Conveyor belts are constantly subjected to longitudinal forces, to the weight of the material between the idlers and to the impact of the material on their upper face, so they must have special design features for their resistance. However, eventually longitudinal and transversal tears occur, which may have different causes, such as: incrustation of external objects or fragments of coarse ore, steel cables cutting, deformation of joints, failure of idlers and sheaves, misalignment, overvoltage, friction, among others. These tears must be detected in a timely manner to avoid major damage and minimize downtime for repair.
Identify solutions or technological developments that allow the timely detection of tears in the main conveyor belts of the crushing plant. The scouting process could lead to identify and select suppliers for a competitive process of supply or purchase, whose scope will be defined according to the degree of maturity level of the proposals that apply to the open innovation process, which could give rise to a pilot validation test, or to an implementation if they are relevant and meet the evaluation and selection criteria defined by Codelco
Currently, the inspections carried out on the belts are visual inspections during plant shutdowns, i.e. partial inspections. This means that the belts are not inspected in their entirety and therefore the information that would allow to anticipate a major failure is insufficient.
In an eventual and unanticipated manner.
