Grinding circuits with fully autogenous (AG) or semi-autogenous (SAG) mills, often combined with ball mills are now the standard to meet the high capacity requirement for processing ores with lower metal grades. Simulation software and power-based equation methodologies have been established for designing AG/SAG based grinding circuits and predicting their energy requirements. Presently, power

Is there a general rule or a formula to calculate the ideal %ball charge in a SAG mill? Grinding Ball Mill In Chile . Ring gear drives huge grinding mill Mechanical Drives / Ring gear drives huge grinding mill or an intermediate size ready for final grinding in a secondary ball mill Ball Mills. This formula calculates the critical speed of any ball mill Most ball mills operate most

Depending on the mill size the SAG mills draws between 2 MW and 17 MW. The product from the SAG mill is further reduced in size using pebble crushers and ball mills. Hence, typical gold or copper ore requires between 2.0 and 7.5 kWh per ton of energy to reduce the particle size. Considering a typical mining operation processes 10,000 to 100,000 tons per day the energy expenditure in grinding

The ball charge of a SAG mill is about 29% to 30%. By friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness. The internal machinery of ball mill grinds the raw material into the powder-like material, And if extreme fineness and refinery are required then rotation go on continue. Image Source: Application In the production of Portland

SAG mills of comparable size but containing say 10% ball charge (in addition to the rocks), normally, operate between 70 and 75% of the critical speed. Dry Aerofall mills are run at about 85% of the critical speed. The breakage of particles depends on the speed of rotation. Working with a 7.32 m diameter and 3.66 m long mill, Napier-Munn et al. [4] observed that the breakage rate for the finer

ball mill can be re-organised as 7 and 8 where B Wio and A Wio are the corrected operating work indices and WAG/SAG WBM are the respective power draw of AG/SAG and ball mills. Note that the ball mill operating work index is applied only on the portion that needs the additional grinding (Q2) which renders to the AG/SAG mill the. Chat Online

But we are seeing more and more major copper and gold operations now taking advantage of composite liners in large SAG mills," says Jack Meegan, Product Line Manager for Liners and Wear Parts in FL. For a customer in South America, FL recently replaced a chromoly liner in a 40 ft SAG mill with a rubber ceramic composite liner. This improved the slurry discharge by 6%. "Many

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The % loading or change volume can then be read off the graph below or

Figure 2: Pilot Plant kg/hr Vs Charge % by Volume This data is indicative of trends that were happening in the 3-ft. diameter SAG pilot mill. They have not been proven in large commercial scale mills. Because the grinding operation could be viewed through the open end of the SAG mill, it was evident that maximum throughput occurred

The motion of an individual ball in the charge is complicated in practice and it is not possible to calculate the path taken by a particular particle during station of the charge. However the general pattern of the motion of the media can be simulated by discrete element methods which provide valuable information about the dynamic conditions inside the mill. Some of the terms that are often
