Impact of free lime on grinding efficiency - Page 1 of 2

2011-8-8  Re: Impact of free lime on grinding efficiency. Hello Pankajbits, All other factors being equal, low free lime clinker (hard burned) is generally harder to grind than clinker with higher free lime. This is due to physical changes in clinker mineralogy and porosity caused by over-burning rather than the presence of the free lime itself.
