Dust explosions often originate from inside dust collectors, mixers and other dust-related containers. Once an explosion occurs, it will cause serious damage to the container structure and the environment around the container. Explosion relief technology releases the explosion energy to the external area of ​​the powder-related container by setting a bursting disc that ruptures at a specified pressure, weakening the explosion pressure and flame inside the container, and preventing the container from being structurally damaged in the explosion. In order to prevent damage, a flameless explosion relief device is required.
