How to adjust crushing ratio to increase the cubic shape of …
Ok, the above is all about how the crushing ratio affects the crushed material shapes and how we can get better product shapes by controlling the crushing ratio. In conclusion, a single crusher always has a certain range of crushing ratio, for example, a jaw crusher's crushing ratio ranges from 3 to 20 depending on its type.
Crushing in Mineral Processing
In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.

Reduction Ratio: Why It Is So Important For Crushing?
The reduction ratio in crushing is the ratio of the feed size to the product size during a crushing operation. It usually varies, but the reduction ratio depends on the chamber and nut adjustments. However, the best particle shape is found in material about the same size as the CSS, which is the smallest discharge opening dimension on the jaw ...
