Grinding control strategy on the conventional milling circuit With the increase in ratio set point, a decrease in Cyclone 1 ... Circulating load control The only manipulated variable available in the closed milling circuit (ball mill 2) is the cyclone dilution water flow rate.
closed circuit ball mill. ... Due to this phenomenon, the magnetite grinding mills in closed circuits with hydrocyclones are less efficient and have lower capacity compared to other base metal ore grinding circuits. Figure Cyclone efficiency for magnetite Fe 3 O 4 and silica SiO 2 —industrial survey.
The reference point is a conventional ball mill circuit in closed circuit with cyclones operating at 250% circulating load and having 38% of fine material reporting to cyclone underflow, resulting in a classification efficiency of 50%. This efficiency was chosen as an industrial practice "average" from the data presented in Fig. 6.

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 ...
In my experience, from 200350% recirculating is "normal" for a closed circuit ball mill (reverse or direct). The selection of the hydrocyclones, pumps and piping sizes all go hand in hand with mill sizing selection. Perhaps the most critical thing is selecting the hydrocyclone vortex finder to ensure the cyclone overflow is clean.
Mill circuit cyclones from Multotec maximise mill efficiency and reduce the energy per ton 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 Multotec''s range of classification cyclones, facilitates increased throughput.
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 ( charge volume, makeup ball size regime, slurry mean residence time, number of hydrocyclones in operation and
Abstract. The ball mill in closed circuit with hydrocyclones is an industry standard, and well known methodologies exist for equipment sizing, selection and design; however, the potential to improve the capacity of ball mill circuits by replacing cyclones with screens has been recognised for many years and recently has been successfully realised, thanks to developments in fine screening ...
