The amount and type of contamination of material ground is directly related to the wear resistance of the grinding media. Numerous factors must be considered when evaluating the rate of wear. Such variables as starting size, distribution of feed, mill speeds, grinding media loads, pulp residence time, pulp density, hardness of media, amount of surface area of media, specific gravity of the media, hardness of the material being ground, specific gravity of material ground, desired particle size of the material ground and grindability all contribute to the complexities of establishing wear data.
In the past, steel has traditionally been used as grinding media material, it is fast being replaced by tungsten as the preferred material. Tungsten carbide media shows a lower rate of wear than the steel, while the grinding rate for tungsten carbide media was proportional to the specific gravity.
Tungsten carbide grinding media is however a perfect fit, considering the demand for a material which has superior strength, resistance to abrasion and corrosion as well as tolerance for high-temperature ranges.
Grinding media - WC balls
Tungsten carbide crystals which are also known as grinding media are available as spherical and precision ground to a specific diameter. Tungsten carbide balls in different sizes depending on the grinding needs. The material also has superior qualities of its high hardness HRA 92.5 as well as an exceptionally high density sp.gr.15
Spherical grinding balls is usually as tungsten carbide grinding media , available in different state conditions like 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.
Tungsten Carbide Grinding Media – Ball’s Variety of Sizes (0.4-20mm)
Grinding balls of diameters from 0.4mm to 20mm available to meet all kinds of requirements of planetary ball mills . High hardness , can meet majority of metal powder crushing and refining.
Within the grinding and milling industrial applications, the need to homogenize resilient products using stronger materials is immense. While steel has been traditionally used, it comes with its own drawbacks.tungsten carbide are twice the density of stainless steel. Thus, for samples which are very resilient, tungsten carbide grinding balls are a good alternative to stainless steel balls. Meanwhile, tungsten carbide media shows a lower rate of wear than the steel.
Reasons for high demand
So, what makes tungsten carbide a highly demanded material when it comes to choosing grinding media? Some of the following factors contribute to the same:
1. High resistance to wear and abrasion making it cost effective
2. High specific gravity
3. Fine polish which makes it easy to clean, especially in industrial processes
4. High resistance to temperature, corrosion, etc.
5. Extreme hardness and density which makes it a perfect grinding material.
While it is true that the comparative cost of tungsten carbide grinding media for oil industries is higher than its traditional counterparts like steel, the long life span along with the other features mentioned above make it a more cost-effective choice in the long run.
