"This work focuses on the characterization of heat generation during dry fracture by direct impact of a tantalum ore. Moreover, an attempt was made to quantify the heat energy loss to the environment during the grinding process of a ball mill. The study was carried out using mineral samples from a Spanish mine that were characterized by …

The effect of ultrafines generation in the ball mill on power consumption for each shift is shown in Figure 3. It is found that the power consumption can be reduced to below 280 kWh for a shift at a feed rate higher than 40 t/h. It is also observed that with an increase in the feed rate, ultrafines generation in the ball mill decreases. The ...

The majority of grinding balls are forged carbon or alloy steels. Generally, they are spherical, but other shapes have been used. The choice of the top (or recharge) ball size can be made using empirical equations developed by Bond (1958) or Azzaroni (1984) or by using special batch-grinding tests interpreted in the content of population …
