Smoke and dust exhaust from sand casting plants

The process of making sand for foundries involves a series of complex equipment, each with its own specific role. From the sieves that separate the granules, to mixing drums and shredding mills, each stage contributes to obtaining an optimal quality sand.

The handling of this fine material, however, generates unique challenges. Especially in the mixing and grinding areas, the sand can become extremely wet, complicating the filtration process. To address this problem, we have implemented an innovative solution: special burners integrated into the transport system, which reduce the moisture of the moving material.

The dust disposal route has been carefully designed using corrosion-resistant materials. The bag filtration system, the central point of the air purification process, benefits from an advanced cleaning technology with compressed air pulses.

A major challenge in these systems is the formation of acid condensation, which can damage the equipment. We addressed this issue through a double strategy: thermal insulation of filters and the use of advanced, acid-resistant filter materials.

The whole process is monitored and controlled through a smart system, aligned with the principles of Industry 4.0. This enables not only efficient local management but also the possibility of remote monitoring and intervention, thereby increasing operational flexibility.

With this holistic approach, we manage to significantly improve the efficiency of the sand preparation process, while reducing the environmental impact and ensuring a safer working environment for operators.
