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. 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.
Size Selection of Ceramic Ball
The size of the ceramic ball should be selected according to the size of the catalyst. Generally, it follows the 2X rule (or gradation), that is, the diameter of the ceramic ball should be twice the diameter of its adjacent catalyst so that the distribution of materials is the most uniform and the pressure drop It is also the smallest and the reactor is optimized.
In a fixed-bed reactor, a certain height of inert ceramic balls or fillers is usually added above and below the catalyst.
Usually, two layers are laid. The layer next to the catalyst is covered with 1~3mm porcelain balls, the outer layer is covered with 4~6mm porcelain balls, and the wire mesh is laid on the outermost layer. The wire mesh is mainly used for gas distribution, filtering small particles of catalyst entrained by gas or filtering impurities entering the bed. It also plays a role in preventing the falling of the bed and supporting the bed. Generally, each size of the ceramic ball is 100mm thick. Did not notice that there are regulations in that standard. Even very fine catalyst particles cannot be filtered by this method, and other methods need to be taken to filter the catalyst that may be carried out.
What Are The Differences Betwee Ceramic Ball And Alumina Grinding Ceramic Ball
The Catalyst bed support ceramic ball and the grinding ceramic balls are both ceramic balls. The Catalyst bed support ceramic ball are used for making ceramic balls. The grinding ceramic balls are mainly used for grinding. The raw materials of the two are the same. They are two different uses of the same product. So what is the difference between them?
The key function of the filler ceramic ball is to add gas or liquid. The strength and protection of the catalyst support are not high. According to the content of alumina in the inert alumina Catalyst bed support inert ceramic ball, ceramic balls can be divided into ordinary ceramic balls, inert alumina ceramic balls, medium alumina ceramic balls, high alumina ceramic balls, 99 high alumina ceramic balls, and solid grooves. Ceramic balls, active ceramic balls, porous ceramic balls and microporous ceramic balls, etc.
The grinding of grinding ceramic balls is a kind of precision grinding equipment, such as ball mills, vibration grinders, etc. The grinding hardness, bulk density, corrosion resistance, wear resistance and grinding efficiency of ceramic balls are higher than ordinary stone or natural stone. . Commonly used in ceramics, glass, enamel, paint, chemical and other industries. According to the different alumina content, ceramic grinding balls can be divided into silicon carbide grinding balls, ceramic grinding balls, and microcrystalline grinding aluminum.
First, the sizes of the two are different.
The alumina filler ceramic ball is smaller, usually 10-30 mm in diameter, and the most commonly used is 25 mm. The grinding ceramic balls usually use 50 mm or more.
Secondly, the content of alumina is different between the two.
Ordinary Catalyst bed support inert ceramic ball have low alumina content. In the range of 25% to 70%, due to various requirements such as hardness, grinding ceramic balls requires a higher aluminum content. Usually used for 95% alumina content.
How Ceramic Balls Are Made
Regardless of the ceramic material used, the manufacture of ceramic balls begins with the selection of some high-purity ceramic powders, such as aluminum oxide, zirconium oxide, or silicon nitride. These powders are then mixed with a binder to improve the formability of the mixture. This mixture is then formed into spherical shapes using methods such as isostatic pressing, which uses pressure in all directions to ensure uniform density and shape, or through granulation and sintering techniques.
After forming, the balls are sintered in a high-temperature furnace to achieve the required mechanical properties, such as hardness and toughness. The sintering temperature and atmosphere depend on the type of ceramic; for example, silicon nitride requires nitrogen to prevent oxidation and increase strength. After sintering, the balls undergo a precise grinding and polishing process to achieve the desired size and surface smoothness.
The differences in the manufacturing process for different types of ceramic balls mainly involve the selection of raw materials, sintering temperature, and atmosphere. For example, zirconium oxide balls may be stabilized with yttrium oxide to enhance their thermal properties, while silicon carbide balls are sintered at higher temperatures to maximize their hardness and wear resistance. Each step is carefully controlled to ensure that the balls meet the specific performance criteria required for their intended industrial use.
Ceramic Balls Vs. Steel Balls
Ceramic balls and steel balls are utilized across various industrial applications, each having distinct advantages and performance characteristics.
Hardness and Wear Resistance
Ceramic Balls: Typically harder than steel balls, leading to better wear resistance and less deformation under load.
Steel Balls: Softer compared to ceramic balls, which can lead to quicker wear and shape deformation under high loads and speeds.
Corrosion Resistance
Ceramic Balls: Highly resistant to corrosion and chemical attacks, making them suitable for harsh environments such as acidic or alkaline conditions.
Steel Balls: Prone to corrosion unless specially treated or made from stainless steel, which can increase costs.
Weight
Ceramic balls: Much lighter than steel balls, reducing bearing loads and improving efficiency in applications requiring high speeds.
Steel balls: Heavier, causing increased wear and energy consumption in high-speed applications.
Thermal Properties
Ceramic Balls: Excellent stability in high-temperature environments, maintaining their strength and hardness.
Steel Balls: Tend to lose hardness and dimensional stability at high temperatures.
Ceramic balls are widely used in the industrial field because of their high hardness, high strength and low wear. The alumina ground down is a neutral material and will not pollute the final raw materials. There will be a certain probability of inappropriateness or problems in the actual use process. Sometimes it is a product quality problem, sometimes it is a selection problem, and there are also damage to the product itself caused by changes in working conditions.
Black spots on the surface of the ceramic ball: Ceramic balls have pipelines to transport materials during the preparation process, and there will be iron removal processes in the later stage. Some balls will have black spots. For example, the pharmaceutical industry has strict requirements on impurities in the final product and will have secondary selection.
Excessive wear and breakage during ceramic and use: First, whether the alumina ceramic ball meets the national standard strength, density and wear. First check whether it is a product quality problem, and then look at the selection. The ball mill generally selects one to four models according to the size and feed and discharge particle size. The difference between the models is generally added in sequence. If the jump increase will lead to a large difference between the ceramic balls, and there will be a phenomenon of large balls hitting small balls between the two ceramic balls. There is no ceramic material and the self-wear is too large.
The dry grinding environment has more technical requirements for grinding balls than the wet grinding environment, so the quality stability of ceramic grinding balls must be good, each production process must be standardized to reduce human factors, the process inspection must be strict and in place, and each step of processing must be standardized, so as to ensure the use of the final product.
