The company “Energosteel” is focused on building long-term and strong partnerships. We not only provide high-quality service, prompt response to inquiries, effective solution of various issues, but also hold personal meetings with partners at their production sites.
This format allows our technicians to evaluate the produced grinding balls during operation, to evaluate the efficiency of the grinding process (correctly selected particle size distribution, load rate of ball mills, current load schedule, etc.).
Therefore, in September 2019, as part of annual personal meetings, the technical specialists of Energosteel visited our partner, one of the largest mining and processing companies in Azerbaijan.
The history of relationships with this client is quite eventful. The ore that is mined at this enterprise has some specific features – it is significantly harder than ordinary quartzite and very abrasive. To correctly select the parameters of grinding bodies (we are talking about balls with a diameter of 40 mm) for this particular case, we conducted several tests, the results of which clearly determined the chemical composition of the steel of grinding bodies and the necessary hardness parameters, which showed maximum efficiency in grinding in second stage. In the first grinding stage, SAG mills loaded with 120 and 100 mm balls are used, and the exact proportions of the load are not regulated and the choice of the ball for reloading depended on the results of mine surveying incoming ore. The choice of the diameter of the grinding media was not always correct, there were cases when the 120mm ball was too large (there were isolated cases of splitting), and the ball with a diameter of 100mm did not give the necessary grinding. In this regard, the company Energosteel has mastered the production of steel grinding balls with a diameter of 110 mm, which are currently delivered to our partner.
We thank our client for such a warm visit and productive collaboration!
