The cost of energy consumption is one of the most important subjects causing headache for the flour factories that already operate with a low-profit margin. At this point, keeping the energy costs at the minimum level and rational use of resources in the factory without making any sacrifice on the quality of the final product play a critical role in company’s profitability.

Energy Use of Fine Grinding in Mineral Processing ...

Dec 18, 2013  Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill’s energy budget.

Energy management in flour plants Miller Magazine

The amount of energy consumed during the grinding process depends on the type of mill applied, the mill settings and on the physical and chemical properties of grain and the degree of grinding. The energy consumption of the grinding process increases with grain moisture content. Energy consumption of grain grinding also depends on kernel hardness.
