Ceramic Ball
What Is Ceramic Ball
Ceramic balls are divided into packing ceramic balls and grinding ceramic balls. Packing ceramic balls are widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries, as a support material for the catalyst in the reactor and tower packing. The main role is to increase the gas or liquid distribution point, support and protect the active catalyst with low strength. The inert ceramic ball has the characteristics of high temperature and high pressure resistance, low water absorption and stable chemical properties. Widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries, as a support material for the catalyst in the reactor and tower packing.

Ceramic balls can be divided into two types according to their use: filler porcelain balls and grinding porcelain balls. Filler porcelain balls, also known as inert alumina porcelain balls, are widely used in petroleum, chemical, fertilizer, natural gas, and environmental protection industries. As a cover support material for catalysts in reactors and tower fillers, the main role of packed porcelain balls is to increase the gas or liquid distribution points, and support and protect the active catalysts with low strength. According to the different alumina content of , the filler type porcelain balls are divided into common porcelain balls, inert alumina balls, medium alumina balls, high alumina balls, 99 high alumina balls, convex and concave grooved porcelain balls, active porcelain balls, open porcelain balls, , heat storage porcelain balls.
They are used in ball mills, jar mills, vibratory mills, and other fine grinding equipment. The grinding type porcelain balls have the advantages of high hardness, high bulk density, and corrosion resistance, and their crushing efficiency and wear resistance are much better than ordinary ball stones or natural pebbles and are widely used in ceramics, glass, enamel, pigment and chemical industries. According to the different alumina content, the grinding type porcelain ball is divided into silicon carbide grinding porcelain ball, microcrystalline medium aluminium grinding porcelain ball, and high aluminium grinding porcelain ball.

High alumina ceramic balls as grinding ball with high quality raw materials as well as the middle alumina ceramic balls are produced with the following technology: advanced spray drying technology, dry type full automatic isostatic pressure and high temperature roller kiln sintering technology.
Silicon Nitride Balls
Silicon nitride balls are a new material suitable for applications where high loads, high speeds and extreme temperatures are factors. Long life and the need for no lubrication makes this material very suitable for many applications. Silicon nitride is anti-magnetic and resistant to corrosion by most substances.
Zirconia balls

Factors to Consider When Choosing a Grade of Ceramic Ball
Application requirements
Determine the level of precision needed. High-precision applications like aerospace and medical devices often require grades g3 to g10. For general industrial applications, grades g25 to g50 may suffice.
Load and speed
Higher grades (g3, g5) are better suited for applications involving high loads and speeds due to their superior sphericity and surface finish.
Operating environment
Consider the environmental conditions, such as temperature, corrosion, and exposure to chemicals. Ceramic materials like silicon nitride (si₃n₄) and zirconia (zro₂) offer excellent resistance to harsh environments.
Cost vs. Performance
Higher-grade balls typically come at a higher cost. Balance the cost against the performance benefits to determine the most economical choice for your needs.
How to Make Ceramic Ball Smooth Surface Can Be
Why can ceramic balls be able to identify people with light? Many surfaces of ceramic balls are shiny, and some even light can identify people. What’s the secret here? In fact, the factors that determine whether there is light on the surface of ceramic balls are the flatness of the spherical surface; the more lubricated the spherical surface, the better the mirror effect; the rougher the spherical surface, the worse the mirror effect. The main factors that affect the flatness of the spherical surface are the internal structure of the material and the degree of processing outside the spherical surface. In the meantime, the outside processing of the spherical surface is relatively simple to understand. For example, the spherical surface of the grinding ball just after sintering is matt, and the spherical surface may have a mirror effect after polishing. The internal structure of the material includes pores, grain size, liquid phase, etc., and their effects on the flatness of the spherical surface are as follows:
Stoma
Because ceramic balls after sintering generally have a high density, and there are few pores caused by
sintering, the pores we are talking about here generally refer to major shortcomings caused by molding and other
reasons. For example, the powders for rolling balls include airflow powder, spray-dried powder, granulated
powder, etc. They are essentially fake particles composed of countless individual crystal grains. However,
because the powdering process is different and the particle strength of the powder is not the same, some false
particles may not be completely crushed in the application, resulting in the grains cannot be completely close
during the sintering process, resulting in shortcomings such as large holes.
Grain size
When the type of material is different, the degree of grinding of the material by each manufacturer is
different, and the formula and sintering process are different, it will lead to different grain sizes in the
sintered grinding ball. The finer the crystal grains, the flatter the spherical surface; the thicker the crystal
grains, the more uneven the spherical surface, just like paving a road with stones and sand. The zirconia
grinding ball crystal grains are mostly 0.3um-0.5um, and the alumina grinding ball crystal grains are mostly
1um-5um. The zirconia crystal grains are finer and the spherical flatness is higher, so the zirconia spherical
surface is brighter than the alumina spherical surface.
Liquid phase
Taking alumina ceramics as an example, in order to lower the sintering temperature of ceramics, some additives
are added in general production. Some of them are additives that can generate liquid phase in high alumina
porcelain, such as kaolin, bornite, silica fume, etc., which can form binary, ternary or more complex
low-melting eutectics together with other additives. After adding an appropriate amount of additives, on the one
hand, the sintering temperature of the ceramic can be lowered to make the crystal grains finer; on the other
hand, the liquid phase formed will be the same as the asphalt of the pavement, so that the spherical surface is
more flat and the spherical surface is naturally brighter.
Ceramic Ball Forming Method
Plastic extrusion
The plastic extrusion molding method is based on the size of the grinding ball, extruding the mud stick through a vacuum mud trainer, cutting the mud stick into corresponding size mud segments, using mechanical operation or manual methods to rub the small mud segments into balls, and After drying and drainage, raw embryos were obtained. This production technology has a small investment scale and simple equipment. It is mainly used for molding clay or subaluminum spherules. The spherules have a large particle size and poor sphericity.
Isostatic pressing method
Isosttic pressing is divided into wet isostatic pressing and dry isostatic pressing. In wet isostatic pressing, the powder is first filled in a soft mold with a spherical cavity. The soft mold is sealed and placed in the working cylinder of a cold isostatic press. The soft mold and powder are then passed through an ultrahigh pressure liquid medium. The material is uniformly compressed. After the pressure is released, the soft mold and the embryo body are taken out, and the spherical embryo body is obtained by demolding outside the working cylinder. This molding method does not require high powder, and the embryo body has a high density and uniformity.
Roll forming method
The roll forming method is a semi-dry and wet forming method that draws on the production process of Chinese medicine pills or forming dumplings. It wets the core by spraying liquid, and the dry powder added on the outside of the wet core is rolled and dense Three-step cycle forming. The molding process equipment is simple, can realize automatic operation, and has a high efficiency in producing small-diameter porcelain balls.
