The present work addresses the need of improving the availability of the roasting plant by the review of the processes, the failure modes of the machines involved and the parameters that can exceed the established values such as: Feeding rate of 47 Tn/hr, daily production of 1128 Tn/day, bed resistance from 180 mbar to 190 mbar, primary air injection of 80000 Nm3/hr, secondary air injection of 5000 Nm3/hr and finally the bed temperature range from 900°C to 950°C. To achieve this goal, Six Sigma methodology has been used to reduce the variations of the processes that lead into the unachivement of those goals. In the first chapter we will see the backgrounds that leads into the implementation of the present work, also the theory of the tools used for accomplished the goal and their relation with the problems identified. The second chapter describes the organization of the company. Later, technical analysis is based to identify the problem and the economic impact. Finally, the causes that lead into the problems are analyzed as well as the work objectives. In the third chapter, the engineering proposal that will lead to the solution is described, also all the details will be shown. Finally, in chapter four, the results of this Project will be shown with the evaluation of the economic and non-economic impact.
