Introduction of Aluminium Oxide
Alumina powder is white, odourless and tasteless, with reliable organic chemistry, high purity and good dielectric strength properties. It is also known as bauxite (the main component of which is alumina) in mining, ceramics and material science. With the rapid development of electrolytic aluminium, ceramics, medicine, electronics, machinery and other industries, the market demand for alumina still has a large space for growth, alumina production will continue to grow. In addition to the industries mentioned above, alumina is also widely used in different fields such as aerospace industry, automotive industry, semiconductor industry, etc. The large demand for alumina has brought a lot of alumina trading to the international market, so how to safely and securely and properly store and transport alumina powder has become a concern for many alumina powder producers and buyers.
1. Aluminium oxide powder should be stored in a cool, sealed, dry and well-ventilated warehouse.
2. The storage place should be far away from fire and heat source, and have suitable materials to shelter the leakage.
3. It should be stored separately from the oxidant and should not be mixed.
4. Packing should be complete and loading should be stable.
5. Ensure that there is no leakage, collapse, fall or damage during transport.
6. It should be protected from exposure to sun and rain during storage and transport.
The storage of alumina powder needs to be sealed, dry, well ventilated, etc., to ensure that the storage equipment does not leak and is not damaged when loading and unloading, the traditional bag storage does not meet the above conditions and may bring about environmental pollution, however, the steel plate silo (welded steel plate silo and spiral crimped steel plate silo) can achieve the safe storage of alumina powder and has been widely used. Dazheng alumina silo system includes steel plate silo and supporting auxiliary equipment, which is designed and processed for alumina storage and transportation, and is widely used in alumina plant, aluminium ingot plant, refractory material plant, ceramic frit plant and so on.
1. Low initial investment: due to the adoption of a number of Dazheng patented technology, it can save about 50% of building materials and more than 60% of land.
2. Short construction period: Dazheng's welded steel plate silo and spiral coiling silo have a short construction period, which can help customers put them into use quickly and recover the capital.
3. Good airtightness: Dazheng steel plate silo adopts the patented vacuum sealing technology, and the quality of alumina is basically unchanged by the physical indexes when it is stored in the silo for several months.
4. Long service life: under standard maintenance, the service life of
Steel Silo can reach 30-50 years.
5. Energy-saving and environmental protection: the alumina feeding and discharging process adopts the patented dust removal technology, which will not cause pollution to the surrounding environment.
6. Light weight: the low self-weight of the steel silo greatly reduces the load and cost of the infrastructure.
Points to note when using steel plate silos to store aluminium oxide powder
1. Compared with traditional storage materials, alumina has better fluidity, so the hoop force at the bottom of the steel plate silo is relatively large, and the rigidity of the steel plate is required to be higher.
2. In order to avoid the effect of alumina segregation on the electrolysis tank during alumina conveying and storage, the top of the alumina silo should be equipped with a silo top distribution device, so as to reduce the segregation effect caused by the natural accumulation of alumina.
3. When the alumina powder is stored in the silo before it is used for smelting, the level of the silo must be monitored to ensure that the alumina powder is kept in the best condition.
4. When alumina is stored for a long period of time, some of the alumina is retained at the bottom of the silo, leading to slagging and causing clogging. We have rich experience in the design and operation of alumina silos to ensure that the unloading rate of the alumina silo is more than 95% and that the alumina is discharged smoothly.
