Reducing the power consumption of stone-ground flour mills

发布时间：2026-04-27 点击次数：

Stone-ground flour mills are currently a popular type of flour processing equipment; however, to achieve high returns, it is essential to find ways to reduce costs, with energy consumption being a key factor. Are there specific methods to reduce this?

　　1. Optimise the stone-ground flour mill process by balancing the flow and quality of materials across all systems.

　　2. Blend raw grain appropriately. In line with market demand, a sensible ratio of hard wheat to soft wheat can be adopted, which not only reduces electricity consumption per tonne of flour but also ensures flour quality.

3. Control the water addition and wheat moistening time during production to ensure the wheat reaches the optimal moisture content for milling. Achieving the optimal moisture content for clean wheat is of great significance for improving flour quality, facilitating the operation of the wheat milling machine, preventing blockages and dry grinding in the millstones, increasing output, and saving electricity.

　　4. The process flow in the stone-ground flour mill workshop employs an automated control system. The adoption of automated control systems by flour processing enterprises can shorten equipment start-up times and reduce the failure rate during the start-up process.

5. Adjust design parameters to reduce the power consumption of pneumatic conveying systems. The use of variable frequency drives for high-pressure fans not only meets process requirements but also maximises energy savings.

　　6. During workshop design and installation, direct feeding methods should be adopted wherever possible to minimise the use of horizontal conveying equipment.

7. Select suitable motors in accordance with process requirements and allocate power appropriately.

8. Minimise idle running time. Once the stone mill flour machine has started, feed material promptly and prevent interruptions in the processing flow or insufficient material levels.
