Product Specification

ACI DLT Series Ball Mill Frequency Conversion Specialized Energy-Saving Cabinet

The ball mill frequency conversion specialized energy-saving cabinet is an energy-efficient control device designed for ball mill equipment. It optimizes the operational efficiency of the ball mill and significantly reduces energy consumption through frequency conversion technology. 

I. Technical Principles

1. Frequency Conversion Speed Regulation
   Adjusts the motor speed in real time based on the different operating conditions of the ball mill. For example, high speeds are required during the coarse grinding stage to enhance impact force, while lower speeds are used in the fine grinding stage to enhance grinding precision.
2. Intelligent Control
   Automatically regulates the motor output torque and speed through sensor feedback on the material's particle size, ensuring the ball mill operates at its optimal state.
3. Soft Start Function
   Reduces the starting current by 4-7 times, avoiding grid shocks and extending equipment lifespan.

II. Core Advantages

1. High Energy Efficiency
   • Overall energy-saving effect ranges from 10% to 35%, with an average energy-saving rate of approximately 15%.
   • Reduces ineffective energy consumption by optimizing motor operating parameters.
2. Prolongs Equipment Lifespan
   • Reduces wear and tear on belts, gears, and other components, lowering failure rates.
   • Prevents damage to motors and power grids caused by startup surge currents.
3. Enhances Production Efficiency
