Metal parts must be made by grinding, and a lot of metal dust is caused during the grinding process. The increase of metal dust in machinery and equipment not only harms product quality, but also seriously harms the respiratory tract of employees. There is a safety risk of dust explosion. It is very necessary to be equipped with an Explosion-proof dust collector.

In addition, a certain total amount of metal or metal and non-metal mixed dust will be generated during the production process. When the dust concentration in the air reaches the explosive limit, it will easily cause an explosion when it encounters an ignition source. Especially aluminum, magnesium dust and mixed dust with aluminum, magnesium and other non-ferrous metal components, the explosion damage is higher.

Metal dust is highly sensitive to fire.

The minimum sparking capacity of most metal powders is less than 10 ml. For extremely fine metal powder, the minimum sparking capacity is less than 1ml, and it has strong sparking sensitivity. According to investigations, high-temperature surface, impact, friction, and electrostatic induction flames are common sources of ignition for dust explosions.

Metal dust, which is highly sensitive to fire accidents, is very easy to catch fire and cause dust explosions under the effect of static induction flames and other open flames.

Serious harm after a safety accident occurs.

Compared with flammable gas, the specific energy of combustible dust cloud is higher, and the specific energy of metal particles in combustible dust is higher. When metal dust consumes 1ml of CO2, the heat released is generally 3 times that of dust, as shown below:

Therefore, metal dust is generally used as fuel methanol for rocket propellants and other airline aerospace industries. High-efficiency, energy-relative-density, metal dust, after a fire accident, explodes, and an instantaneous explosion will cause a great explosion. The working pressure and the rate of increase in pressure will cause more serious safety accidents.
