Why tungsten carbide is better than steel for making grinding balls?

Tungsten carbide grinding ball

While steel has traditionally been used for the purpose of industrial grinding balls, it is fast being replaced by tungsten as the preferred material. Tungsten is used as both tungsten alloy as well as tungsten carbide for making high strength grinding balls for various industrial applications. Tungsten carbide grinding balls are used in the oil industry and offer multiple advantages in comparison to the traditional options like steel.



The use

Tungsten carbide grinding media

Tungsten carbide grinding balls are used to homogenize large and resilient products which cannot be managed with the help of smaller grinding beads. Tungsten carbide grinding balls are spherical with varying diameter ranges. While steel is also used for the same purpose, tungsten carbide grinding balls for the oil industry is highly demanded owing to their high density and hardness along with other features like abrasion resistance.


Features of tungsten carbide grinding balls

Tungsten carbide grinding balls are available in different sizes ranging from 0.4mm to 4” along with a high tolerance of +/-0.02 and a density higher than steel ranging from 17.0-18.8g/cm3. WEISON is the leading manufacturer and supplier of tungsten carbide grinding balls for oil industries around the globe.

Meeting the stringent international standards, WEISON products including tungsten carbide grinding balls come with features like high hardness, bending resistance, wear resistance, rust free, etc.

Different state conditions are available within tungsten carbide balls suitable for different industrial applications. These include the sintered tungsten carbide balls, the rough grinding tungsten carbide balls, the grinding tungsten carbide balls, the high precision tungsten carbide balls, and the smooth grinding tungsten carbide balls.
Usually produced with grade YG6 and a hardness level of HRA91.0, these are widely used in the oil industry for different grinding and milling applications.

What makes it better than steel?

Further, some of the key features which make tungsten carbide balls a favorite within the oil industry include:

1. High-cost effectiveness due to low wear and minimal maintenance
2. High efficiency
3. High specific gravity
4. High hardness to meet the crushing and grinding requirements within the industry
5. Highly polished, easy to clean
6. Resistant to high temperatures, abrasion, etc.

The use of tungsten carbide grinding balls for the oil industry, although costlier than traditional materials like steel is still being considered as more cost efficient in the long run owing to its long life span and low maintenance requirements.
