Crusher Types Commonly Used on Track-Mobile Plants
The reduction ratio is the ratio of the max infeed size compared to the crusher max output size. It varies depending on the crusher type, settings, and material. The higher the reduction ratio the smaller the output product. A reduction ratio of 1:10 means that a 20" chunk entering a crusher leaves as 2" crushed product.
