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,
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 ...
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. They will g
Why do ball mills have such high circulating loads?The ball mill grinds. The cyclones separate. But the pump neither grinds nor separates. So what is the purpose of having such a big pump to maintain high circulating loads in our grinding circuit?A recent
Nov 18, 2014 The Bond's work index values increased as test sieve size decreased. 16. Bond work index is changed with the change in the test sieve size and circulating load. This must be taken into account when energy consumption is calculated according to the Bond formula. unit energy cost extra increased as circulating load decreased from 250%.
Sep 29, 2020 An industrial ball mill operating in closed–circuit with hydrocyclones was studied by five sampling surveys. The aim of the present study was to optimise operating parameters (i.e. charge volume ...
bond equation for recirculating load on a ball mill Circulating Load Calculation Formula 21-02-2015 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.
The ball mill is the most common ore grinding technology today, and probably more than 50% of the total world energy consumption for ore grinding is consumed in ball mills.
Oct 19, 2017 The grinding balls diameter determined by the Bond formula has a recommendatory character and serves as a starting point for calculating the necessary proportion grinding media feeding a new mill. More precisely adjust the ball load in the mill can only by industrial test performing. During the industrial tests necessary to accurately monitor ...

micrometers in size. According to the Bond standard procedure, the work index is determined by simulating a dry grinding in a closed circuit in the Bond ball mill to achieve 250% circulating load (Bond, 1949, 1952, 1961). The test is performed on a raw material approximately weighing 10 kg, which coarseness is 100% -3.327 mm.

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
