Powder explosion is extremely harmful to the flour processing industry. Powder dust refers to the powder suspended in the air due to dynamic action during processing. Powdered dust is a flammable substance. After being ground into small particles, the surface area increases. After reaching a certain concentration, it will produce a strong explosive force when it encounters an explosion source. Professional explosion-proof Industrial dust collector manufacturers PURE-AIR analyze the reason!

What is the cause of the dust explosion in the powder factory? Powder explosion generally meets three elements:

1. A powder with a certain concentration. The lower limit of the explosive concentration of ordinary flour dust is 9.7 grams per cubic meter. The second is sufficient oxygen, the dust and oxygen are mixed in a certain proportion, and the third is a source of supply. The minimum moisture content of the dust is related to the moisture and ash contained in the dust particles. (Larger water content can weaken or prevent dust explosion. The particle size of the adhesive dust will increase, which has the effect of additional incombustibles. The particle size is greater than 10 microns, and there is generally no risk of explosion. If the incombustible ash is divided into dust with larger ash content, the It can reduce the possibility of explosion. Since the dust explosion in an automobile parts grinding workshop in Kunshan on August 2 last year and the dust explosion accident in Taiwan's playground this year, the dust control work of my country's grinding mills has been highly valued by relevant departments, especially Industrial The dust purification management system has been continuously improved.

The current dust management measures for flour mills are mainly to adopt the reasonable design of spraying system equipment and factory building structure to reduce dust explosion accidents. It is generally not recommended for flour mills. Because this kind of equipment handles the dust, it will eventually explode if it is processed in the barrel. In order to prevent on-site explosions, an explosion-proof Industrial workshop dust collector is installed. You can also consult PURE-AIR Technology Co., Ltd. or the customer service center.
