Mainly, we produce grinding media ie steel grinding balls and steel cylpeps, used in ore processing industry, cement plant, power station and more. Our steel balls and cylpeps are used in preliminators, tube mills, as grinding medium, to crush copper stone, calcium, coal and other matals ore. For example in copper mine, bauxite, gold mines.
Then wet grinding in semi-autogenous rod or autogenous ball mills takes place. Size classification takes is performed in cyclones. In the next step of beneficiation, valuable minerals and gangue are separated by froth flotation of the ore pulp, which exploits the different surface properties of the sulfidic copper ore and the gangue [46].

Figure 10.1 shows the difference in energy efficiency between a laboratory ball mill and a stirred mill grinding a gold ore using 6 mm diameter alumina balls as media. At a fine grind size there is a clear advantage in energy consumption for a stirred mill over the tumbling mill. However, as the grind size coarsens, the difference in specific energy required to achieve the grind lessens.
In Poland, architects Ingarden & Ewy have achieved a similar look to rusted steel with the Pavilion Wyspianski, built in 2000 in Krakow. Here, the rust color is actually a result of special facade bricks which help the building blend with its brick-built Gothic church neighbors.
The paper discusses a recent find of a copper alloy light cannon discovered at the Old Castle in Grodno, Belarus. The research aim was to analyse the artefact in all its possible aspects, including archaeological and historical contexts, possible analogies, and the gun's technology of manufacture. This latter was done against a broad comparative background of what is known on …
12%In this work, Fe-Mn-Cu-Sn-C alloys were prepared by means of powder metallurgy (PM). Powder mixtures were ball-milled for 8, 30 and 120 h and densified to < 1% porosity using spark plasma sintering (SPS) at 900 °C and 35 MPa. After consolidation, all samples of the Fe alloys were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), …

was ball-milled in air for 8, 30 and 120 hours at 70% critical speed. About 50% of the milling container was filled with 12 mm hardened 100 Cr6 steel balls and ~10:1 ball-to-powder weight ratio was used. After ball milling the powders were tested for particle size and shape, and examined metallographically. The results are shown in . Table 1 ...

Ball or rod mills crush and grind the mined ore to fine particles that may be only microns (10-3 mm) in diameter, releasing molybdenite from the gangue (worthless rock). The grinding mills on the right reduce rocks the size of soccer balls to the size of gravel. Further ball milling reduces the material to the consistency of face powder.
