Cement mill - Wikipedia

The proportion of the mill-exit material returned to the inlet may vary from 10-30 when ordinary cement is being ground, to 85-95 for extremely fine cement products. It is important for system efficiency that the minimum amount of material of finished-product fineness is returned to the inlet. Modern separators are capable.
