## Closed circuit ball mill – Basics revisited ScienceDirect

1 Introduction 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 (ie its capacity to produce the desired final product)

## Closed Circuit Grinding VS Open Circuit Grinding

Open Circuit GrindingClosed Circuit GrindingGrinding Circuit Process Control VariablesGrinding Operating CostsClosed circuit grinding consists of one or more mills discharging ground product to classifiers which in turn return the coarse product from the size separation back to the mill for further grinding In this circuit, grinding efficiency is very dependent upon the size separation effected so care should be exercised in selecting the type and size of classifier used to close the system This type of grinding is the most common circuit found in mineral processing facilities, mainly because a lot of ores and product require## Ball Mill Prominer (Shanghai) Mining Technology Co,Ltd

Working Principle of Ball mill: As the mill rotates, steel balls work to grind the materials The mill rotates approximately once every couple of seconds The grinding system uses either 'open circuit' or 'closed circuit' In an open circuit system, the feed rate of materials is adjusted to
