Why microcrystalline alumina ceramic balls are the best material for ceramic media？
Microcrystalline alumina ceramic ball is a widely used ceramic material. It is mainly made of alumina (Al2O3) corundum. The content of Al2O3 in high-purity alumina ceramics is above 99.9%, and the sintering temperature is as high as 1650-1990%. Ordinary alumina ceramic balls are mainly used to manufacture high-temperature, refractory furnace tubes and special wear-resistant materials, such as ceramic bearings, ceramic seals, water valve plates, etc.; 95 and 92 alumina ceramic balls are mainly used as ceramic abrasives and other corrosion-resistant materials. , wear-resistant department, etc.
The microcrystalline alumina ceramic ball mill has the following characteristics and is the best material for ceramic media. Its characteristics in operating equipment meet the following application technical requirements.
1. Microcrystalline alumina ceramic ball has high hardness: the Rockwell hardness of the steel is HRA 80-90, second only to the hardness of diamond, far exceeding the wear resistance of wear-resistant steel and stainless steel.
2. Microcrystalline alumina ceramic balls have excellent wear resistance: the wear resistance is 266 times higher than that of manganese steel and 171.5 times higher than that of high chromium cast iron. According to the customer's follow-up investigation, the service life of the grinding body can be extended at least 10 times under this condition.
3. Microcrystalline alumina ceramic balls are light in weight: their density is 3.6-3.8g/cm3, which is only half that of steel, which can greatly reduce the load on equipment.
Microcrystalline alumina ceramic ball is an advanced wear-resistant material. In recent years, with the continuous improvement of product quality in the entire industry, its products have experienced a rapid development process. The industrial scale ranges from small to large, and the product quality ranges from low to high. From the perspective of the application of alumina ceramics, its application scope is becoming wider and wider, and its consumption is also increasing. Especially the application of cement dry powder system and building ceramics in new dry production.
