action of a conveyor belt on moulding rolls. The moulding part of the belt is analyzed during its transformation from flat to tubular form.…”

This paper is dedicated to investigating the properties of smooth conveyor belts through a tensile loading test, with the aim of examining the behavior of the inner structure of the belt samples. When the belt is subjected to a long-term strain, the belt relaxation effect is observed and changes may occur to the inner structure of the belt. The tensile test at constant velocity determines the load strength limit of the strip samples. The experiment has also shown the phenomenon of relaxation of the samples after the load. Metro-tomographic analysis is used to observe the behavior of the internal structure of the belt sample after the load. The obtained results indicate the initial damage of the inner structure of the conveyor belt occurred at the value of 2157 N. Under this load, the maximum damage size was 4.8 mm. This confirms the suitability of the method for tracking changes in the internal structure.

“… the chance that the belt may unfold, or that it may be over-tensioned, or that a corrugated surface may be caused at curvilinear sections of the path [6];  restrictions related to filling the transversal tubular cross-section with a load for not more than 75%; therefore, at the same capacity as a traditional belt conveyor, the pipe conveyor will require a belt width, which is larger by 50%;  the existence of the problem related to rotation in the pipe conveyor belt with respect to the longitudinal axis, especially at curvilinear sections means that the installation of a special means of control over the motion of the belt is required;  increased capital expenditure due to increasing the quantity of idle rollers, the large dimensions of the cylinders, and the high costs related to the conveyor belt;  the high load on the rollers crimping the tubular belt increases resistance to the belt motion along with higher consumption rates of electricity [7], [8] and [9].…”

The pipe conveyor belt design principles are considered in these pages. A method of calculation is suggested for the load on the base support rollers resulting from the bending of the initially plane belt into a cylindrical shell for the circular cross-section upon the elasticity theory with a non-uniform modulus, considering elongation and contraction variations in the elasticity modulus of the belt inserts which are positioned above and below the neutral surface at bending.
