What is Reduction Ratio?
The reduction ratio measures how much a crusher reduces the size of the input material. It is calculated by dividing the feed size by the product size.
Example: If the feed size is 100 mm and the product size is 20 mm, the reduction ratio is 5:1.
A higher reduction ratio usually means a more efficient crushing process. In industries like mining and aggregates, a good reduction ratio improves material handling, transport, and mineral liberation.
Note that reduction ratio can vary during the crushing process depending on material properties and crusher design. Sometimes multiple stages of crushing are needed to achieve the target reduction ratio.
