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.
Jun 08 2021 Stirred Media Detritor SMD is a fluidized vertical stirred mill designed for optimum grinding efficiency for fine and ultrafine grinding products. SMDs have the capacity to operate continuously at full load power draw with no steel contamination of the product. They are suitable for both open- and closed-circuit operation.
