06/07/2014 · Closedcircuit system broken product particle size is controlled by check screen size, and broken open system products often contains too much greater than the specified size of particles. In the process of crushing and screening homework, composed of coarse crushing, crusher, finely or ultra fine grinding process is called the broken screen ...

20/10/2016 · This problem is generally solved by wet grinding in a rod mill or in this case it may be called wet fine crushing. In closed circuit grinding the feed enters one end of the mill and is discharged from the other end into some type of classifier. This classifier is to limit maximum particle size removed from the mill circuit.

This is reasonable as no crushing circuit operates anywhere near that size range. There is a minor correction required for open circuit secondary crushing (the factor becomes ). In theory, open circuit operation would change the particle size distribution of the secondary crusher product affecting the load on the tertiary crusher.
