The industries that typically use Grinding Media are the mining and construction industries. Grinding Balls are used in ball mills. They are useful when breaking down and grinding materials such as rocks, cement, and others.

Some markets that use grinding media include:

  • Mineral processing
  • Construction sector
  • Road construction
  • Ore crushing
  • Manufacturing process

How to Determine Suitable Grinding Media

Grinding media has recommended characteristics, involving the shape, size, and composition. Steel grinding balls characteristics should include:

Shape – The shape of grinding media is typically a sphere. This form is highly dense and does not chip easily. There are two shapes of grinding media that are most efficient. These include the ball shape and the cylinder rod.

Diameter – The grinding ball should have a smaller diameter, but still large enough to get the best results. It can be more accurate when breaking down other material. The size of forged steel grinding balls will generally range from ¾ inch to 5 inches in diameter. The size of grinding rods will generally be between 1.5 to 4 inch in diameter. Also, the length should be a few inches shorter than the mill length. The size needed for each job may vary.

Composition – The grinding material needs to be able to withhold high grinding methods and not wear or chip quickly. The grinding material should have a greater density than the material that is being ground. The material of the grinding media may vary, as well. Camasteel sells forged steel grinding balls, cast iron grinding ball, and steel grinding rods.

How to Manufacture Steel Balls?

Camasteel uses a forging and stamping method to heat the metal to 1050 degrees Celsius. Then, it can be molded into the sphere shape. Between the forged steel grinding ball and the cast iron grinding ball, forged steel has better mechanical performance. The forged steel grinding ball must use the super wear resistant material to ensure its durability.

When making the steel ball

  1. Heading: short lengths of wire are cut and then it is shaped into the form of a sphere.
  2. Deflashing: the ball rolls between two very heavy plates, typically cast iron plates, and becomes formed.
  3. Soft grinding: this is similar to the deflashing step, but a grinding stone is used to make the more precise form.
  4. Hot treating: the steel balls are put through heat and hardened.
  5. Descaling: removing any undesired residue from the ball.
  6. Hard grinding: this step helps with providing the perfect size and shape for the order.
  7. Finishing: giving the balls a smooth finish and coating to ensure that the product will last long.

Before the product is ready to sell, there is a quality inspection test that occurs. This consists of:

  • Dropping test
  • Hardness test
  • Chemical Element Analysis
  • Impact Value Test

These tests ensure that the steel ball will be efficient in the mills.

The product is cleared for shipping, then it is packed in bags and loaded on a truck to be transported to its destination.
