It is also a cheaper and more efficient process, compared to both crushing and grinding. One of the most valuable aspects of blasting is the generation of very fine particles (e.g., smaller than 12mm) that will pass through the primary mills and onto the secondary ball mill circuits, alleviating a common bottleneck.

Calculate the Reduction Ratio and the Number of Milling ...
The milling work is done in two circuits, crushing and grinding. The grinding reduction ratio is very higher than the crushing. Besides, each stage product is the feed for the next stage, and usually, the reductio ratio becomes higher as far as we go finer. These are useful information for you when dividing the global ratio into multiple values.

Crushing Circuit - an overview | ScienceDirect Topics
The first step of physical beneficiation is crushing and grinding the iron ore to its liberation size, the maximum size where individual particles of gangue are separated from the iron minerals. A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure 1.2.2 (based on Ref. [4]).This type of flow sheet is usually followed when the crude ore contains below 30% iron.
