Bins are large structural elements that allow the storage of material to be fed to the comminution equipment. Due to their dimensions, it is difficult to carry out inspections since there is no access and they are usually left with dead load, which implies investing a great amount of time to clean them in order to carry out a safe work, in addition to this, the interference due to work in the vertical prevents inspections, even having problems of sacrificial plate detachment. One of the most complex components to inspect are the inserts, which is a kind of liner that is introduced into the bin discharge.
Identify technological solutions to control and diagnose in a timely manner risk situations due to wear of large bin liners and inserts. The HPGR bins are 20 meters high and 60 meters long.
The proposed solution should consider the following requirements:
The following will not be considered in the background evaluation process:
The lack of monitoring of the condition of the bin liners does not allow timely identification of the elements that require replacement due to wear.
