Junda ceramic ball refers to alumina powder as raw material, after ingredients, grinding, powder (pulping, mud), forming, drying, firing and other processes produced, mainly as grinding medium and widely used ball stone. Because the content of alumina is more than 92%, it is also called high aluminum ball. Appearance is white ball, diameter of 0.5-120mm.

1. Selection and preparation of raw materials: The first step in the production of ceramic balls is to choose the right raw materials. Commonly used materials are alumina, zirconia and other ceramic materials. These raw materials go through various processing steps to ensure they have the required particle size and purity.
2. Mixing and deployment: After the raw materials are pre-treated, they are fully mixed and deployed to achieve uniform composition.
3. Molding: There are several methods of molding ceramic balls, including extrusion, isostatic pressure and injection molding. The choice of method depends on factors such as the type of material used, the size and shape of the ball required, and the yield.
4. Drying: Once formed, the billet (unfinished ceramic sheet) is dried to remove moisture from it. Drying is usually carried out in a controlled environment to prevent cracking or deformation of the body.
5. Sintering: After drying, the billet is sintered, which is a process of heating to high temperatures in a controlled atmosphere. Sintering binds particles together to form a dense, hard ceramic material.
6. Processing and finishing: After sintering, the ceramic ball may require further processing or finishing to achieve the desired surface finish.
7. Quality control: Throughout the production process, quality control measures are in place to ensure that the ceramic ball meets the required standards
Grinding, polishing, etc
It is widely used in the precision processing and deep processing of all kinds of ceramics, enamel, glass and thick and hard materials in chemical plants, as the grinding medium of ball mill, tank mill, vibration mill and other fine mills.
The company chooses mountain aluminum alumina as the basic raw material, with high purity, less impurities and stable quality. Implement Kanban production, the whole production process can be controlled and traceable. Each batch of products are selected for strict inspection, process and result testing to ensure the stability of the finished product performance, excellent quality. Ensure alumina content, ensure low wear, adequate supply, timely and convenient delivery.
