Main ingredients and preparation principle of alumina ball.What do we need to make alumina balls? Do you know the main ingredients and preparation principles needed for alumina balls.
1. What is needed for alumina ball production
We know that the main component of alumina balls is alumina, and a rough process is to form alumina powder one by one and calcinate one by one. From the perspective of the process, the production of alumina balls involves raw materials, processes, and equipment. First of all, we need equipment. Then what equipment is needed to make alumina balls. We purchase raw materials here, and do not count the equipment for making raw materials.
2. Equipment needed for alumina ball production
The equipment required for the production of alumina balls includes static isostatic press, ball rolling machine, tunnel kiln, etc. It mainly produces corundum grinding balls, high alumina balls, alumina balls, heat storage balls, refractory balls, porcelain balls and other products. It has 3 large ball mills, 6 small ball mills, rotary kilns, tunnel kilns, and inverted flame kilns. The high-quality alumina powder and the alumina ball made by isostatic pressing grinder have high density.
3. Materials and processes required for the production of alumina balls
The aluminum hydroxide produced by the Bayer process is then ground and finely processed into balls. The balls are sintered at a high temperature in a kiln to make activated alumina balls or other types of activated alumina series products. We purchase raw materials for production according to the user’s indicators. The purchased raw materials are first screened, processed into powder, etc., then enter the silo, and then made into ball billets, which are calcined in a tunnel kiln.
4. Molding method for making alumina balls
At present, the main forming methods are dry pressing, isostatic pressing, and roll forming; dry pressing has simple operation and low investment. Because of uneven pressure, the internal distribution of the blank is uneven, which affects the comprehensive performance of the grinding media. The isostatically pressed body has the characteristics of high strength, high density and uniform internal. Rolled balls have the characteristics of production equipment, raw materials, simple operation, good sphericity, easy sintering, and low preparation cost.
