FAQ：

1.What is the minimum ignition energy of a dust cloud?

1 mJ to 1000 mJ

MIE values usually range from 1 mJ to 1000 mJ. A lower value means the dust is more easily ignited – even a small spark could cause an explosion. Knowing the MIE of your dust is important for: Designing equipment that won't create ignition sources.

2.What is the minimum ignition energy test?

The MInimum Ignition Energy (MIE) test is conducted to determine the lowest spark energy that will ignite a powder when dispersed in air, as a dust cloud.

3.What is considered a low mie?

MIE typically range from 1 mJ to 1000 mJ [Janes]. The lower the MIE, the higher is the risk of explosion as a very small energy input can trigger a dust cloud explosion. MIE < 3 mJ should be processed with specific measures, the dust is extremely sensitive to ignition.

4.What is mie value?

The Minimum Ignition Energy (MIE) value is used to assess the likelihood of ignition during processing and handling. It helps to define explosion prevention methods. MIE < 100 mJ indicates a potential for ignition from static discharges from personnel.

5.How many microns is a combustible dust?

420 microns

In general terms, a combustible dust is a combustible solid particle having an effective diameter of 420 microns (μm) or smaller and is capable of being suspended in air.
