Alumina Grinding Ball (Wet Grinding) Descriptions

Alumina Grinding Ball (Wet Grinding) is an inert ball with no voids inside and has good wear resistance, corrosion resistance and high temperature resistance. These Alumina ceramic grinding balls made of top-notch materials with the latest molding technology. Later, they're burnt in high temperature tunnel kilns. The result is an alumina product with high-density and high hardness that's also resistant to corrosion and wear. The main component of alumina grinding ball is alpha alumina, which is divided into high alumina ball and medium alumina ball according to the content of Al2O3.

Alumina Grinding Ball (Wet Grinding) Features

Alumina grinding balls for ball mills (Al2O3) have lower abrasion, high hardness, and impact resistance amongst their main characteristics. But they're also cost-effective as they increase grinding efficiency by 40-60% (which lets you save energy and money); and eco-friendly, as they do not contaminate the environment. The durability of the Alumina Ceramic balls is remarkable as well: they are 20 to 40 times more resistant to wear in comparison with natural and common balls.

-Low abrasion

-High hardness and density

-Impact resistance

-Energy Efficient

-Environment friendly

-Corrosion resistance

Alumina Grinding Ball (Wet Grinding) Applications

The alumina ceramic balls stabilize the chemical composition of the material being grind. Alumina grinding balls are mainly used as grinding media. It has great seismic stability and it's ideal for grinding glaze and blank. It's also perfect for mineral powder processing, for which it's widely used in the inorganic mineral powder industry. Additionally, it can be found in the cement, paint, and many refractory materials industries, as part of the equipment for metal and non-metal dry powder grinding. High alumina ceramic grinding ball is a neutral material, a solid insoluble in water, and is often used as a wear-resistant abrasive material.
