- Crusher Reduction Ratio - Mineral Processing & Metallurgy
Crusher Reduction Ratio I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged.

- Urea Reduction Ratio - an overview | ScienceDirect Topics
The most simplified and widely utilized measure of dialysis dose is the urea reduction ratio (URR) described by Lowrie. The URR is the percentage of reduction in the blood urea nitrogen (BUN) over the course of a single hemodialysis treat-ment. The extent of the reduction in BUN reflects dialytic urea clearance adjusted for body water (V).

- Gear train - Wikipedia
Considering only these gears, the gear ratio between the idler and the input gear can be calculated as if the idler gear was the output gear. Therefore, the gear ratio is driven/drive = 21/13 ≈1.62 or 1.62:1. At this ratio, it means the drive gear must make 1.62 revolutions to turn the driven gear once.
