Intelligent Three Phase Variable Frequency Controller Inverter Drive 220v

DLT-QG Series Intelligent Control Ball Mill Dedicated Drive Variable Frequency Drive

The Intelligent Control Ball Mill Dedicated Drive Variable Frequency Drive is a variable frequency speed regulation device designed specifically for ball mills, combining intelligent control technology with variable frequency drive functions to optimize the operating efficiency of ball mills, reduce energy consumption, and improve equipment reliability.

Core Functions

• Intelligent Control
  Built in PLC or microprocessor, supports multi-stage automatic operation, can preset grinding time, grinding time, and automatic shutdown function.
  Equipped with adaptive control capability, it can automatically adjust the motor speed according to load changes to achieve the best grinding effect.
  Support remote monitoring and fault diagnosis, integrate with the upper computer or DCS system through communication interfaces (such as Modbus, Profibus) to achieve real-time data acquisition and status monitoring.
• Variable Frequency Drive
  Adopting vector control or direct torque control (DTC) technology, providing high-precision torque and speed control, fast dynamic response, and wide speed range.
  Support soft start function, eliminate startup shock, extend device lifespan, and reduce maintenance costs.
  The energy-saving effect is significant, and by optimizing the motor speed and load matching, the comprehensive energy-saving rate can reach 12% -30%.

Technical advantages

• High Reliability
  Equipped with multiple safety mechanisms such as overload protection, overvoltage protection, and undervoltage protection to ensure stable operation of the equipment.
  Adopting industrial grade hardware design to adapt to harsh working conditions such as high temperature, dust, and vibration.
• Ease of Use
  Humanized operation interface, supporting one click parameter setting and debugging.
  Remote parameter adjustment and status monitoring can be achieved through a mobile app or web interface.
• Extensibility
  Supporting energy feedback function, the braking energy is fed back to the power grid to further enhance energy-saving effect.
  Optional power frequency switching function, automatically switches to power frequency mode in case of frequency converter failure, ensuring continuous production.

Selection Suggestions

• Select based on power requirements:
  Small ball mill (≤ 55kW): Low voltage frequency converter (such as 380V) is recommended.
  Large ball mill (>55kW): It is recommended to use a high-voltage frequency converter (such as 3kV or above).
• Select based on control accuracy:
  Scenarios with high requirements for speed regulation accuracy: prioritize vector control or DTC type frequency converters.
  Cost sensitive scenarios: V/F control type frequency converters can be considered.
