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.
They are primarily used as grinding media in ball mills and other grinding equipment, where they efficiently grind tough materials into fine powders. Additionally, ceramic balls are employed as filter media in filtration systems to remove impurities from liquids and gases, and they also serve as catalyst supports in chemical reactions.

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.
Wear small, high hardness, corrosion resistance, impact resistance, economic and practical.
(1) High wear resistance: the wear resistance of alumina grinding porcelain ball is better than that of ordinary porcelain ball. Can greatly extend the service life of the abrasive body.
(2) High purity: when the grinding porcelain ball is running, it will not produce pollution, so it can maintain high purity and improve the stability of the grinding effect.
(3) High density: high density, high hardness and high grinding, so as to save the grinding time and expand the space of grinding, can effectively improve the grinding effect.
(4) high strength, high temperature resistance (temperature resistance of about 1000ºC, 1000ºC or more for a long time is easy to stick), high pressure resistance, acid and alkali corrosion resistance (not in oxalic acid, sulfuric acid, hydrochloric acid, aqua Wang and other environments), thermal shock stability, stable chemical properties
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.
Located in Jinan City, Shandong Province, Jinan Junda Industrial Technology Co., Ltd. provides excellent wear resistance and impact resistance for mining and industrial applications, focusing on the development of wear-resistant alumina ceramics. With over a decade of experience and 200 highly skilled workers, we produce over 2000 tonnes of alumina ceramics and related products every month.
