Energy-Saving Retroft For Copper Flotation Machines

This retrofit supports green and sustainable development goals by lowering energy use and carbon emissions, while also reducing maintenance needs and operating costs.

 

Project Background:

In a copper ore processing plant, multiple flotation machines (models XCF II/KYF II-10 and XCF II/KYF II-50) were originally equipped with asynchronous motors and belt pulley transmission systems. These systems had relatively low mechanical and energy efficiency.

 

Solution

 

  • To improve efficiency and reduce energy consumption, we upgraded the flotation machines by replacing asynchronous motors with high-efficiency permanent magnet direct drive motors. This eliminated the need for the traditional belt pulley system, reducing mechanical losses.

 

 

After Retrofit

 

  • Power consumption reduced from 75kW to 55kW
  • Operational efficiency improved from 85% to 92%
  • Transmission efficiency increased from 90% to 99%
  • Operational power dropped from 43.7kW to 35.5kW
  • Comprehensive energy saving rate exceeded 18%
