Ball Mill Power Consumption Vs Blaine Most existing ball mills designed for grinding portland cement are not a vertical roller mill than for the ball mill depending on the required blaine2 for the slag research concludes that lowering the ball mill filling percentage negatively affects mill

MoreIntuitively, I would prefer the Blaine to correlate with power consumption. That's because, I spnotaneaously think that grinding is about creating surface and this is what the power consumption goes to but with a very bad efficiency!

Morereducing the blaine and thus increasing the mill production. The optimal production can be obtained with ease by varying the blaine within the required range. Blaine control is achieved by varying separator motor speed (revolutions per minute). The higher the speed the higher the blaine and hence the higher the power consumption.

MoreMar 01, 2006· For a given specific energy consumption, the Blaine specific surface and the energy efficiency concerning this size fraction are greater with 10 mm balls than with 20 mm balls. In a previous study [7] performed with the same clinker on the size class (1–0.71 mm), it was shown that the reduction size rate was maximum with the 20 mm balls.

Moreconsumption (SEEC) of about 5 kWh/t on mill motor power consumption at a mill motor total SEEC of 30 kWh/t. This results in a loss of 16%, simply due to completely deformed second chamber media. In many site visits observed by the author, although plant operators have carried out ball sorting, mainly only ball classification was carried out.

More2. Higher grinding efficiency, lower power consumption . The optimized roller, millstone and inner airflow guidance design greatly improve the grinding efficiency. The capacity of LUM ultrafine vertical grinding mill is 30% higher than similar products and the power consumption is 30%-60% lower than ball mill
