The transport and handling of particulate solids plays an important role in many industries. For bulk material handling operations, fugitive dust has become a major concern, as it creates problems, both in the process, at the factory, and in the health of employees and the community. Since air flow and humidity are characterized as parameters associated with dust generation, it is necessary to study them to understand the problem. In this context, this work aims to present the design of a psychrometric wind tunnel, an experimental apparatus capable of carrying out tests in the laboratory of ore pile models. For this, dimensioning of each component of the wind tunnel was performed, the calculation of thermal load according to the cited bibliography, which presented acceptable results and through these components were selected to control the thermal load and the project costs were presented.
