Calculating Mill Recirculating Load. The Effect of Circulating Load and Test Sieve Size on The In this study, the effect of circulating load (CL) and test sieve size (P,), which are inaccuracies of Bond grindability, on the Bond ball mill grindability (Ghg) and work index
What is the most reliable method to determine actual circulating load in grinding circuit? A simple one ball mill w/ hydrocyclone. I observed that the most common methods applied are (1) use of water balance taking samples of cyclone feed, cyclone underflow and cyclone overflow.
Unfortunately most cyclones will report high percentages of fines back to the ball mill resulting in high recirculating loads. Applying a more efficient separation technology, circulating loads are not only reduced, but in many cases where multiple mills are installed, are idled.
Recirculating Load In Ball Milling Formula. ball mill recirculating load calculation pdf. primary wet autogenous mill (WAM) and a series of ball mills WAM is, is a ratio of the mill drive power to the milling circuit output, without regard to circulating load At the constant, milling, Barratt presented another formula for SEC required

Calculating a grinding circuit’s circulating loads based on Screen Analysis of its slurries. Compared to %Solids or Density based Circulating load equations, a more precise method of determining grinding circuit tonnages uses the screen size distributions of the pulps instead of the dilution ratios. Pulp samples collected around the ball mill or rod mill and hydrocyclones, screen or
Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating load

others in Allis-Chalmers have developed a grinding test in a ball mill in a closed cycle until the establishment of stable recirculating load (Maxson et al., 1933). The Bond work index is a parameter which represents a measure of an ore resistance to grinding. Numerically, the work index represents the energy (kWh/sht)
how to calculate circulating load. puritic ore, calculated Bond work index is higher with different circulating loads, the Bond work index is higher with lower circulating loads. The purpose of this Why Do We Need Such A High Recirculating Load On Our Ball Mill.
The test results confirmed the beneficial effect of circulating load, and also that the throughput benefits of higher circulating load are limited due to classification efficiency. The effect of classification efficiency and circulating load was also investigated by Morrell (2008) who used Bond ball mill tests as the base line (Bond
