Bond formula for the grinding balls size calculation
Material grinding in the aerated concrete production
Energosteel Company specialists continue to inform our readers about measuring the bulk weight of steel grinding balls produced by Energosteel.
Recall, our production department has been equipped with two containers in order to measure the bulk weight of grinding balls. Both containers (tubs) have the correct geometric shape – a parallelepiped with sides 118х118х110cm. The each container volume is 1.53 cubic meters.
Thus, a batch of 40mm steel grinding balls the fifth hardness group (DSTU 8538: 2015 / DSTU 3499-97) was produced in September. The measurements results have shown in the table below.
Table 1. The 40mm grinding balls bulk weight. (without shaking up)
| Parameter | Container №1 | Container №2 | Average value |
| Container volume, m3 | 1,531 | 1,531 | |
| Grinding media volume in container, m3 | 0,989 | 1,002 | |
| The container and grinding media weight (gross), t | 5,625 | 5,615 | |
| The container weigh, t | 0,950 | 0,880 | |
| The grinding media weight, t | 4,675 | 4,735 | |
| The bulk weight, t/m3 | 4,730 | 4,726 | 4,728 |
The 40mm grinding ball bulk weight is 4,76 t/m3 in reference specialized literature.
Energosteel Company will continue to inform you a calculation results the bulk weight of steel grinding balls with different diameters (from 25mm to 120mm) own production.
