Primary Energy Consumption Points
Energy consumption in mill facilities is distributed across various departments and equipment:
Motor and Drive Systems: Electric motors account for approximately 60-70% of total electricity consumption in mill facilities. Roller motors, elevators, fans, compressors, and conveying systems are the main consumption points.
Grinding and Roller Systems: The highest energy consumption in facilities occurs during the grinding process. Roller machines require high motor power due to high-torque operations.
Pneumatic Conveying Systems: Pneumatic systems used for transporting products and intermediate products are significant energy consumers due to their high-pressure air requirements.
Lighting and Climate Control: Facility lighting and ventilation systems, especially those used in dusty environments, create significant consumption as they operate continuously.
Cleaning and Preparation Section: Grain cleaning equipment, stone separators, and hullers are high-power systems that operate continuously.
Common energy loss points in mill facilities:
Obsolete and Low-Efficiency Motors: Old motors in IE1 or lower efficiency classes consume 10-15% more energy compared to modern high-efficiency alternatives.
Non-Optimized Load Profiles: Motors not operating at full load or oversized motors operate below their nominal efficiency.
Air Leakages and Pressure Losses: Leakages in pneumatic systems can cause losses of up to 20-30% of total air consumption.
Insulation Deficiencies: Inadequate insulation leads to significant energy losses, especially in thermal processes like tempering and drying.
