Other inflammable powders

Three conditions leading to dust explosions

1.Oxygen
2.Dust in concentration higher than the explosion lower limit threshold
3.Minimum ignition energy

Dust explosions occur when the 3 conditions of “oxygen”, “Dust concentration higher than explosion threshold”, and “minimum ignition energy” are all present. If even just 1 of these conditions can be eliminated then dust explosions can be prevented. So the crucial point in preventing explosions is eliminating oxygen or sources of sparks.

Dust Explosion Prevention and Protection

Electric motors, for instance, involve moving parts that can cause sparking. Dust explosion-proof motor is designed to prevent the invasion of the outside substances and is designed to eliminate risks of sparks.VNA-30SDN and VNA-45SDN have mounted the motor.

Aluminum fan casing, impeller, and producer have mounted on the VNA-SDN series. It prevents to have sparks generated by the fans.

Static electricity will make spark and could be ignition energy of dust explosion. Anti-electrostatic woven plate filter employs metal thread is woven into polyester technology and the filter has a strong and long time antistatic effect and reduces the possibility of generating spark cause by static electricity.

Countermeasures against the problem of a dust explosion caused by static electricity are indispensable. The antistatic coating Conductive paint is effective in preventing static electricity and noise by painting on metal and plastic. The conductive paint prevents the spark inside the dust collector and dust explosion.

Sealed electric control box is designed to structure that does not give triger of dust explosion.

Eath Bonding is used to reduce the risk of electric sparks by connecting bonding conductors between particular parts, it reduces the voltage there might have been.

In case of fire in the dust collector, the fire extinguishing port is designed to load Fire extinguishing agent in to dust collector.

Explosion isolation check valve is to safeguard the surrounding workers as well as machinery. Explosion isolation involves stopping an explosion energy through the duct to suction point. the aim of the check valve is to stop blast explosion power from traveling throug duct.

Explosion pressure diffusion port is designed to be the “weak” area of the dust collector body, an Explosion pressure diffusion port opens when predetermined pressures are reached inside the collector, allowing the excess pressure and flame front to exit to a Explosion pressure diffusion port. It is designed to minimize damage to the dust collector and prevent it from blowing up in the event of a deflagration, thereby reducing the safety hazard.
