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

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

The concept and theory to best understand a Ball Mill Circulating Load is shown here as an excerpt from Arthur and Ball mill circulating load PPT Circulating load

Effect of circulating load and classification efficiency on HPGR and ball mill capacity

The effect of circulating load and classification efficiency on the performance of ball mill circuits is compared to the effect on HPGR circuits. The fundamentals of grinding behavior are also

Why do ball mills have such high circulating loadsThe 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 circuitA recent grinding bulletin addresses this question f

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

Slide 3 circulating load ratio : As the ratio of the amount of solids going through the ball mill divided by the amount of solids going through the circuit. Circulating load circulating load ratio New feed circulating load ratio 4.

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

circulating load for ball mill . VRM and ball mill circulating load Page 1 of 1. Sep 07, 2011· Re: VRM and ball mill circulating load. Mainly in USA, the term circulating load is more often used than the circulation load is percentage of coarse return in relation to fines it can be calculated by : Coarse return TPH X 100 / Mill output range of cirulating load in a conventional close circuit

07/09/2011· Re: VRM and ball mill circulating load. Mainly in USA,the term circulating load is more often used than the circulation factor.Circulating load is percentage of coarse return in relation to fines & it can be calculated by : Coarse return TPH X 100 / Mill output TPH.Normal range of cirulating load in a conventional close circuit ball mill is around 100-200%.

In pract circulating loads between ball mills and classifiers are rarely less than 200 per cent and frequently exceed 700 per cent It may appear strange at first sight that the circulating load between a mill and classifier producing for example 100 tons of finished product per day can be as much as 400 tons or more but this will be made clear by Fig 71

Ball Mill Circulating Load Calculations. Ball mill load calculations circulating load calculation formula 911 metallurgist sep 10 2017 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

01/01/2013· At each iteration the circulating load (CL) is calculated using the following equation: %% L Ãá :LÜ ä BÜ ; Ü@5 (2) The circulating load calculation shown in equation 2 differs from the one proposed by Tsakalakis (2000) by combining the unit operations efficiencies in a single parameter (pi). The exact result obtained by the author with the use of monographic can also be obtained by using

Key words: ball mill; circulating load; classification; efficiency; model. 1. Introduction Closed ball mill cyclone circuits are industry standard and it is recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding. The individual effect of circulating load and classification efficiency is difficult to quantify in

If circulating load in the second ball mill is kept constant, any variation in the fresh feed will ultimately be reflected in the product particle size of Cyclone 2. Water addition to Cyclone 1 feed sump therefore not only controls the Cyclone 1 product particle size, but ultimately also Cyclone 2 product particle size. Size ratio control A new variable, called the particle size ratio was
