The reliability of travel motors used in bulk-material-handling equipment is fundamental to ensuring the operational availability of ore-handling systems in continuous-operation industrial environments. This work…
Alan Souza Da Silva
This work presents the results of studies conducted through reliability analysis and scenario simulation. The application area is a filter press, where the objective was to increase asset useful life tenfold.
Alexandre Angelo Ferreira Grossi
This article explores the loss profile associated with established statistical models in the literature and with reliability in industrial systems. Reliability is a critical factor for operational efficiency and cost…
Bruno Mendonca Justo
The study presents a detailed Reliability, Availability and Maintainability (RAM) analysis in a mining operation based on treatment of an extensive database containing more than 1,000,000 corrective- and…
Christiano Calijorne de Barros
In recent years, Vale has experienced several cases of tire bursts on off-highway trucks. Bursts and explosions are events in which the tire structure ruptures, causing a sudden release of the energy contained inside…
Dales Martins
This project, developed by the Reliability Engineering Coordination team, began in 2024. Its main objective is to reduce fuel consumption in diesel engines, improve operational efficiency and promote sustainability.
Gabriela Nascimento Queiroz Carvalho
Application of Artificial Intelligence and Machine Learning to integrate the main maintenance indicators — Physical Availability, MTBF and MTTR — into a single index: ICM, the Maintenance Reliability Indicator. The…
Gilberto Barbosa Lima Filho
Analysis of plant bottlenecks through reliability, availability and cost calculations to identify critical assets. After identification, RCM is applied to the maintenance strategy.
Guilherme de Souza Paiva
Positive-displacement pumps are the main equipment in a slurry-pipeline transport system and are therefore extremely important to the flow of iron ore at Samarco Mineração. Because of the criticality of these assets…
Ighor Caetano Silva Ferreira
In response to production demands, companies have invested in maintenance to preserve equipment, reduce costs, lower failure rates in physical assets and increase machine availability. This in turn improves…
Ivan Guillermo Garcia Villafane
Dozer blades are essential components in mining, construction and earthmoving operations and are subject to severe wear due to continuous abrasion and impact with the ground. This study proposes a liner-sizing method…
João Victor Damasceno Pereira
The article addresses development of the SGO at Bracell, highlighting its application to reliability analysis. The tool centralizes records, calculates indicators and optimizes decisions, with a case study in the Wood-Chip Preparation area.
José Marcelino Andrade Barros Júnior
This work describes a project to optimize the useful life of differentials in a CAT 797F off-highway truck fleet at a copper mine in Pará. The study focused on quantitative reliability-analysis techniques to improve…
Lucas Akira Nogueira Yokoyam
This article analyzes how regulatory changes introduced by NR12 affect the ability of industries to predict failures in their machines. It discusses the additional complexities generated by updated safety…
Milena Brenda Barros Gomes
The Estrada de Ferro Carajás currently has more than 1,000 industrial assets. Chip conveyors are classified as Class A assets by Reliability Engineering because of their importance in the maintenance process for the…
Renato Cesar Ribas Peres
The work was developed to create reliability curves and define useful-life time in hours for hydraulic cylinders used in a fleet of heavy mining machines. This LDA analysis, grounded in reliability, provides…
