2013-4-1 Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e.
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
The ball mill in closed circuit with hydrocyclones is an industry standard, and well known methodologies exist for equipment sizing, selection and design.
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%.

Static and dynamic or high efficiency air separators are being used widely in closed circuit with multi-compartment tube ball mills, High Pressure Grinding Rolls (HPGR) and more recently Vertical
Spreadsheet-based simulation of closed ball milling circuits. A. Farzanegan. IntroductionGrinding process mathematical modelling and computer simulation particularly in mineral industry had been a very active research field for several past decades. This is due to the high consumption of electrical energy in comminution circuits and low efficiency
2006-12-1 Plitt and Nageswararao models have been used to describe the performance of hydrocyclones, which by linking to the ball mill model allow for closed-circuit simulations. To describe material flow through the ball mills, two tanks-in-series models called Weller’s model and one plug flow unit plus n perfect mixers units (1PF + n PM) model have been used.
