How pharmaceutical manufacturer could fulfill Atex in grinding processes

Atex design Makes it Possible

There are many technical process solutions behind the Atex concept to convey, finely mill or disagglomerate, as well as dose and fill various products. The milling chamber and the milling head area were in Atex 3D (Zone 22).

The rest of the equipment is installed outside the defined Atex zone, bringing the customer the advantage of safely manufacturing the product with a safe, cost effective solution. Having installed the rest of the system outside the Atex zone ensured greater safety and enhanced affordability.


Summary: The customer was completely satisfied with the execution of the entire project: planning, engineering, installation and operation. The system operators were satisfied with the overview of the process monitoring, due to its simple and safe operation.

Despite the difficult properties of saccharose when milling (such as sticky, smearing, heat-sensitive), the hammer mill runs without blockage and provides high, trouble-free throughput of dry product. The safety gains clearly more than paid for themselves for the customer, and for Frewitt, a satisfied customer.
