Mining and pelletizing

Innovation in favour of agility

We offer solutions for various areas of mining and pelletizing plants, and we develop joint computer simulation work for optimized drying curves. Our experience from drying and heating to cooling and thermal comfort in the most diverse equipment:

Specifically for pelletizing furnaces, uniform heating in all chambers is important and challenging. With a division dedicated to the development of technology, Æstus, we developed a method that allowed 50% reduction of downtime. We are proud that our method is today applied to the largest pelletizing units in the world.

Quanto às operações de resfriamento, desenvolvemos, numa operação específica, procedimento que resultou numa redução de mais de 24 horas no tempo de resfriamento, com relação ao método habitualmente praticado.
