Characteristics of open- and closed-circuit grinding

Apr 15, 2004· The characteristic differences between open- and closed-circuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier. For the same median diameter of the product, the rate of powder production in the closed-circuit is about 5% higher than that of the open-circuit.

What are the advantages of open circuit system and closed

But closed circuit system is adverse to open circuit system. The advantage of closed circuit system is eliminating over grinding phenomenon and reducing temperature of grinding chamber. Then the grinding efficiency and capacity is improved. In general, the capacity can be improved by 10%-20% compared with cement mill when these specifications

Evaluation of grinding circuits for iron ore

The grinding efficiency is reduced when the circulating load increases. Research done by Wei and Craig (2009) concluded that 37% of the analyzed circuits have a single grinding stage in a closed circuit and 30% have two stages with the first mill being operated in an open circuit combined with a second mill in a closed circuit.
