Crushing and Grinding Process JXSC Machine

The 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 50% to 65%, and steel consumption is as high as 50%.

Crushing Vs Grinding Minerallurgy

Energy. Both crushing and grinding require energy to reduce the ore size. However, in grinding operations we consume much more eneregy than crushing, up to 100 times ( thousands of kw compared to tens in crushing). Because as far as we go to finer size we need more force and collosions for further size reduction. In fact grinding is the most consume energy section for the whole processing

Energy considerations in compressive and impact

1/8/2008· But in a mine, the cost and energy consumption associated with fine grinding are considerably larger than those associated with the compressive crushing. This difference in cost and energy consumption has essentially two explanations. As the particle size is reduced, the specific surface area increases. As the particle size approaches zero, the number of particles and specific

To relate energy consumption and grinding fineness in the grinding process, Rittinger [9] proposed that the amount of energy consumed during mineral crushing is proportional to the amount of fresh surface area on the mineral. Kick [10], however, was of the opinion that the amount of energy consumed during mineral crushing is proportional to the change in volume of the mineral. Later, Bond [11
