About the hardness

How hard is hard? The illustrations shown below tell an interesting story. Illustration ‘A’ shows an analysis of the cross sectional hardness of The Steel Ball Company’s ‘thru hard’ ball. Illustration ‘B’ below shows the same analysis carried out on a ball from another major grinding media manufacturer. The ball in illustration ‘B’ has the same AVH figure as The Steel Ball Company’s ball and will wear out at the same time. Yet there the similarity ends. After three quarters of the radius, the hardness of the ‘B’ ball dips below that of The Steel Ball Company’s ball. This brings into focus the area of greatest discussion about using AVH values. Over 72% of the final value is made up from the surface and 3/4 radius hardness readings. So AVH tells us relatively little about how a ball is going to perform once it has worn past that stage.

The cross sectional hardness profile tells the full ‘inside story’.

Q What kind of performance will the ball in illustration ‘B’ below give?

A Once the ball has worn down to approximately 2/3 diameter, the remainder will wear away very quickly.

Q How will this affect the mill output?

A The rapidly wearing grinding media will give rise to an unstable and imbalanced ball charge, resulting in the possibility of more than one top up size being required to ensure the correct mesh of grind.

Q How will The Steel Ball Company’s ball perform?

A The cross sectional hardness profile shows that The Steel Ball Company’s ‘thru hard’ ball will wear evenly throughout its life. This will give a better size distribution in the mill, and avoid ‘dead zone grinding’. The shape of the ball will be preserved for much longer, giving a far more efficient grind. The conclusions are obvious. High quality such as The Steel Ball Company offers always saves money in the long run.

 don’t mix our products with those of other companies,or it will be subject to deformation.

2.Please control the grain size of raw materials and the proportion of grinding materials to grinding 

medias.Unreasonable proportion is bad for the use of our products.

3.When using the products,please do not pursue product fineness at the cost of reducing the output .

Otherwise ,our products will be exfoliated and out of shape.

4.In the process of using our products,the mill could not be opened or stopped frequently,or operated

 without any materials in it.Before putting the casting balls into the container,please put some materials

 in the lowest floor in case of breakage,clashing and so on.

5.Open the door of the mill at first and pour the balls out when the temperature in the mill falls down .

6.If you find something unusual in the process of using,please contact us immediately and we will arrive

 on the spot as soon as possible.
