##tihuan2##If the cyclone keeps returning ore to the ball mill, the total volume of ore will be increasing in the grinding circuit. As is the density of the slurry. The recirculating ore is also called the circulating load. If the grinding process becomes less efficient, the circuit load will climb until its volume is greater than can be handled.
