Autogenous and Semi-Autogenous MillsScienceDirect

   It can therefore be concluded that autogenous grinding was not suitable with this particular gold ore but semi-autogenous operation with about 8 ball charge was the preferred option. Based on these test results a 6.7 m diameter 2.1 m length SAG mill and a 3.3 m 6.1 m ball mill were installed for commercial operation in closed circuit

Global Mining Guidelines Group Industrial Comminution

The Industrial Comminution Efficiency Sub-Committee aims to provide tools for practitioners to measure the energy efficiency of comminution circuits using standardized metrics and methodologies. The guidelines developed by this group aim to define the recommended methods for quantifying grinding circuit efficiency using grinding power analysis

Questions and answers on grinding technologyMining

   This media consumes mill volume and power but the grinding is very inefficient due to the motion of the charge. All of these factors add up to inefficient use of energy. The solution to this would be to conduct ongoing calculations to ensure the optimal size of grinding media is used and to keep a close eye on media quality.

In order to contin-uously optimize mill operation it is vital to obtain regular measurements of the ball load and pulp position. The current way to measure the charge filling degree

Siemens Supplies Gearless Drive Mining Technology

   The procedure developed by Siemens is used for controlled detachment of frozen (hardened) charge stuck to the inner wall of the mill shell defined forward and reverse movements of the mill loosen the sediment. The frozen charge no longer has to be detached by hand in the tube. This shortens down times and increases availability.

   thicker and thicker as the speed increases until the entire charge is centrifuging and the net power draw is zero. The effect of mill charge is primarily through the shifting of the center of gravity and the mass of the charge. As the charge increases the center of gravity moves inward. The power draft is more or less symmetrical about the 50 value.
