The effect of circulating load on grinding capacity has long been understood. In a report published in 1925 [4], Edward W. Davis, first demonstrated the fundamental relationship between the new feed rate and the circulating load in a closed grinding circuit. His original graph of the relationship (Figure 1) has been reproduced with various modifiions in many publiions. According to this ...
4: HIGH CIRCULATING LOAD 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 circulating load. If the grinding process becomes less efficient, the circuit

without regard to circulating load. At the constant size of the cycle feed and discharge, SEC is a prime characteristic of material grindability in a certain ore pretreatment machine. For one kind material, SEC depends on the type of an ore pretreatment machine, which is connected with essential fluctuations of power transmission in active zone of various machines. The product of SEC and the ...
