Tips for maintaining efficiency in crushing circuits

01-04-2019 0183 32 Crushing setting Efficiency Ideally, the reduction ratio of a jaw crusher should be 6 1 There are different ways to calculate reduction ratio, but the best way is something called the P80 factor The reduction ratio is then calculated by comparing the input feed size passing 80 per cent versus the discharge size that passes 80 per cent...

CHAPTER 11 SIZE REDUCTION

Kick assumed that the energy required to reduce a material in size was directly proportional to the size reduction ratio dL/L This implies that n in eqn 111 is equal to -1 If K = K K f c where K K is called Kick s constant and f c is called the crushing strength of the material, we have dE/dL = -K K f c L 1 which, on integration gives E ....
