DLT-QG Series Cement Industry Ball Mill Dedicated Drive Variable Frequency Drive
The dedicated frequency converter for cement ball mills is a high-performance speed control device developed by our company for the load characteristics of ball mills in the cement industry. It achieves precise adjustment of motor speed through vector control or VF control technology, and has functions such as high torque output, energy saving and consumption reduction, intelligent protection, etc., significantly improving the operating efficiency of ball mills and reducing maintenance costs.
FEATURES
High Torque Output
When starting the cement ball mill, it is necessary to overcome large inertia loads. A dedicated frequency converter can provide 150% -200% of the rated torque at low frequencies (such as 5Hz) to meet the requirements of heavy-duty starting.
Vector Control and VF control
Adopting vector control (SVC) or VF control mode, the former achieves decoupling of magnetic flux and torque through coordinate transformation, with fast dynamic response; The latter has a simple structure and is suitable for scenarios that do not require high speed regulation accuracy.
Multi Speed Operation
Support 3-32 speed settings, users can flexibly adjust the ball mill speed according to process requirements to optimize grinding efficiency.
Intelligent Protection Function
Integrate overload, overcurrent, overvoltage, undervoltage, overheating and other protections to extend equipment life and reduce failure rates.
Application advantages
Energy Saving
By using frequency conversion speed regulation to avoid the phenomenon of "big horse pulling small car" during power frequency operation, the energy saving rate can reach 15% -25%. For example, after a cement plant changed the power frequency operation of the ball mill to variable frequency control, the electricity consumption per unit product decreased by 18%.
Improve grinding efficiency
Accurately control the speed of the ball mill to avoid excessive grinding, shorten the grinding cycle, and improve product quality.
Extend equipment lifespan
Smooth start stop and stable operation reduce mechanical wear and maintenance costs.
Precautions
Parameter debugging: It is necessary to perform self-tuning according to the motor parameters to ensure the accuracy of vector control.
Heat dissipation design: The ball mill frequency converter needs to strengthen heat dissipation (such as air duct optimization and forced air cooling) to avoid high temperature alarms.
Harmonic control: High power frequency converters need to be equipped with reactors or filters to reduce harmonic pollution to the power grid.
