Based on experience acquired over the years and the investigative work conducted by Bond, it was established that the optimum circulating load for a closed ball mill cyclone circuit is around 250%. This value is used as guideline for the design of new circuits as well as to assess the performance of existing circuits.

A big advantage of tubular ID mics is that a single kit can cover a wide range of diameters. This set, for example, can measure from inches to 12 inches, or 40 mm to 300 mm, but other sets are available that measure up to 60 inches, or 1500 mm. Tubular ID mics are accurate to about one thou, or 25 microns.
