IP55 Waterproof 3 Phase Variable Frequency Drive Inverter SVC Control

DLT-QG Series Ceramic Industry Ball Mill Dedicated Drive Variable Frequency Drive

The ceramic industry ball mill dedicated frequency converter is a specialized equipment developed by our company based on the characteristics of the ceramic industry ball mill process. Through frequency conversion speed regulation technology, it achieves energy-saving operation, precise control, and efficient production of ball mills.

FEATURES

• Specialized Control Algorithm
  Optimize the PID control algorithm for the low-speed heavy load and large inertia load characteristics of the ball mill to ensure low-frequency high torque output (such as up to 180% rated torque at 1Hz) and meet the requirements for heavy load starting.
  Support Vector Control (SVC) and V/F control modes to adapt to different operating conditions.
• Energy Saving
  By adjusting the motor speed to match the optimal grinding efficiency and avoiding excessive grinding, the comprehensive energy-saving rate can reach 10% -35%.
  Built in automatic energy-saving function, dynamically adjusting output voltage and frequency according to load, reducing reactive power loss.
• Intelligent Functions
  Multi speed operation: up to 32 preset speeds can be set to meet the needs of different grinding stages.
  Automatic Voltage Regulation (AVR): When the grid voltage fluctuates, it maintains stable output voltage to ensure the normal operation of the equipment.
  Built in PLC function: supports logic control, timing control, and achieves automated production.
• Protection Function
  It has comprehensive protection against overcurrent, overvoltage, undervoltage, overload, overheating, and phase loss, extending the service life of the equipment.
  Fault self diagnosis function, quickly locate the cause of the fault, and reduce downtime.
• Environmental Adaptability
  Wide voltage design (such as 380V ± 15%), suitable for the complex power grid environment of ceramic factories.
  High protection level (such as IP55), dustproof and waterproof, suitable for high temperature and dusty ceramic production environment.

Application advantages

• Improve Grinding Efficiency
  By using variable frequency speed regulation, the ball mill can always operate within the optimal speed range, improving grinding efficiency and product quality.
• Reduce Maintenance Costs
  The soft start function reduces mechanical impact, extends the lifespan of components such as motors, reducers, and gears, and reduces maintenance frequency.
• Optimize Production Management
  Implement automated control, reduce manual intervention, and improve production consistency and stability.
  Real time monitoring of equipment operation status facilitates data analysis and production scheduling.
• Environmental Benefits
  Energy conservation and consumption reduction, reduction of carbon emissions, in line with green production requirements.

Application Cases

• A ceramic factory in Guangdong
  After adopting a specialized frequency converter for a certain brand of ball mill, the annual power saving of a single ball mill is about 200000 kWh, the motor starting current is reduced from 600A to 150A, and the equipment failure rate is reduced by 60%.
• A building materials enterprise in Fujian
  By using variable frequency speed regulation to match the ball mill speed with the material particle size, the product qualification rate has been increased to 98%, and the annual maintenance cost has been reduced by 300000 yuan.
