AI Technical Summary
Traditional methods for classifying fly ash particles by size often rely on filters, which is inefficient.
A blowing device is used to classify fly ash. A fan blows the fly ash so that large particles fall into a large particle collection drawer, while small particles enter a small particle collection box through a pipe. A servo motor-driven vibration mechanism then causes the small particles to fall into the collection drawer. Combined with an arc-shaped metal mesh and a barrier mesh, precise classification is achieved.
It improves the classification efficiency of fly ash, ensures the effective separation of large and small particles, and reduces the need for manual operation.

[0002] Fly ash is the main solid waste discharged from coal-fired power plants. If a large amount of fly ash is not treated, it will produce dust and pollute the atmosphere. If it is discharged into the water system, it will cause river siltation, and the toxic chemicals in it will also cause harm to humans and organisms. The main product after coal combustion is fly ash. The main components of fly ash are aluminum oxide and silicon dioxide, and also include a variety of other components such as ferric oxide, titanium oxide, calcium oxide, sodium oxide and potassium oxide. Metallic aluminum has a wide range of applications in industry. It is necessary to reduce fly ash to obtain metallic aluminum.
