• Abstract:

   Pará has one of the largest mineral reserves in the world, establishing itself as one of the main producers and exporters in this segment. With the resumption of investments in the sector and due to the need to transport ores over long distances, it is observed that the use of conveyor belts in the mining and metallurgical sector has been an appropriate solution for moving large volumes of material, reducing truck traffic. and the cost of this type of service, which has a production capacity of an average of 430 tons per month. Therefore, with this information in mind, a case study was carried out in a conveyor belt manufacturing industry, with the aim of using Industrial Production Management tools to increase productivity and reduce the rate of downtime due to equipment breakdown. With these tools in use, it was possible to identify, analyze and apply improvements to the main equipment in the production process, such as the implementation of the preventive maintenance plan, mapping of critical equipment, development of new components and suppliers, resulting in an increase in reliability of operation (23 hours) which was previously from 12.53% to 139.05%, the increase in Mean Time Between Failures (MTBF) from 37.73 hours to 87.71 hours, with cost reduction and elimination of waste and reworks.
