Energosteel Company continues series of articles for inform our readers about measuring the bulk weight of steel grinding balls produced by Energosteel.
A batch of 120mm steel grinding balls was produced in November. This is the maximum grinding balls diameter used in Ukraine. Grinding balls this batch corresponds to the fourth hardness group (DSTU 8538: 2015 / DSTU 3499-97). The measurements results have shown in the table below.
Table 1. The 40mm grinding balls bulk weight. (without shaking up)
| Parameter | Container №1 |
| Container volume, m3 | 1,531 |
| Grinding media volume in container, m3 | 1,471 |
| The container and grinding media weight (gross), t | 7,475 |
| The container weigh, t | 0,880 |
| The grinding media weight, t | 6,595 |
| The bulk weight, t/m3 | 4,486 |
The 120mm grinding ball bulk weight is 4,52 t/m3 in reference specialized literature.
Let’s summarize our articles series where we have reflected measurements results the bulk weight of steel grinding balls produced by Energosteel. You can see the bulk weight parameters of 40mm, 50mm, 80mm, 100mm and 120mm grinding balls in our articles. In the near future, we will conduct similar measurements on the 30mm and 60mm grinding balls. We hope, the obtained information will be useful for our readers. Upon completion the articles series about grinding balls bulk weight measurements, we will provide you a consolidated table with all bulk weight indices of steel balls the whole Energosteel production range.
