Large-scale potash fertilizer beneficiation complex project with a capacity of 2 million tons

 

 

 

Project Name: Large-Scale 1.1-2.2 Million Ton Potash Fertilizer Beneficiation Complex Project

Project Location: Eastern Europe

Project Positioning: A benchmark large-scale energy and mineral project for Sino-foreign economic and trade cooperation. With a total investment of approximately RMB 10 billion, the project integrates modern mining, potash fertilizer beneficiation and processing, a self-owned gas-fired power plant, and comprehensive supporting infrastructure. It is planned to produce 2 million tons of potassium chloride annually. Upon completion, it will significantly enhance the region's potash fertilizer production capacity and market supply capacity, making it a core pillar mineral and energy project in the area. The project adopts a combined power supply architecture of a self-owned power plant and a beneficiation plant, implementing a 24-hour uninterrupted continuous production mode. It has extremely high requirements for grid stability, power supply reliability, and power quality.

Industry Power Consumption Pain Points: Potash fertilizer beneficiation production involves complex processes, including crushing, grinding, conveying, flotation, dewatering, and tailings treatment. These processes utilize numerous high-power crushers, variable frequency conveyors, flotation machines, and centrifugal dewatering machines, subject to impact and nonlinear loads. Frequent start-ups and shutdowns of these equipment clusters, coupled with severe instantaneous load fluctuations, easily lead to power quality issues such as excessive system harmonics, voltage flicker, low power factor, and three-phase load imbalance. Furthermore, the stability of the mine's self-provided power station is weaker than the public power grid. The start-ups and shutdowns of high-power equipment can cause grid disturbances and bus voltage fluctuations, easily resulting in malfunctions in automated control systems, data drift in precision instruments, and production line shutdowns. This severely impacts beneficiation capacity and continuous production efficiency, posing multiple hidden dangers including high equipment wear and tear, high maintenance costs, and poor production stability.

 

 

Leonhard Electricity is the dedicated supplier for comprehensive power quality management in this project. It is deeply adapted to the combined power supply scenario of a large-scale potash fertilizer mine's self-owned power station and ore dressing plant. It adopts an integrated solution of "front-end SVG main voltage stabilization filter + end-end NTPS full-domain fine protection," specifically addressing industry pain points such as high-power impact loads in the mining industry, large fluctuations in the self-owned power grid, severe harmonic pollution, and insufficient reliability of continuous production power supply. This comprehensively ensures the long-term stable operation of the entire ore dressing complex.

 

1. SVG Dynamic Power Management for the Main Circuit of the Plant

For the project's self-owned power station and the main power distribution system of the ore processing plant, SVG core equipment from Leonhard Static Var Generators was deployed in batches. This equipment is precisely adapted to the high-power impact load conditions of all processes, including potash fertilizer beneficiation, ore crushing, material conveying, and dewatering. The equipment possesses millisecond-level ultra-fast dynamic response capabilities, enabling real-time tracking of instantaneous load fluctuations caused by the start-up and shutdown of mining equipment clusters. It quickly and dynamically compensates for system reactive power, effectively improving the overall plant power factor and eliminating reactive power losses and grid performance penalties. Simultaneously, it precisely suppresses various harmonics generated during equipment operation, stabilizes bus voltage, and eliminates voltage dips and flicker problems. This completely solves the core problems of large grid fluctuations and poor power quality in the self-owned power station, ensuring load balance and stable operation of the entire large-scale ore processing production line.

 

2. Comprehensive NTPS Electrical Management and Protection System for the Entire Plant

An NTPS terminal electrical management and protection system is comprehensively deployed across all production terminal circuits, central control automation systems, precision testing instruments, electrical control cabinets, and auxiliary power distribution circuits in the ore dressing workshop. This system meticulously manages residual harmonics, high-frequency electromagnetic interference, three-phase load imbalance, and abnormal neutral current, effectively eliminating grid noise disturbances under complex mining conditions and preventing faults such as signal disturbances in the automatic control system, equipment malfunctions, and production parameter drift caused by grid interference. It also provides overload, leakage, and abnormal fluctuation protection capabilities, comprehensively protecting the plant's precision electrical equipment and automated control systems, significantly reducing equipment failure rates and line aging losses, perfectly meeting the stringent requirements of 24-hour continuous production in potash fertilizer projects.

 

3. Mine-Specific High-Reliability Power Supply and Energy Efficiency Optimization Solution

Deeply adapted to the combined power supply architecture of the project's self-contained gas-fired power plant and ore dressing plant area, and combined with the power grid standards and production characteristics of large-scale potash fertilizer mines, this solution customizes and optimizes the overall power distribution operation. It effectively suppresses grid disturbances caused by frequent start-ups and shutdowns of high-power mining equipment, balances the three-phase load of the system, reduces line heat loss and equipment energy consumption, comprehensively improves the power supply security, operational stability, and overall energy efficiency of the ore dressing complex, addresses the shortcomings in energy infrastructure of large-scale mines, and ensures long-term, efficient, low-cost, and continuous mass production operation of the project.
