In laboratory grinding studies, the rotational speed of the ball mill was chosen to be 70% of the critical speed value of the ball mill. The critical speed of the ball mill was calculated using Eq. 3. Amounts of ball and material to be fed to the mill with Eqs. 4–6 respectively and the mill's interstitial filling rates were found.
Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of …

Also there is apt to be more settling of sand fractions which may cause mechanical difficulties when treating a dilute pulp. Accordingly agitator densities are usually kept from 30% to 60% solids, Grinding capacity in a ball mill is also limited if the density drops below 70% solids. What is the Effect of Aeration on Gold and Silver Leaching

on what type of mill to choose. Trying to grind a material which is too hard, such as sand in most types of beater mill, will result, either in costly damage to the mill or an expensive maintenance requirement. Most types of readily available hammer mills for agricultural grinding are not suitable for grinding most types of minerals.
Each grinding balls are round balls with precise dimensions. The sizes of Fote grinding steel balls can be designed according to customer requirements. Generally, the ball diameter is between 20mm and 125mm. You can also design 10mm, 11mm or other diameters of steel balls. Small steel balls: 40mm or 60mm.
