V/F Control Adjustable Frequency Drive 20hp VFD for Ball Mill 220V-380V

Product Specification

DLT-QG Series V/F Ball Mill Dedicated Drive Variable Frequency Drive

The V/F control ball mill dedicated frequency converter is designed by our company specifically for the load characteristics of the ball mill. We use constant voltage frequency ratio (V/F) control technology to achieve smooth adjustment of motor speed by adjusting the ratio of output voltage to frequency. This frequency converter is known for its high cost-effectiveness, stability, and reliability. It is widely used in energy-saving renovations of ball mills in industries such as mining, cement, and ceramics, helping enterprises reduce energy consumption and improve production efficiency.

FEATURES

• Energy conservation and consumption reduction, cost reduction and efficiency improvement
  V/F control technology: Below the rated frequency, the output voltage is proportional to the frequency to ensure constant motor flux, avoid insufficient low-frequency excitation or high-frequency magnetic saturation, and improve motor efficiency.
  Significant energy-saving effect: By optimizing the speed and load matching, reducing useless power loss, the comprehensive energy-saving rate can reach 15% -30%, significantly reducing the enterprise's electricity expenses.
• Overload start, smooth operation
  High starting torque: Supports 150% rated torque output at 0.5Hz, easily meets the heavy load starting requirements of ball mills, and avoids the impact of excessive starting current on the power grid and equipment.
  Soft start function: achieve smooth acceleration, reduce mechanical wear, and extend equipment service life.
• Precise speed regulation, process adaptation
  Wide speed range: The speed ratio can reach 1:100, with a speed accuracy of ± 0.5%, meeting the speed requirements of different process stages of the ball mill to ensure the grinding effect.
  Multi speed operation: supports up to 32 speed settings, flexibly matches grinding, conveying and other process flows, and improves production automation level.
• Intelligent protection, safe and reliable
  Multiple protection mechanisms: integrated overcurrent, overvoltage, undervoltage, overload, overheating and other protection functions, real-time monitoring of equipment operation status, automatic shutdown in case of abnormalities, ensuring production safety.
  Strong environmental adaptability: IP55 protection level, resistant to dust and corrosion, suitable for some harsh working conditions.

Application
