Grinding ball usually has a high hardness,can resist wear and deformation,to maintain the stability of its shape and performance,for example,alumina ceramic grinding ball with its high quality alumina as the main component,has a high Rockwell hardness,second only to diamond,more than wear-resistant steel.
Grinding ball is widely used in many industries,including but not limited to raw material processing,quartz processing,glass manufacturing,lithium battery material processing,silicon powder processing,oil and gas mining equipment and other industrial fields.the grinding ball is especially suitable for the treatment of hard materials,to avoid the introduction of metal impurities,for grinding and processing white cement,minerals,ceramics,electronic materials,magnetic materials,coatings and paints and other raw materials.
