scale up of power consumption in agitated ball mills
Best energy consumption International Cement Review
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 (>70m/s) and internal mill circulating loads of >1000 per cent.
Charge behaviour and power consumption in ball mills ...
Discrete element method (DEM) modelling has been used to systematically study the effects of changes in mill operating parameters and particle properties on the charge shape and power draw of a 5m ball mill. Specifically, changes in charge fill level, lifter shape (either by design or wear) and lifter pattern are analysed. The effects of [.]

The SAG mill specific energy consumption is deducted from the total circuit specific energy consumption to get the ball mill specific energy consumption: E bm =E total −E SAG (8) Determine Mill and Motor Size Knowing the SAG and ball mill specific energy consumption allows mill sizes to be calculated if a desired throughput rate is known.
Ball Mills Cylindrical Ball Mill Manufacturer from Meerut
The larger the diameter is, the slower the rotation will be. Ball Mills are generally used to grind material ¼" and finer, down to the particle size of 20 75 microns. To achieve reasonable efficiency, the ball mills are to be operated in a closed system, with oversize particles continuously being recirculated back to the mill and to be reduced.
IsaMill Wikipedia
very high power intensities – IsaMills operate at power intensities up to 350 kilowatts per cubic meter ("kW/m3"). For comparison, the power intensity of a ball mill is about 20 kW/m3. This high power intensity allows the IsaMill to produce fine particles at a high throughput rate.

The Small Pebble Process for Reducing Ball and Power ...
The Small Pebble Process for Reducing Ball and Power Consumption in Secondary Grinding . Ball mills are used widely for secondary grinding. A mixture of ball sizes can be used to optimise grinding efficiency, but the use of balls smaller than about 30 mm in diameter is not normally viable, particularly when alloy steel is required.
