Application of Different Grinding Media

Jul 18, 2023

The selection of grinding media is a very important issue in the ultrafine grinding process, as different grinding media have different chemical elements. In the actual production process of grinding, we first need to pay attention to whether the chemical composition of the grinding medium will react with the grinding material to avoid material pollution. For example, in the fields of grinding pesticides, pharmaceuticals, and biochemistry, heavy metals are considered as elements and media containing heavy metals cannot be chosen. Secondly, when grinding Superhard material such as silicon nitride, silicon carbide, etc., consider using grinding balls of the same medium as far as possible.

As one of the major grinding medis suppliers out there, we can produce various types of milling options in different sizes. Hereby pls check some of our best-performing balls and beads as follows;

Grinding Media	Feature	Common Equipment
Al2O3 Grinding	With wear resistance, corrosion resistance, high temperature resistance, impact resistance and other excellent performance.	Widely used in white cement, mineral processing, ceramics, electronic materials, magnetic materials, as well as coatings, paint and other industries of raw materials powder grinding processing.
ZrSiO4 Grinding	Compared with ZrO2 medium, it has high wear and low strength, so it lacks good market promotion prospects.	It is mainly used for ultrafine grinding of ZrSiO4 raw materials. It is the preferred grinding medium for ultrafine grinding of ZrSiO4, with a certain cost performance.
ZrO2 Grinding	High density, large impact force, high grinding efficiency; The surface is smooth and hard, the wear is small, so as to avoid the product pollution; Can reduce the required grinding time, suitable for wet grinding.	Used for "zero pollution" and high viscosity, high hardness material ultra-fine grinding and dispersion, such as: electronic ceramics, magnetic materials, zirconia, silica, zirconium silicate, titanium dioxide, medicine and food, pigment, dye, ink, special chemical industry.
Silicon carbide Grinding	It has the advantages of high strength, high hardness, oxidation resistance and corrosion resistance at high temperature.	Can be used for all kinds of powder material ultrafine grinding, such as silicon carbide ultrafine powder, and all kinds of precision bearings.
Silicon nitride Grinding	High oxidation resistance; The hardness, compressive strength and elastic modulus of zirconia ceramics are much higher than those of zirconia ceramics.	It is an indispensable grinding medium in the production of silicon nitride powder and is widely used. At the same time, more suitable for sand mill, vibration mill and other high-energy ball mill equipment.
