low alumina ball is a kind of inert alumina porcelain ball made of a material with relatively low alumina content.

I. Characteristics

2. Corrosion resistance: It has good chemical corrosion resistance, and can resist the erosion of corrosive media such as acid and alkali to a certain extent.

2. High strength: Although the alumina content is low, it can still maintain high strength and hardness, and can withstand certain pressure and wear in different industrial environments.

3. Good wear resistance: It can maintain good performance in the environment of friction and wear and prolong the service life.

4. Low specific gravity: Compared with high alumina balls, the specific gravity of low alumina balls is relatively low, which has advantages in some application scenarios where weight is required.

Choosing a low alumina ball that suits your needs needs to be considered from the following aspects:

1.** Clear application scenario ** : - ** Ceramic industry ** : If used in the ball milling process of ceramic production, it is necessary to select low alumina balls with moderate hardness and good wear resistance to ensure that they will not be broken or excessive wear during the long-term grinding process, affecting the grinding effect and quality of ceramic raw materials. For example, in the production of domestic ceramics, the hardness and wear resistance of low alumina balls are required to be higher in order to grind the ceramic raw materials more finely and evenly.

2.** Chemical industry ** : When used as packing material for chemical reaction towers, the chemical stability and thermal stability of low alumina balls are crucial. It is necessary to select low alumina balls that can remain stable under chemical reaction conditions, do not react with reactants or catalysts, and can withstand certain temperature changes.

3.** Attention to alumina content ** : Different application scenarios have different requirements for alumina oxide content of low alumina balls. In general, the alumina content of low alumina balls is more common at about 17%-23%. If the high temperature resistance of the material is required, you can choose a low alumina ball with a slightly higher alumina content; If the requirements for corrosion resistance are high, you may need to choose products with lower alumina content. At the same time, pay attention to the alumina content test report provided by the supplier to ensure that the alumina content of the product meets its own needs.

4.** Inspection of physical properties ** : - ** Hardness ** : hardness is one of the important indicators to measure the quality of low alumina balls. low alumina balls with higher hardness are better able to resist wear and impact, but hard low alumina balls can cause damage to grinding equipment. Therefore, according to the specific application scenarios and equipment conditions, choose the appropriate hardness of low alumina balls.

5.. ** Understand chemical properties ** : - ** Corrosion resistance ** : If used in a corrosive environment, low alumina balls with good corrosion resistance should be selected. You can learn about the corrosion resistance of the product by looking at its chemical composition and corrosion resistance test reports. -6 ** Thermal stability ** : For low alumina balls used in high temperature environments, thermal stability is key. To choose products that can maintain structure and performance stability at high temperatures to avoid deformation, rupture and other problems at high temperatures. 5. ** Evaluation of suppliers ** : 7 ** Production qualification and reputation ** : The selection of suppliers with good production qualification and reputation can ensure product quality and after-sales service. You can view the supplier's qualification certificate, production license and other relevant documents to understand its production capacity and quality management system.

low alumina balls need to pay attention to the following aspects during use:

1.** Use environment ** : - ** Temperature control ** : Understand the use of low alumina ball temperature range, to ensure that the temperature of the use environment is within its withstand range. If the temperature is too high, it may cause the structure of the low alumina ball to change, the strength to reduce, and even break and other problems; If the temperature is too low, it may affect its performance.

2.- ** Avoid contact with highly corrosive substances ** : Although the low alumina ball has a certain corrosion resistance, it may still cause damage to it if it is exposed to highly corrosive substances for a long time. In the process of use, it is necessary to avoid direct contact between low alumina balls and strong corrosive substances such as strong acids and alkali.
