Analysis of the mechanical properties of conveyor belts on the three main stages of production

Abstract

Conveyors belts are used wherever it is necessary to transport materials quickly and promptly. They are made of fabric-rubber core (carcass) and rubber covers. The carcass may consist of several spacers made of synthetic polyamide-polyester fabrics impregnated with a solution of latex that provides an intermediate layer to prevent delamination of the vulcanized composite. The main goal of this research work is to analyse the mechanical properties of conveyor belts during three main stages of production: raw fabric, fabric impregnated with latex, and conveyor belt. For this purpose, nine fabrics of different weaves with a width of 1 m were produced with polyester warp and polyamide weft threads. The fabrics were coated with latex and then vulcanized. Subsequently, the structural parameters and the mechanical properties of each product were measured at each of the three stages of conveyor belt production. This article presents the effect of fabric structure on the mechanical properties of the products of these three production stages. Results show that differences in the mechanical properties of products at different stages of conveyor belt production depend on number of intersections of yarns in woven fabrics. In addition, significant differences were observed in the mechanical properties depending on the applied weaves.

Analysis of the pipe conveyor belt pressure on the rollers on its circuit

“…Change of the radius actually does not change the pressure on the bottom roller (4) (Figure 5(c)). The value of pressure changes when changing the arc is different depending on the weave-for fabric D, the changes are significantly higher than in the case of fabric A which has much larger rigidity [44]. This is due to differences in the bending rigidity of the individual fabrics, and, as a result, conveyor belts.…”

“…Belts of high flexibility (C, D, E, H), in which reinforcing fabrics have low rigidity (twill and satin weaves) ( Table 1) [44] show the greatest load of roller 4 (bottom) (Figure 4(b)). Depending on the belt, roller 4 was more or less loaded to rollers 3 and 5.…”

Design of a Calculation Fem Model of the Test Static Stand of Pipe Conveyor for Analysis of Contact Forces

“…This trend of research in the field of pipe conveyors has been gradually attenuated, and at present particular researchers attempt to scrutinise detailed problems related to conveyor belt operation [3,4]. This fact is more noted above all in recent years when the attention is focused on the research into the characteristics of conveyor belts, as found in Baburski [5], who studied in more detail the mechanical properties of rubber-textile conveyor belts. Others, who dealt with the research of pipe conveyors, Will and Staribacher [6], focused on the research of material conveying on long distances and also studied the characteristics and behaviour of conveyor belts.…”

The use of industrial metrotomography in the field of maintenance and reliability of rubber-textile conveyor belts in closed continuous transport systems

“…Another significant field of research concerning tubular conveyor belts is the behaviour of a transporting belt. Baburski [3] analyses the mechanical properties of conveyor belts at three main stages of production. In his other research, he investigated the effect of pipe conveyor belt pressure on the rollers on its circuit [4].…”
