Steel cord conveyor belts. Determination of the lateral and vertical displacement of steel cords

Conveyor belt is an important element of the conveyor. The strength of the steel cord conveyor belt largely determines the carrying capacity, and it also has a great impact on operational safety. In this paper, the effect of different factors on the strength of the steel cord conveyor belt splices was studied. The FEM was used for simulation analysis, and the corresponding tensile experiments were carried out to verify. Steel cords of different lengths were simulated, and the simulation results agree well with the experimental results. On this basis, the steel cord length, steel cord diameter, rubber thickness, and different number of steel cords were investigated to study the effect on the pullout force of the steel cord conveyor belt splice. The numerical simulation results show that different steel cord diameters have more significant effect on the strength of the conveyor belt splice compared to rubber. The steel cord length and steel cord diameter impact on the steel cord conveyor belt is approximately linear. For the different number of the steel cords, the increase in the number of steel cords does not mean that the tension will increase by the same multiple, and the increase in pullout force is less than the increase in the number of steel cords. It provides guidance for the production of steel cord conveyor belts.

Steel Cord

Abstract Brass-coated steel cords are extensively used as reinforcement material in radial tires, high-pressure hydraulic hoses and heavy duty conveyor belts. Bonding between rubber and steel cord is obtained via the formation of an adhesion interface layer during the curing process. The adhesion build-up mechanism involves the chemical reaction of sulfurating species contained in the rubber skim compound and copper of the brass coating, forming a CuxS layer at the rubber-brass interface. Advances in mechanistic investigations are presented, using analytical techniques such as X-ray photoelectron spectroscopy (XPS), Auger electron spectroscopy (AES), atomic force microscopy (AFM) and optical microscopy (OM). XPS and AES provide chemical in-depth information, whereas OM and AFM highlight the morphology of the resulting interfacial layers. These investigations improve the understanding of the adhesion mechanism, both for adhesion buildup and for bond degradation.

Strength And Durability

A new eco-friendly method of splicing steel cord conveyor belts without the use of noxious materials has been developed by the Mining Institute at Wrocław University of Technology in collaboration with the Bełchatów Lignite Mine – the two leaders in implementing state-of-the-art and environment friendly technologies in mining in Poland [1,2,3]. Polish lignite mines use belts with steel cords. Such belts are spliced through high temperature vulcanization, which is not safe for the environment and has an adverse impact on human health. Strength and durability are the two main properties of belt splices, having a bearing on the failure-free operation of the belt conveyors used for the haulage of stripped rock or muck in open pit mines [4,5,6]. This means that properly made steel cord belt splices should have the strength and durability parameters similar to the ones of the belt without splices. Many factors contribute to the quality of the splice, including the ones connected with the splicing technology, workmanship and with the fact that splices are made directly on conveyors in heavy mine conditions.
