In order to calculate the capacity of crushers, Taggart [8] considered the size reduction, R80, as the reduction ratio of the 80% passing size of the feed, F80, and product, P80. This may be written as (4.21)
Mechanical pressure is applied using the crusher's two jaws; one is fixed while the other reciprocates. There are primary and secondary types of HSI crushers. Horizontal shaft impact (HSI) crushers are known for high reduction ratios, especially when processing soft and medium-hard materials.
What is a reduction ratio? A reduction ratio is the size a crusher will break down feed material into. In other words, the reduction ratio of a crusher tells you how big a piece of material you can feed into the crusher for it to break it up into the desired sizes.
The reduction ratio is a critical parameter for the performance of a jaw crusher. It affects the capacity, quality, and energy consumption of the machine. A high reduction ratio means a smaller product size and more fines. It also implies higher crushing force and energy consumption.

Quad Roll Crushers are capable of achieving a 4:1 reduction ratio before feeding the crushed material to the secondary stage for an additional 4:1 reduction to make the final product. Since patenting the first Single Roll Crusher in 1894, McLanahan has become an expert and leader in the design and manufacture of Roll Crushers.
Reduction of the broken rock material, or oversized gravel material, to an aggregate-sized product is achieved by various types of mechanical crusher. These operations may involve primary, secondary and even sometimes tertiary phases of crushing.
A general rule of thumb for applying Cone Crushers is the reduction ratio. A crusher with coarse style liners would typically have a 6:1 reduction ratio. Thus, with a 3⁄4" closed side setting, the maximum feed would be 6 x 3⁄4 …
