operating a mill on load vs power
Aug 07 2017 · What’s the difference between the installed capacity and electricity generation of energy sources It’s a good question and one that’s commonly misunderstood In the energy world these two terms are often used to describe the growth of energy resources in the United States Take wind or solar for example
I believe that as circulating load in a ball mill increases beyond a critical point the mill power draw begins to fall so there is an adverse effect on grinding efficiency apart from the obvious physical problems it causes like high scats rates balls discharged from mill sumps overflowing cyclones clogging up
