White corundum is the most suitable raw material for obtaining alumina powder, but the first step is to destroy it to a certain extent through a drum destroyer. Considering that there are many impurities in the raw materials, pickling and water washing are needed after destruction to effectively remove the impurities.
Even if it is so obtained, only alumina particles are obtained, and there is still a step away from alumina powder, that is, grinding. Since the material after washing is still wet, it must be dried in a drying equipment if it is to be ground, and then it can be ground to the desired particle size. Although this is already alumina grinding micropowder, it must be calcined, soaked and other subsequent treatments to achieve the desired performance.
