DLT-QG Series Soft Start Ball Mill Dedicated Drive Variable Frequency Drive

The soft start type ball mill dedicated frequency converter is a frequency conversion drive device designed specifically for ball mills. Through soft start and speed regulation functions, it solves the problems of high impact current, high energy consumption, and low grinding efficiency caused by traditional power frequency starting.

The soft start ball mill dedicated frequency converter developed and produced by our company has been widely used in industries such as ceramics, cement, metallurgy, and mining, helping enterprises achieve energy conservation and consumption reduction, improve production efficiency and product quality.

• Soft start function: reduces the impact of starting current on equipment and power grid, and the starting current can be 3-5 times smaller than before, achieving smooth soft start.
• Dynamic power-saving function: It has a unique dynamic power-saving function, with a power-saving rate of up to 10% -35%.
• High overload capacity: The starting torque is large, and it can reach 180% of the rated torque output at low speeds; Strong overload capacity, can run for 1 minute at 150% rated current, and can directly start the ball mill without auxiliary equipment.
• Precise control: using vector control or V/F control technology, low-frequency output full torque, smooth start stop, and precise speed tracking.
• Wide voltage design: It has automatic voltage stabilization function, adapts to complex power grid environment, and ensures stable operation of the motor under harsh working conditions.

• Improve grinding efficiency: By adjusting the motor speed, the ball mill can operate at an effective working speed in different grinding stages to improve grinding efficiency.
• Reduce energy consumption: Achieve continuous adjustable operating speed of the ball mill, reduce unnecessary energy waste, and lower power consumption per unit product.
• Extend equipment lifespan: Reduce the impact and wear of motors and mechanical equipment, lower maintenance costs, and extend equipment lifespan.
• Enhance equipment stability: With comprehensive motor drive protection functions, including overload, overcurrent, overvoltage, undervoltage, short circuit, phase loss, and power outage protection measures, the equipment ensures safe and stable operation.
• Realize automation control: Support fieldbus technology, which can achieve real-time display of equipment status, control automation, and intelligent monitoring, reducing manual operations.
