Circulating Load Calculation Formula

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

(PDF) Circulating load calculation in grinding circuits

29-09-2020· An industrial ball mill operating in closedcircuit with hydrocyclones was studied by five sampling surveys. The aim of the present study was to optimise operating parameters (i.e. charge volume

Ball Mill Circulating Load - Mineral Processing & Metallurgy

Calculating a grinding circuits 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

Circulating load - SlideShare

Ball mills are predominantly used machines for grinding in the cement industry. Empty heights of both the chambers measured to calculate the ball charge, % filling and estimate the power Circulating load to be maintained around 1.00 by optimisation of the separator parameters i.e. reduction in

(PDF) The Effect of Circulating Load and Test Sieve Size

Bond work index is being widely used to the estimate power required to grind materials. Because grindability is so widely used in mill design the assumption is often made that the method is valid without a sufficiently critical examination of the

Grinding control strategy on the conventional milling

Circulating load control The only manipulated variable available in the closed milling circuit (ball mill 2) is the cyclone dilution water flow rate. Attempts to use this for density control were not successful. Because of the high magnetite concentration of the ore it was found that the actual density exceeded the required density,


By using the obtained constant k, it is possible to calculate how long it takes for grinding, i.e. required mill revolutions to grind material when a steady state is achieved (circulating load 250%). In cases where equilibrium state is achieved with 250% circulating load: 0= 2,5 3,5 + 3,5 and =2,5 3,5 (4)
