Natural pebble stone, alumina balls, zirconia balls are common grinding media in market. Choosing the correct grinding media is the key to improve grinding efficiency, reduce the overall cost and improve the product quality.


Natural grinding media mainly refers to the naturally formed materials such as silica, sea pebbles, cobbles, etc.These are the earliest medium used in ceramic industry (SiO2 as the main component), with dense texture, good impact resistance, stable abrasion & low price.


Alumina balls is a kind of high-quality grinding media, also known as alumina ceramic balls, according to alumina content, can be divided into 92%/95%/80%/75%/68% alumina balls. Widely used in grinding raw materials such as white cement, mineral processing, ceramic, electronic materials, magnetic materials, coatings and paints, because of its excellent properties (wear resistance, corrosion resistance, high temperature resistance and impact resistance). 


ZrO2 grinding media ball refers to ZrO 2 ceramic ball with stabilizer and ZrO 2 content above 90%. Compared with Al2O3 ceramic ball, ZrO 2 ceramic ball has higher wear resistance and grinding efficiency.
Due to its excellent high hardness, high strength, high toughness, high wear resistance, high corrosion resistance and high volume density, grinding efficiency higher characteristic, it can except used in great quantities of ceramic powder grinding and in other electronic ceramics powder, magnetic powder, high technology structure and functional ceramics powder, ceramic pigment and glaze, chemical industry and all kinds of coating, mechanical polishing powder, powder, medicine and food, and in the ultrafine grinding of special inorganic material powders also played an extremely important role.
