The importance of size reduction and agglomeration

We see that 1% of the world’s electrical energy is expended in the crushing and grinding of cement Mills don’t operate in an\ഠoptimum manner and most of the energy is wasted anyway! Oh, forThe crushing and grinding operations are an important part of the processing of mineral resources, and it is also operation with high investment and high energy consumption In the case of metal mines, equipment investment in crushing operations accounts for 65% to 70% of the total plant value, power consumption is about Crushing and Grinding Process JXSC Machine
