Jan 01 1989 INTRODUCTION The energy consumption for grinding according to Bond 1961 is deter- mined by the formula 10 10 I The work index is determined by grinding experiments carried out in a labo- ratory Bond ball mill. Based on the results of grinding experiments numerical values of the work index Wi are calculated according to the formula.

The Simple SAG Mill is a machine added by Ender IO. It uses Micro Infinity I to grind or mill items into their crushed variants like Ores into Dusts. The Simple SAG Mill has four output slots; recipes can have 1-4 different outputs with different chances of obtaining those outputs. Similar to Ender IOs other Simple machines capacitors cannot be used in the Simple SAG Mill so its.

• ### Best energy consumption International Cement Review

Feb 16 2015 Grinding energy was approximately 50 per cent of the ball mill and the drying capabilities allowed direct processing of materials of up to 20 per cent moisture content. The main energy issue was the high power consumption of mill fans with pressure drops of 100mbar not uncommon with high nozzle ring velocities 70ms and internal mill.

That is the SAG mill produces about 10.76 more than the ball mill in the final product. The average consumed energy at SAG and ball mills to produce one ton of final product was 23.16 kWht and 36.05 kWht respectively. Thus the ball mill consumes 12.89 kWht more energy than the SAG mill in producing the final product.
