Alumina is an ideal material for high-speed grinding and milling applications. It offers environmental benefits over metal-based grinding media that may cause issues.
High density
Alumina grinding ball are highly efficient media with excellent density, ideal for high-speed grinding and milling operations. Their wear resistance and cost efficiency make them popular choices in various grinding operations such as fine grinding or dispersing.
Cement industry uses it often, replacing steel balls in a ball mill with ceramic balls. This reduces costs associated with grinding and extends the equipment’s lifespan; additionally, it improves the quality of ground material.
Alumina ceramic grinding balls boast high hardness and resistance to corrosion, abrasion, and wear. Furthermore, these environmentally friendly balls do not pollute the environment.
They can be employed in a number of processes, such as grinding clays, glazes and blanks. Furthermore, they have found application in the mineral powder processing industry.
These alumina ceramic grinding balls are manufactured with top-tier materials and the latest molding technology. After being burnt in high-temperature tunnel kilns, these products boast excellent density and hardness.
Alumina ceramic grinding balls come in a range of shapes and sizes. Additionally, they are resistant to moisture so can be used in many different environments.
These alumina ceramic grinding balls are commonly used for wet grinding in the ceramic, cement, enamel and glass industries. Furthermore, they have become popular in both metal and non-metal dry powder grinding applications.
When selecting a grinding ball, several factors should be taken into account: the initial and final particle sizes being ground, its specific gravity, and hardness. Density plays an important role in determining the milling efficiency of the process.
It is essential to take into account the size of both grinding jars and balls when setting up your equipment. Matching these sizes ensures a smooth process runs throughout.
To guarantee a smooth grinding process and reduce contamination during grinding, the density of both the grinding jars and balls should be higher than that of the materials being ground.
High wear-resistance
Alumina grinding ball offers superior wear-resistance due to its high density and low abrasion. Furthermore, its impact resistance makes it ideal for the ball mill grinding process.
Therefore, material passing through a mill will be crushed more effectively and it helps reduce energy consumption of the machine. That is why selecting suitable ceramic grinding media for your application is so critical.
In general, ceramic grinding media come in several varieties such as alumina grinding ball, chrome steel balls and through-hardened carbon steel balls.
The alumina grinding ball is the most widely used type of ceramic media in ball mills due to its many advantageous characteristics. For instance, it boasts a low abrasion rate and can be utilized to grind various materials. Furthermore, its resistance to corrosion makes it suitable for numerous applications.
Another advantage of an alumina grinding ball is its low self-wear rate: 1.5/10,000. This extends the service life of the ball and lowers costs for customers.
Furthermore, alumina balls boast higher purity levels than their ceramic counterparts, meaning they won’t pollute the grinding materials. This could potentially improve the stability of the material being ground in the mill.
Ultra-low wear ceramic ball, boasting a self-wear rate of only 1.50/10,000, can extend the service life of the ball and is highly resistant to corrosion and rust, making it suitable for many applications.
Finally, alumina ceramic balls boast high density and hardness which can reduce the time required to crush material. This saves electricity and lowers production costs as well.
Alumina grinding ball have many applications, such as the production of glazes and blanks. They’re also commonly found in cement, paint and refractory industries. Furthermore, alumina grinding balls are part of the equipment used for processing metal and non-metal dry powders.
High temperature resistance
Alumina grinding ball are widely used in industries such as ceramics, steel&iron, glass, glaze and chemical processes. High-grade alumina grinding balls boast superior wear resistance, hardness and density that make them ideal for continuous grinding applications in ceramics, glaze making, pigment and glass industries.
High-grade alumina grinding balls are manufactured using advanced molding technology and calcined in high temperature tunnel kilns, offering exceptional durability, hardness, wear resistance and corrosion resistance. They’re perfect for processing abrasive glazes, blanks and mineral powders.
Alumina grinding ball boasts superior strength, hardness and toughness – capable of withstanding more than 1000 degrees Fahrenheit. It also exhibits excellent acid resistance, alkali resistance and corrosion resistance as well as thermal insulation effect which greatly extends service life of the grinding body. Alumina is widely used in ball mills, vibration mills, tank mills and other fine grinding equipment.
Furthermore, it makes an ideal abrasive material for lithium battery grinding due to its non-metallic composition that can withstand the high temperatures generated during the abrasive process.
alumina grinding ball is suitable for many grinding operations, such as dry and wet grinding, mineral and limestone grinding, iron ore grinding, cement grinding and more. Not only does this reduce milling time but it also enhances factory productivity significantly.
With a high specific gravity, material has an increased mass per volume, leading to more contacts per revolution and greater areas of attrition – leading to faster grinding or dispersion. Each contact increases the rate of grinding or dispersion significantly, often cutting milling time in half.
Moreover, the ball is highly stable at high temperatures and can reduce production costs. It finds application in chute liners, raw material grinding systems, ore crushing treatment system, coal-fired power plant pulverizing system and cement plant powder selection system. Furthermore, it serves as a wear-protection lining in the impeller of hard material conveying fans; this protects engine cylinders, piston crowns, rotors and other parts from abrasive impact thus prolonging engine service life.
