Sustainable Mining and Metallurgy

The working principle of aluminum hydroxide slurry hydrocyclone was introduced, and the energy-saving technical transformation was carried out according to the actual production situation of alumina production line in an aluminum company, such as long service life, serious scarring, poor classification effect and large power consumption. After design and selection calculation, various parameters of the hydrocyclone were determined. A group of aluminum hydroxide slurry hydrocyclone with processing capacity of 600m³/h was selected to replace the original two groups, and the new hydrocyclone was reasonably optimized. The seed decomposition process was simplified by removing unnecessary power consumption equipment. After process optimization, the cost can be saved about 1.885 million yuan per year, and the efficient classification of aluminum hydroxide slurry can be realized.
