Brief introduction of rolling ball process: the powder and water, adhesives, plasticizers, lubricants, etc., are added to the mud mixing machine to form mud by stale plastic mud material, into the mud extruder extrusion made of strips, and cut length and diameter of the mud section, and then into the ball rolling machine to make billet.
Ceramic balls are versatile materials with high hardness, wear resistance, and chemical inertness, making them indispensable in various industrial processes. They serve as efficient grinding media in ball mills, contributing to the fine grinding of materials in sectors such as mining, cement, and ceramics.
In the chemical industry, ceramic balls are crucial components in catalyst beds for processes like catalytic cracking and hydrocracking, owing to their resistance to corrosion and stability in harsh chemical environments.
Their high porosity and ability to withstand extreme conditions make ceramic balls ideal for gas and liquid filtration applications in industries ranging from petrochemicals to water treatment.
Moreover, ceramic balls are increasingly replacing steel balls in bearings due to their lower friction, higher hardness, and better wear resistance, leading to longer bearing life and improved performance, particularly in high-speed and high-temperature environments.
In valves and flow control systems, ceramic balls provide superior sealing properties and resistance to wear and corrosion, ensuring efficient operation in critical industries like oil and gas, chemical processing, and aerospace.
Additionally, ceramic balls play vital roles in medical devices, laboratory equipment, and electronics manufacturing, thanks to their biocompatibility, precision manufacturing capabilities, and electrical insulation properties.
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
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.
