Dust explosion protection measures are essential for industrial companies today. We have contributed to making grinding systems safer today thanks to many years of research and further development of safety systems. All our hammer mills and all other machines are tested to be resistant to explosion pressure shock and flame penetration, up to an explosion overpressure of at least 0.4 bar. Our machines and the safety technology used comply with the necessary national and international specifications.
The pressure-shock-resistant design of appliances and machinery, the optimum design of pressure relief devices and the use of explosion decoupling of the supply and discharge channels play a decisive role in ensuring a safe system. Safety always originates in the system. Our concepts for system safety as well as the comprehensive documentation will assist you in communicating with the responsible authorities or experts. Regular inspections and the maintenance of your safety equipment allow us to guarantee the permanent functional safety of your plant.
We work together with renowned testing institutes (Notified Bodies) at home and abroad. This is where the machines and appliances we use, some of which we have developed ourselves, are tested for their safety and effectiveness under actual operating conditions.
We offer comprehensive advice and draw up explosion protection concepts that are individually adapted to your requirements. In doing so, we use different explosion protection systems from various manufacturers. Our objective is to create the optimum explosion protection concept for each customer.

In the case of a dust explosion within the grinding system, it is vital to discharge the resulting explosion overpressure (pmax e.g. 9 barg) in a controlled manner and consequently reduce it to a harmless level (pred=0.4 barg). When doing so, no flame may escape from the machines and appliances in an uncontrolled manner.
Structural dust explosion protection only works reliably if the components are professionally coordinated to work together with one another.
1. Explosion decoupling of the feed and discharge channels:
2. Pressure-shock resistant machines and system parts between the decoupling points.
3. Explosion decoupling of the supply and exhaust air:
4. Flameless explosion venting at the mill secondary container and at the filter system
5. Active explosion suppression by means of extinguishing bottles
