Cone crusher basics in 4 minutes

It is vital that you know, as accurately as you can, the size distribution of the raw material. The CH cone crusher can be calibrated to achieve specific results, maximize productivity and minimize wear, but any calculation will be undermined without a solid understanding of what is going in to the crusher.

Circulating Load Equation

Despite having these methods for underflow, like what you have said, most plants determine circulating load through material balance of some sub-fraction, the water, radioactive tracers. Back to my question with a simple case, the circulating load results through sub-fraction do not match with the results using water. It's like 310% vs 700%.
