2021 pricesd) Energy required is directly proportional to the surface to volume ratio Answer: a Clarification: Bond''s law states that the work required to produce particles from large particle size is directly proportional to the square root of the surface-to-volume ratio.

2021 pricesAbout 30% of the energy required to produce one ton of cement is consumed in grinding. It is a significant percentage of the total cost of cement. The energy consumption in the cement mills varies between 16.5 to 63.5 kWh/ton with an average of 36kWh/ton [1].

2021 pricesAbstract The Bond work index, Wi, as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding product. Therefore, in practice we can expect some difficulties and errors when the energy consumption is determined according to this formula in the case when, for a given size of grinding product, the value of the work ...
