The ball mill is in closed circuit with a sump and three cyclone classifiers. The ore and trim water are added to the ball mill and the outflow from the ball mill goes to a sump where additional water is added. The slurry from the ball mill is pumped out of a sump into two cyclone separators. The underflow from the cyclone is returned to the ball mill. Balls are added periodically to the mill on a per shift basis or when
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 8hour shift allowing to calculate corresponding to circulating load.
Apr 01 2008 Hence this condition generates an increase in the solid circulating load to the mill feed because a larger portion of the solids goes to the underflow. Then the discharge from the mill slowly becomes coarser and consequently the hydrocyclone overflow particle size becomes coarser until the operation stabilizes at a particle size slightly .
This efficiency was chosen as an industrial practice average from the data presented in Fig. 6.The relative capacity of a closed ball mill circuit as function of circulating load was calculated for three different classification arrangements1. cyclones with 38 of fine material reporting by-pass to coarse product cyclone underflow 2 .
The output is pumped into the cyclones which is made up of two 0.84-m cyclone batteries operating in reverse closed loop with two ball mills with around 300 circulating load. with approximately 70 solids. The mills feature an F80 of approximately 2500 m and operate with up to The cyclone batteries comprise 8 cyclones each. The cyclone .
Ball mill size and power selection As discussed previously ball mill circuit capacity could be increased by around 20 if cyclones are replaced with screens operating at high classification efficiency of 90 and low circulating load of 100. This means that a ball mill selected in Step 1 of the designselection process would have 20 higher .
Oct 09 2015 The circulating loads generated in a typical ball mill cyclone circuit contain a small fraction of bypassed fines. The concept that high circulating loads will result in overgrinding can be refuted by regarding increases in circulating load in the same vein as multistage grinding. That is for every incremental increase in circulating load of .
Mill circuit cyclones from Multotec maximise mill efficiency and reduce the energy per ton required.This is achieved via their unique inlet design and additionally the cyclone configuration can be altered to accommodate changing operational conditions.. Improved mill capacity by this cyclone part of Multotecs range of classification cyclones facilitates increased throughput.
Apr 01 2013 The relative capacity of a closed ball mill circuit as function of circulating load was calculated for three different classification arrangements 1. cyclones with 38 of fine material reporting by-pass to coarse product cyclone underflow 2. screens with 20 of fine material reporting to coarse product screen oversize 3.
Nov 01 2004 When feeding the mill with harder material right side of Table 1 the mill discharge becomes coarser. Consequently solids recovery circulating load and solids content will increase. With increasing solids content in the hydrocyclone feed the cut size is decreased by overflow throttling from 23 to 10 m.
Ball Mill Circulating Load. 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.
