Ball Mill Circulating Load Mineral Processing & Metallurgy

09/10/2015 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

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. 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

Closed circuit ball mill Basics revisited ScienceDirect

01/04/2013 Based on experience acquired over the years and the investigative work conducted by F.C. Bond, it was established that the optimum circulating load for a closed ball mill cyclone circuit is around 250%. This value is used as guideline for the design of new circuits as well as to assess the performance of existing circuits.

(PDF) Effect of circulating load and classification

Ball mill capacity tends to increase with larger circulating loads, but this increase is restricted due to limitations in classification efficiency. Classification efficiency is defined as the percent of final product size material recovered to the classifier fine stream. In literature, there are several studies investigating the effect of classification efficiency and circulating load on

Grinding control strategy on the conventional milling

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
