Alumina Ceramic Dry Grinding Media for Cement Grinding


Five major advantages of using alumina ceramic dry grinding media instead of high-chromium steel balls for cement grinding:
- Energy and Consumption Reduction: The loading capacity is 60% of that of steel balls, reducing the mill main unit current by over 20%. This results in over 15% electricity savings per ton of cement produced.
- Quality Improvement: Improved grinding efficiency, improved cement properties, and more optimal particle size distribution. Improved particle sphericity improves cement’s adaptability to concrete admixtures.
- Cooling and Noise Reduction: The mill internal temperature is reduced by over 20°C, reducing mill noise.
- Wear Resistance: The ball consumption of microcrystalline, high-strength, and wear-resistant ceramic grinding media is 50% of that of steel balls.
- Environmental Protection: Using microcrystalline, high-strength, and wear-resistant ceramic grinding media contributes to green production.

Alumina Liner
Microcrystalline wear-resistant alumina liner is a special wear-resistant ceramic formed by dry pressing and high-temperature sintering. Its Rockwell hardness is HRA80-90, second only to diamond. It offers excellent wear resistance, impact resistance, and ease of installation. Its theoretical wear resistance is 260 times that of manganese steel and 170 times that of chromium steel. It is widely used on the interior and exterior surfaces of material conveying and powder selection equipment in the steel, power, coal, cement, and other industries, effectively extending equipment life. We can manufacture various specifications to meet customer requirements.
