Any fluctuation in pressure means that the optimal force will not be delivered consistently so, of course, crusher performance declines. These are the two main causes of suboptimal crushing performance, but losses in the reduction ratio can also be caused by selecting the wrong mantle or by having a poor chamber profile or design. Surprisingly ...

For example, with a medium limestone feed not exceeding 6" and a product requirement of 1/4", the reduction is ÷ = 24:1. With harder rocks, the max reduction ratio may be lower. When crushing to improve product shape, the reduction ratio is of lesser importance and this may be done with open circuit operation.
16/12/2015 · Jaw crusher: feed diameter to ; reduction ratio 5:1 to 10:1; capacity 1 to 300kg/s; Mohs hardness < 9 [reduction by compression]. Gyratory crusher: feed diameter to ; reduction ratio 5:1 to 10:1, usually 8:1; capacity 140 to 1000 kg/s; Mohs hardness <9. More suitable for slabby feeds than jaw crusher.
