White Ceramic Balls for Chemical Industry Use

Product Description

Company Profile

SiC ceramic balls

Ceramic bearings are often extremely resistant to corrosion and require very little lubrication in systems such as automotive
engines and gears. They also typically have very high temperature resistance and can handle acidic and alkaline environments.

Compared with steel, its mass is lighter than steel, its friction coefficient is smaller, its motion performance is better, its elastic modulus is 50% larger than that of steel, its thermal expansion coefficient is smaller than 25% of that of steel, it can maintain high strength and hardness before 1000℃ under high temperature, and it is resistant to corrosion. No rust, non-magnetic, can work without oil
lubrication.

Performance	1. High strength and high toughness, no broken beads under high-speed impact. 2. Good sphericity and smooth surface. 3. Ultra-low wear, wear resistance is 30-50 times that of glass beads, 5 times that of zirconium silicate beads, and 6-8 times that of alumina beads. 4. High density and high grinding efficiency.	1.59% lighter than steel balls, which means less centrifugal force and wears less grooves at high speeds and accelerations 2. The elastic modulus is 44% larger, which means less deformation under load. 3. Smaller friction coefficient. 4. The linear expansion coefficient of silicon nitride ceramic ball is 3.2×10-6/K, which is almost 1/4 of bearing steel, and can endure high temperature. 5.Excellent surface finish can be achieved, Ra can be 4~6. 6. Can endure high temperature, high hardness and strength up to 1050 ℃.	Silicon carbide ceramic balls have stable performance, and silicon nitride has good overall performance. Compared with steel, its mass is lighter than steel, its friction coefficient is smaller, its motion performance is better, its elastic modulus is 50% larger than that of steel, its thermal expansion coefficient is smaller than 25% of that of steel, it can maintain high strength and hardness before 1000℃ under high temperature, and it is resistant to corrosion. No rust, non-magnetic, can work without oil lubrication.	1. High wear-resisting: The alumina balls wear resisting is higher than the common ceramic balls. When it is working, the ball will not pollute the grinded materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze. 2. High density: the high density, high hardness and the high grinding Characters save the grinding time, enlarge the smashing room. So It can improve the grinding efficiency.
