SD300Q Ball Milling Application VFD

SD300Q – Ball Milling Application VFD is specially developed for ball mill systems, offering robust performance and reliable motor control. It provides smooth start-up, precise speed regulation, and effective torque control, ensuring stable and efficient operation of the ball mill. With built-in protection features and energy-saving capabilities, the SD300Q is an ideal solution for heavy-duty milling applications in mining, cement, and other related industries.

1. High Starting Torque Capability

Delivers strong torque at low frequencies (e.g., 150% torque at 0.5Hz), ensuring smooth start under heavy load without slipping.

2. Soft Start & Stop to Reduce Mechanical Stress

Gradual acceleration and deceleration prevent sudden shocks, protecting gears, bearings, and extending equipment life.

3. Heavy-Duty Operation Support

Designed to operate continuously under high load (150% rated current), ideal for mining, cement, and other industrial environments.

4. Stable Low-Speed Operation with Anti-Vibration Control

Advanced vector control minimizes motor jitter and ensures smooth, stable rotation during low-speed operation.

5. Multi-Speed and Timer Function

Enables multiple preset speeds and timed operation to match different process stages such as feeding, grinding, and discharge.

6. Comprehensive Protection Functions

Equipped with overload, overcurrent, overvoltage, undervoltage, phase loss, and stall protection for reliable operation.

7. Industrial Communication Support

Compatible with Modbus, CANopen, Profibus, and other protocols for centralized control and remote monitoring.

8. Rugged Design for Harsh Environments

Built to resist dust, moisture, and high temperatures, making it suitable for cement plants, mining sites, and ceramic mills.
