Faena: Chuquicamata Division
Deadline 20/06/2023
Closing Time 4:00 pm
Currently, in the crushing plant of Codelco – Chuquicamata Division, wear liners are used in hoppers and chutes consisting of steel plates with a maximum weight of 25 kg to comply with current regulations for manual material handling. These plates are subjected to abrasion and permanent impact from the ore being processed and therefore have a maximum life of approximately 3 months, with a throughput of between 5 and 15 million tons. In addition, the frequent stoppages for the replacement of these linings imply risks, both of accidents to the people who perform the maintenance work, as well as for the fulfillment of the production plans.
Identify technological solutions or alternative products to conventional steel linings that allow for increased performance and rapid installation. Proposals for new materials or alloys of lower density than conventional steel plates are expected. The scouting process could lead to the identification and selection of suppliers for a competitive supply or purchase process, the scope of which will be defined according to the maturity level of the proposals that apply to the open innovation process, which could lead to a pilot validation test, or to an implementation if they are relevant and meet the evaluation and selection criteria defined by Codelco.
According to current regulations, the current steel linings of the chutes and hoppers in the crushing plant can have a maximum weight of 25 kg, which only allow a useful life of 3 months, equivalent to a performance of between 5 and 15 million tons.
Permanently.
Conventional 25 kg steel plates and replacement every 3 months approx.
No new technologies have been tested.
