The company “ENERGOSTEEL” completed the industrial test of grinding balls 40 mm of the fifth group of hardness (DSTU 3499-97) on the base of one of the largest manufacturers of aerated concrete in Azerbaijan in August 2016.
Tests were carried out over one year, which minimized the impact of various factors that have an influence on the specific consumption of grinding media (for example, the performance of the ball mill, the quality of raw materials, etc.).
Analysis of the results of a sufficiently long period of testing has shown that the difference in the consumption of steel grinding balls of the fourth and fifth groups of hardness was more than 20%.
Based on obtained result, the management of the partner company decided to permanently use grinding balls 40 mm of the fifth group of hardness (DSTU 3499-97) produced by “Energosteel”.
