Effect of Dust on Quality of Brown Fused Aluminium Oxide

When Brown Fused Aluminium Oxide is used as abrasives for sandblasting, the effect of dust on it is the size of the area.
When used for making grinding wheels, dust has an effect on the adhesive. It may cause loose adhesive.

2. Cleaning Methods

1) The bag is used in textile or textile filter cloth made of felt bag, filter fabric using fiber filter dust containing gas. When the dust laden gas into the bag filter, particles larger proportion of dust, due to gravity sedimentation down, falling into the ash bucket, smaller dust containing gas through the filter, the dust were delayed to purify the gas. It can also use “cyclone + bag dust filter” the scheme selection method of “cyclone + bag dust filter” combination of dust can remove large particles, fine dust and remove 10 m, dust emissions can reach the national standard of environmental protection.

2) Bio nano membrane dust suppression technology, also known as bio nano dust suppression technology, is a new type of industrial dust control technology is better than that of a traditional dust bag, dust and other closed water, has been used in different overseas. In recent years, the technology has been gradually applied in many provinces and cities in china. Bio nano membrane dust suppression technology is produced in the source of dust suppression, through biological nano membrane dust machine, generating accurate ratio of bio nano membrane, spray attached to the material, through the adsorption of biological nano membrane, small particles of dust will reunite into large particles, the weight increase and not drift in the air of dust. Biological nano film dust suppression technology can effectively control the organized and unorganized dust, dust removal rate can be more than 95%, the effect is stable. Biological nano film preparation does not affect the quality of the finished product and has no second pollution to the environment. In addition, biological membrane dust suppression technology can effectively prevent PM2.5, PM10 fine particulate pollution.

3) Spray dust removal is a traditional wet dust removal technology. The traditional spray dust removal is the medium which uses the mist as the dust removal, and the mist is formed by the traditional spray nozzle, and the material is wrapped to achieve the effect of dust removal. Spray dust is widely used in mines, quarries, steel mills and other industrial fields, there is effect on removing dust, but the disadvantages of this technique is the wet material, affect the quality of the finished product, and the wet sticky material, the production equipment will cause greater wear and tear, it can also produce the water pollution, and it need to settle the sewage treatment.

The dust removal on the surface of the spray is more effective and less cost, but the cost of the comprehensive utilization and management, as well as the damage to the environment, is very high. In recent years, the traditional spray dust removal technology has gradually been replaced by cloud dust suppression technology.

4) Clouds of dust suppression technology by high pressure ion atomization and ultrasonic atomization technology, ultra-fine mist generated 1 m~100 mu m; ultrafine particle cloud fine, can fully increase the contact area and dust particles. Cloud particles and dust particle collision and coagulation, form agglomerates, agglomerate become more heavy, until finally the natural sedimentation, to eliminate the dust cloud cloud of dust particles; suppression technology, 30%~40% particle size below 2.5 m, the control effect of atmospheric fine particle pollution is obvious. The cloud of fine particles, adsorption of dust, a substantial increase in the efficiency of dust removal, and not wet materials, it avoids the drawbacks of traditional spray technology.
