Explosion Safety for mixers

Whether a mixer has to be protected against explosions depends on the different properties of the respective mixer.

These include 

  • The speed of the stirrer
  • The possibilities to completely eliminate ignition sources, e.g. mechanical sparks, electronic charges, hot surfaces, glowing embers


In addition to the safety-relevant key data of the dust, the links to other parts of the system and the type of connection are important factors for the design of mixers. The type of filling also plays a role. Through this, for example, the vent area is reduced in accordance with EN 14491 during pneumatic filling.

The overall picture counts:

The protection of individual system components is only as good as the protection of the entire system. Pay particular attention to having sufficient decoupling devices, and the protection against “over engineering”. Only if the entire system is observed, and the individual protective measures are aligned to each other, will your Explosion Safety concept be safe AND economic.

We therefore offer you comprehensive protection concepts and on-site consulting, on how you can implement organizational measures to achieve a greater degree of safety.
