This study aimed at improving the tribological and thermal properties of Al alloy using CNTs and Nb nanopowder as reinforcements and spark plasma sintering (SPS) as the fabrication method. The SPS was conducted at 630 °C, 30 MPa, 10 min, and 200 °C/min. The tribology test was run with ball-on-disc tribometer using steel ball as the counter body.

2018. Albertin, E. In the mining industry, abrasion is the most significant wear mechanism. The resistance to abrasion is a property that must be combined with other material properties, such as toughness and corrosion resistance. In the crushing, grinding and material handling operations, the most relevant wear resistant materials are steels ...

The SAG mill and the gold plant can run independently without the ball mill and did so at about 60% of its capacity during the summer before the ball mill came online. Maximum throughput using this configuration will only be known once the SAG mill's capacity is optimized using this power configuration.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

Ball consumption is mainly due to wear in ball grinding mills and also due to fracturing in SAG mills (approximately 10%) . In large-size SAG mills (1158.24–1219.2 cm in diameter), ball fracturing can account for a higher percentage of consumption due to increased impact energies. In these cases, the ball quality becomes more important.
