how to calculate reduction ratio of planetary gear
The reduction ratio, also known as gear ratio of a planetary gear set, is a critical parameter in the design and operation of these advanced mechanical systems. To calculate this ratio, you need to divide the rotational speed of the input (sun gear) by the speed of the output (ring gear). For a more comprehensive view, the formula is: Reduction ...

Reduction Ratio Equation For Cone Crushing
The operation is similar to the standard cone crushers, except that the size reduction is caused more by attrition than by impact [5] The reduction ratio is around 8:1 and as the product size is relatively small the feed size is limited to less than 50 mm with a nip angle between 25° and 30°The right one for primary crushing often depends on ...
Tips for maintaining efficiency in crushing circuits
Crushing setting: Efficiency. Ideally, the reduction ratio of a jaw crusher should be 6:1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 per cent versus the discharge size that passes 80 per cent.

Gear Ratio Calculator
Following our gear ratio equation, we can say that this gear train has a gear ratio of 40:10, 40/10, or simply 4/1 (or 4). This gear ratio means that the input gear would need to rotate 4 full turns for the output gear to complete one full rotation.Continuing in this fashion and keeping a consistent input speed, we see that the rate of the output gear is …
