Product Description
The main component of alumina ceramic balls is alumina, and the crystal structure is α-Al2O3. They are made through processes such as batching, grinding, powder making, molding, drying, and sintering. According to the different alumina content, they can be divided into medium aluminum balls, medium-high aluminum balls, and
high aluminum balls. They can also be called ceramic balls, porcelain balls, grinding balls, and wear-resistant porcelain balls. They are white spherical in appearance, with diameters ranging from 0.5mm-90mm. They use unique rolling molding and isostatic pressing technology to ensure their excellent wear resistance.
Features
1.High hardness: Alumina grinding balls have extremely high hardness and wear resistance, which can effectively maintain their shape and size, and improve grinding efficiency and precision. 2.
High density: The density of alumina grinding balls is much higher than that of ordinary grinding balls, which can provide greater grinding force and better grinding effect.
3.Good acid and alkali resistance: Alumina grinding balls have high chemical stability and are not easily eroded and corroded by chemicals such as acids and alkalis. They are suitable for grinding various granular materials of different properties.
4.No pollution: Since the material and processing process of alumina grinding balls are highly pure, they will not pollute materials and meet environmental protection requirements.
5.Long service life: Due to the high hardness and wear resistance of alumina grinding balls,their service life is longer than that of ordinary grinding balls, which can reduce grinding costs.
Applications
1.Ceramic industry: used for grinding, grinding, polishing and other processes in the manufacture of ceramic products.
2. Chemical industry: Alumina grinding balls can be used for grinding, mixing, dispersing and other processes in the preparation of chemical materials to obtain high-quality chemical materials.
3. Powder processing: In the preparation of ultrafine powders, nanomaterials, amorphous alloys and other fields, alumina grinding balls can be used as grinding and dispersing media for grinding, dispersing, mixing, reaction and other processes.
4.Environmental protection industry: The low wear characteristics and stable chemical properties of inert alumina grinding balls make them very suitable for use in environmental protection fields, such as wastewater and garbage treatment, which can effectively reduce and inhibit the generation of these wastes.
5.It can be used for grinding machinery and equipment such as ball mills, sand mills, magnetic bead mills, three-roll mills, dispersers, vibration mills, etc.
Grinding method of grinding balls
Dry grinding: Put the abrasive and additives directly into the grinder for grinding without adding any liquid.
Advantages: It solves the problem of grinding media contaminating raw materials. It is easy to operate and can be widely used in many different types of mills to grind most materials, improve production efficiency and reduce production costs. It does not produce wastewater, waste gas and pollutants, and is energy-saving and environmentally friendly.
Wet grinding: grinding after mixing abrasive and additives with water or other liquids.
Advantages: There is a lubrication state between the grinding balls and the grinding materials, which is not easy to generate heat energy loss and less wear; during the grinding process, the liquid can fill the gaps between the powders and maintain uniform dispersion;
Sampling in a short time will make the analysis process more reliable; It is easy to control the grinding load and grinding time.
Grinding machinery
It can be used for grinding machinery and equipment such as ball mills, sand mills, magnetic bead mills, three-roll mills, dispersers, vibration mills, etc.

FAQ
Q1:What are the factors that cause grinding ball wear?
A:1.Choice of ball hardness
2.Selection of grinding ball material
3.Temperature difference between solvent and air
4.Selection of particle size of grinding ball
Summary: The more the size of the grinding ball is the same, the more you can reduce the wear rate.
Q2:How to choose the right size of grinding balls?
A: The size of the grinding balls depends on the particle size of the grinding material and the required fineness. Usually small balls are used for fine grinding, while larger balls are used for coarse grinding.
Q3:What is the relationship between grinding ball diameter and grinding?
A: The larger the diameter, the greater the energy generated by the grinding balls when the ball mill is running, which can crush the materials quickly and grind them more coarsely. The smaller the diameter, the finer the grinding.
Q4:What is the delivery time?
A: If we have stock, the delivery time is within 5-7days after order confirmed. If there is no stock, it is usually 15- 20days.
Q5:What is the size in your products?
A: Our common size is 0.5mm-90mm. We can also produce according to your request.
