The world market for grinding balls is about 5 million tons. According to forecasts from analytical publications, by 2025 consumption of grinding balls is expected to increase substantially. This is primarily due to an increase in the production of iron and non-ferrous ores and an increase in industrial construction. For example, while world production of iron ore was 3 billion tons in 2020, it is expected to increase by 571 million tons by 2025.
It should be noted that due to the gradual depletion of the raw material base for the extraction of the useful component, it is necessary to process the rock in increasing volumes and to grind the ore more carefully. Grinding balls tend to wear out (from 0.5 to 2 kg/t) and their acquisition costs are estimated to be between 20 per cent and 35 per cent of the total production costs. In view of this fact, the increasing durability of grinding balls over the past few years has become increasingly urgent.
«Energosteel» Company follows this trend, constantly improving the quality characteristics of steel grinding balls produced by our plant. Thus, we have mastered industrial production of steel grinding balls of increased volume hardness. Grinding balls of increased volume hardness have equally high hardness indices all over the ball – from the surface to the center, which makes it possible to reduce the percentage of wear to minimal values and, therefore, to save the cost of their acquisition from consumer enterprises.
