Production Process of White Corundum
The production process of white fused alumina mainly includes the steps of raw material selection, crushing, melting, crystallization, crushing and grading.
Raw material selection: The main raw material of White fused alumina is alumina ore. Generally, high-quality alumina ore is used as the main raw material, and it is carefully screened to ensure the purity and quality of the raw materials.
Crushing: Crushing the selected raw materials to obtain the appropriate particle size. The purpose of this step is to break down large pieces of ore into smaller particles for subsequent melting and crystallization processes.
Smelting: The crushed raw materials are melted at high temperature to form liquid alumina. In this process, impurities in the raw materials can be effectively removed by controlling the melting temperature and time.
Crystallization: The molten alumina liquid crystallizes under specific conditions to form White fused alumina with a stable crystal structure. This step is the key link in the production of White fused alumina and directly affects the quality and performance of the product.
Crushing and grading: After crystallization, the White fused alumina is crushed and graded to obtain products of different particle sizes and specifications to meet the needs of White fused alumina in different application fields.

The production and quality of white corundum depends largely on the particle size distribution, which directly affects its performance in different applications. In order to achieve the desired particle size and ensure uniformity, effective screening is essential.
Gyratory screen is an advanced screening machine designed to separate materials based on particle size. It uses a unique principle that combines horizontal and vertical motion to efficiently and precisely separate particles. The gyratory motion creates a gentle yet effective screening action, which is particularly beneficial for fine materials such as white fused alumina, preventing degradation while ensuring accurate classification.
There are several advantages to using a gyratory sifter to screen white corundum:
- High Efficiency: The gyratory sifter can process large amounts of material quickly, making it an ideal choice for industrial applications where time and efficiency are critical.
- Uniform particle size distribution: By effectively separating particles according to size, the gyratory screen ensures consistent product quality, which is critical to maintaining the performance of white corundum in a variety of applications.
- Gentle handling: The gentle sifting action minimizes the risk of damaging the fragile white fused alumina particles, thus maintaining their integrity and performance characteristics.
- Versatility: The gyratory screen can be easily adjusted to suit different mesh sizes and materials, making it suitable for a variety of screening requirements in white corundum production.
- Reduced Maintenance: Gyratory screens have fewer moving parts than traditional screening equipment and therefore typically require less maintenance, resulting in lower operating costs.
In conclusion, the use of gyratory screens in the white corundum screening process can improve product quality and operating efficiency. As the demand for high-quality abrasives continues to grow, the role of advanced screening technologies such as gyratory screens in white corundum production will become increasingly important.
