Crusher Fines. Fines—sometimes called crusher fines —are small particles of crushed rock that include a mix of sizes, from a fine dust up to 3⁄8 inch (about 9.5 millimeters) in diameter. Often, crusher fines are leftovers from crushing operations, but they can be custom produced. Using crusher fines alone contributes to dusty conditions.

® Crushing Equipment |
The reduction ratio of a horizontal impact crusher is much higher than that of a jaw or cone crusher. The ® APP series is the larger of the two crushers and is used for primary stage crushing of larger feed sizes. It is a very versatile machine, but does not produce as fine a product as the ® APS series.
Exploring Jaw Crusher Efficiency | Kemper Equipment
Either an 8-to-1 or 6-to-1 ratio should be the target reduction ratio for maximum jaw crusher efficiency. This setting typically provides an ideal P80 factor—when 80% of crushed material produced by primary crushing will pass screening after processing. ... There are many ways to fine-tune jaw crusher efficiency and production. However ...
Roll Crusher
Unless very large diameter rolls are used, the angle of nip limits the reduction ratio of the crusher, and since reduction ratios greater than 4:1 are rare, a flowsheet may require coarse crushing rolls to be followed by fine rolls. Smooth-surfaced rolls are usually used for fine crushing, whereas coarse crushing is often performed in rolls ...

How to Optimize Reduction Ratio in Jaw Crusher?
The reduction ratio is a critical parameter for the performance of a jaw crusher. It affects the capacity, quality, and energy consumption of the machine. A high reduction ratio means a smaller product size and more fines. It also implies higher crushing force and energy consumption. On the other hand, a low reduction ratio means a larger ...
